How to Review a Portable Earthing Set Drawing Before Production: Buyer Approval Checklist
A portable earthing set should not enter production only because the purchase order has been issued.
For custom or project-based portable earthing and short-circuiting equipment, the supplier normally needs to convert the approved RFQ, technical schedule, connection-point information, cable arrangement, clamps, and fault-duty requirement into a controlled assembly drawing.
That drawing becomes an important pre-production control document.
For utility buyers, EPC contractors, consultants, and technical procurement teams, the main review question is not:
Does the drawing look complete?
Күшті сұрақ:
Does the proposed production drawing accurately represent the approved project requirement, and is the configuration supported by the required technical evidence?
The key approval chain is:
Approved RFQ → Supplier Drawing → Technical Review → Comments → Revised Drawing → Approval → Release for Production → FAT
The purpose of drawing approval is to identify configuration errors before manufacturing begins.

Quick Answer: What Must Be Approved Before Manufacturing?
Before releasing a portable earthing set for production, buyers should confirm:
- Сурет нөмірі және қайта қарау
- Correct project and PO reference
- Approved connection topology
- Number of phase and earth leads
- Individual cable cross-sections
- Жеке кабель ұзындықтары
- Phase clamp models and interfaces
- Earth clamp model and interface
- Феррулдар және терминалдар
- Connecting cluster or common point
- Operating pole and adapters
- Fault-current duty reference
- Compatibility with supporting test evidence
- BOM consistency
- Таңбалау және бақылау
- Declared technical deviations
- Closed review comments
- Final production-release status
A strong drawing-review process follows:
Specification → Configuration → Interfaces → Evidence → Revision Control → Approval
The drawing should translate an approved procurement requirement into a manufacturable assembly.
It should not silently rewrite the requirement.
For the upstream specification stage, see Тендердегі портативті жерге қосу жинағын қалай көрсету керек.
Why the Production Drawing Is a Control Document
A portable earthing set may contain:
- Фазалық қысқыштар
- Жерге қысқыш
- Икемді өткізгіштер
- Фазалық сымдарды
- Жер қорғасыны
- Феррулалар
- Қақпақтар
- Кластерді қосу
- Ортақ қосылу нүктесі
- адаптерлер
- Оқшаулағыш жұмыс полюсі
- Сақтау керек-жарақтары
These components work as one system.
The drawing should therefore do more than show the product shape.
It should define the approved configuration.
A controlled production drawing helps connect:
Сатып алушының талабы
дейін
Supplier proposal
дейін
Өндіріс
дейін
FAT
дейін
Жеткізілген өнім
If that link is weak, problems often appear later as:
- Wrong cable lengths
- Wrong clamp models
- Incorrect topology
- Жетіспейтін аксессуарлар
- Unsupported substitutions
- BOM differences
- Fault-duty evidence that applies to another configuration
These issues are much easier to correct before production.
Step 1: Confirm Drawing Number, Revision, and Project Reference
Before reviewing the technical details, confirm that you are reviewing the correct document.
Тексеріңіз:
- Drawing title
- Сурет нөмірі
- Қайта қарау нөмірі
- Қайта қарау күні
- сатып алушы
- Жоба
- Сатып алуға тапсырыс
- Tender or contract reference
- Жеткізуші моделі
- Элемент нөмірі
- Prepared-by information
- Checked-by information
- Бекіту күйі
This seems simple, but revision control is one of the most important parts of pre-production approval.
Мысалға:
Revision A
- 50 мм² кабельдер
- 1.5 m phase leads
- 3 m earth lead
- Clamp model A
Revision B
- 70 мм² кабельдер
- 2 m phase leads
- 5 m earth lead
- Clamp model B
If the project approved Revision B but production uses Revision A, the final product can be wrong even though both drawings look technically complete.
Check the revision before checking the components.
Do not release production from an uncontrolled screenshot, quotation attachment, or old email drawing when the project requires formal document control.
Step 2: Compare the Drawing With the Approved RFQ
The next step is to compare the supplier drawing with the approved procurement requirement.
Review the major engineering inputs:
- қолдану
- Айнымалы немесе тұрақты ток жүйесі
- Жүйелік контекст
- Бекітілген ақаулық тогының міндеті
- Бағаланған уақыт
- Peak-current requirement where applicable
- Фазалар саны
- Жерлендіруді ұйымдастыру
- Қосылу нүктелері
- Кабельдің көлденең қимасы
- Кабель ұзындығы
- Қысқыш интерфейстері
- Жермен байланыс
- Операциялық полюс талабы
- керек-жарақтар
- Таңбалау
- Құжаттама
The supplier drawing should reflect the accepted technical offer.
It should not introduce new assumptions.
For example, if the RFQ states:
70 mm² flexible copper conductors
the production drawing should not show:
50 мм²
without an approved technical deviation.
Likewise, if the project requires:
flat-busbar phase clamps
the supplier should not replace them with another clamp type without declaring the change.
The supplier drawing should translate the approved specification into a manufacturable assembly, not silently modify the specification.
Step 3: Verify the Connection Topology
“Three-phase portable earthing set” does not define one universal arrangement.
The drawing should clearly show how the complete current path is arranged.
Тексеріңіз:
- Фазалық қысқыштар саны
- Фазалық сымдардың саны
- Фазааралық қосылымдар
- Жерге фазамен өту жолы
- Жалпы кластер
- Individual earth leads
- Common earth lead
- Филиалдың орналасуы
- Қажет болған жағдайда бейтарап қосылым
- Earth connection point
A buyer should be able to understand the electrical topology without guessing from the cable count.
Мысалы, жоба мыналарды талап етуі мүмкін:
Three phase branches → common cluster → one earth lead
немесе:
Үш тәуелсіз фазаға-жерге қосылатын сым
These are different assemblies.
Толық түсініктеме алу үшін қараңыз портативті жерге қосу құрылғыларындағы фазааралық және фазалық-жерге қосылымдар.
During drawing approval, the question is simpler:
Does the supplier drawing show the same topology that the engineer approved?
Step 4: Review Every Cable and Lead Separately
Do not approve the drawing from one general cable statement.
A multi-phase assembly may contain several different lead lengths.
Review each lead separately.
A useful schedule can look like this:
| қорғасын | дирижер | Көлденең қима | ұзындық | -дан | Кімге |
|---|---|---|---|---|---|
| А фазасы | мыс | 70 мм² | Жобаның құны | Phase clamp | Кластер |
| B кезеңі | мыс | 70 мм² | Жобаның құны | Phase clamp | Кластер |
| C кезеңі | мыс | 70 мм² | Жобаның құны | Phase clamp | Кластер |
| Жер қорғасыны | мыс | 70 мм² | Жобаның құны | Кластер | Жерге қысқыш |
Depending on the project, also confirm:
- Кабель құрылысы
- Sheath or insulation
- түс
- Flexible conductor requirement
- Сәйкестендіру
- Аяқталу түрі
Avoid one vague drawing note such as:
Cable length: 5 m.
That does not explain whether 5 m refers to:
- Every phase lead
- Кабельдің жалпы ұзындығы
- Жер қорғасыны
- Бір филиал
- Толық құрастыру
For technical approval, each important lead should be identifiable.
Step 5: Compare Lead Lengths With Site Geometry
Cable length should not be approved from the supplier drawing alone.
Compare the proposed lengths with the actual connection geometry.
Useful engineering inputs include:
- Фаза аралығы
- Шина аралықтары
- Жабдықтың ені
- Connection-point position
- Жер нүктесінің орналасуы
- Жабдықтың биіктігі
- Шкафтың тереңдігі
- Бекітілген кабельдік маршрут
- Кіруді шектеу
The purpose is not to create a field installation procedure.
Мақсат - жауап беру:
Does the proposed assembly physically fit the approved connection points?
For example, an earth lead that is technically suitable in cross-section may still be unsuitable if the approved earth point is farther away than the proposed cable can reach.
Likewise, excessively long leads may affect:
- өңдеу
- сақтау
- маршруттау
- Assembly geometry
- Техникалық дәлелдеме
Do not approve cable length from the principle:
Longer is safer.
The required length should come from the approved project geometry.
Step 6: Match Phase and Earth Clamps to the Actual Interfaces
Сөздер:
әмбебап қысқыш
are not enough for drawing approval.
Each clamp should be linked to a real connection point.
For phase clamps, review:
- Қысқыш моделі
- Jaw design
- Жақтың ашылу қашықтығы
- Flat or round conductor interface
- Busbar dimensions
- Өткізгіштің диаметрі
- Ball-stud interface where applicable
- Бетке жабысатын дизайн
- Кабельдік байланыс
- Операциялық полюс интерфейсі
For the earth clamp, review:
- Жер жолағы
- Rod
- Stud
- Fixed terminal
- Structural earth point
- Other approved connection geometry
The drawing or BOM should identify which clamp is used at each location.
A clamp should be approved against an interface, not only against a product name.
A photograph may help explain the site condition, but dimensions are more useful when clamp fit depends on geometry.
Step 7: Review Ferrules, Terminations, and the Connecting Cluster
Cable cross-section is only one part of the current path.
The drawing package should also identify how the flexible conductor connects to:
- Phase clamp
- Жерге қысқыш
- Кластерді қосу
- шілде
- Аяғын орнату
Шолу:
- Ferrule reference
- Lug reference where applicable
- Cable-to-clamp connection
- Cable-to-cluster connection
- Аяғын орнату
- Strain-relief arrangement where specified
- Component reference
The production drawing does not always need to show every manufacturing detail.
However, the termination should be defined well enough to prevent uncontrolled substitution.
Do not approve the conductor size while leaving the termination undefined.
For detailed termination inspection criteria, see grounding cable terminations: ferrules, lugs, and clamp connections.
Do Not Ignore the Cluster
For clustered multi-phase sets, the common connection point is part of the complete current path.
Тексеріңіз:
- Cluster model
- Филиалдар саны
- Кабельді қосу әдісі
- Earth-lead connection
- Component reference
- Arrangement in the assembly
A cluster is not simply an accessory between several cables.
Its configuration can be relevant to the complete assembly evidence.
Step 8: Compare the Production Drawing With Fault-Duty Evidence
This is one of the most important approval steps.
The drawing may look correct geometrically but still differ from the configuration supported by the supplier’s test evidence.
For portable earthing and short-circuiting equipment, buyers should review:
- Номиналды ток
- Бағаланған уақыт
- Ең жоғары ток негізінде
- Кабельдің көлденең қимасы
- Кабель ұзындығы
- Фазалық қысқыштар
- Жерге қысқыш
- Феррулалар
- Кластер
- Филиалдың орналасуы
- Complete tested configuration
The production drawing should be compared with the drawing or configuration referenced by the supporting evidence.
Мысалға:
Тексерілген конфигурация
- 70 mm² conductor
- Clamp A
- Ferrule F1
- Cluster C1
- Defined branch arrangement
Proposed Production Drawing
- 50 mm² conductor
- Қысқыш B
- Ferrule F2
- Cluster C2
- Different lead arrangement
These should not automatically be treated as the same product because both documents show:
25 кА.
A buyer should ask:
Does the available fault-duty evidence actually support the configuration shown on the production drawing?
For a detailed rating review, see portable earthing kit fault-current rating.
Compare Three Technical Configurations Before Approval
A strong review normally connects three different engineering references.
1. Project Requirement
This describes what the site needs.
Ол мыналарды қамтуы мүмкін:
- Қосылу нүктелері
- Required topology
- Ақаулық міндеті
- Қашықтық
- Қолжетімділік шарттары
2. Tested Configuration
This shows what the supplier’s technical evidence actually supports.
It may identify:
- кабель
- қысқыш
- шнурковых
- Кластер
- Лидтерді орналастыру
- Test duty
3. Proposed Production Drawing
This shows what the factory intends to manufacture.
Before approval:
Production Drawing must match the Project Requirement
және
Technical Evidence must support the Production Drawing
After manufacturing, a fourth comparison is added:
4. Finished Product
That becomes part of FAT.
This creates a clean evidence chain:
Project requirement → Tested configuration → Approved production drawing → Finished assembly
Step 9: Check the Drawing Against the BOM
Do not review the assembly drawing without the Bill of Materials.
A drawing can be technically correct while the BOM still contains the wrong component.
Мысалға:
Сурет салу
Phase clamp: C-100
BOM
Phase clamp: C-120
If manufacturing follows the BOM, the finished equipment may not match the approved drawing.
Тексеріңіз:
- Drawing item number
- BOM item number
- Компонент атауы
- Бөлшектің нөмірі
- сан
- Material where specified
- Component revision
- Жеткізуші моделі
Typical BOM items may include:
- Фазалық қысқыштар
- Жерге қысқыш
- Phase cables
- Жерге қосу кабелі
- Феррулалар
- Қақпақтар
- Кластер
- адаптерлер
- Жұмыс полюсі
- Pole head
- Сақтау қапы
- Жапсырмалар
- керек-жарақтар
A correct drawing with an inconsistent BOM can still produce the wrong product.
Both documents should be aligned before production release.
Step 10: Confirm Operating Poles, Adapters, and Accessories
Portable earthing set drawings often focus on cables and clamps.
Do not forget the operating equipment.
If the supply includes an insulating operating pole, confirm:
- Полюс түрі
- Fixed, sectional, or telescopic design
- Қажетті жұмыс ұзындығы
- Тиісті жерде жиылған ұзындық
- басшысы түрі
- Қысқыш интерфейсі
- адаптер
- Сақтау қапы
- сан
The most important interface question is:
Does the operating pole actually connect to the selected clamp mechanism?
A correct pole and a correct clamp can still be incompatible if their interfaces differ.
Also confirm other project accessories such as:
- Сақтау орны
- Transport bag
- Қосалқы қысқыштар
- Spare adapters
- Жапсырмалар
- Тексеру тегтері
If these are part of the approved supply scope, they should appear in the drawing package or BOM.
Step 11: Define Marking and Traceability Before Production
Do not wait until FAT to decide how the product will be identified.
The approved technical package should define the required marking system.
Жобаға байланысты, бұл мыналарды қамтуы мүмкін:
- Жиынтық идентификаторы
- Сериялық нөмір
- Кабельді анықтау
- Кабельдің көлденең қимасы
- Кабель ұзындығы
- Clamp ID
- Component number
- Тұтынушы активінің нөмірі
- Batch reference
- Rating reference
- QR коды
- Жобаның атауы
The identification system should connect:
Physical set → production record → drawing → test evidence → FAT record → delivery documents
For lifecycle control, see портативті жерге қосу құрылғыларын сәйкестендіру және бақылау мүмкіндігі.
If markings must appear in specific positions, define them before manufacturing.
Бұл әсіресе келесілер үшін пайдалы:
- Үлкен тапсырыстар
- Multiple kit configurations
- Utility projects
- EPC packages
- Projects with component-level traceability
Step 12: Identify Technical Deviations
A supplier drawing should not hide technical deviations.
Suppose the RFQ requires:
70 мм² мыс өткізгіш.
The supplier drawing shows:
50 мм².
The buyer should not be expected to discover that difference manually without a deviation statement.
Likewise, deviations may include:
- Different clamp model
- Different conductor material
- Different cable length
- Different topology
- Different ferrule
- Different cluster
- Different operating pole
- Different accessories
- Different marking
- Different supporting evidence
A strong technical submittal separates:
Compliant requirement
-дан
Бекітілген балама
-дан
Technical deviation
Every material technical deviation should be declared, not hidden inside a revised drawing.
This makes approval more transparent and protects both buyer and supplier from later disputes.
Step 13: Control Review Comments and Drawing Revisions
Drawing comments should be traceable.
Тек мыналарға ғана сенуден аулақ болыңыз:
- WhatsApp хабарламалары
- Verbal discussions
- Marked screenshots
- Uncontrolled email instructions
For project orders, use a comment register or controlled drawing-markup process.
Мысалға:
| Review Comment | Жеткізушінің жауабы | қайта қарау | мәртебе |
|---|---|---|---|
| Earth lead length does not match approved layout | Revised to project value | Rev.B | Жабық |
| Earth clamp interface unclear | Clamp detail added | Rev.B | Жабық |
| Test report reference missing | Added to technical schedule | Rev.B | Жабық |
| Kit ID location not shown | Marking position added | Rev.C | Жабық |
The purpose is not to create unnecessary paperwork.
It is to make sure:
The factory knows exactly which comments have been incorporated into the production version.
Drawing Approval Status Should Be Clear
Different EPC companies, utilities, and consultants use different approval codes.
A project may use statuses such as:
| Review Status | Типтік мағына |
|---|---|
| Бекітілген | Drawing can proceed under project procedure |
| Approved with comments | Comments must be incorporated as specified |
| Revise and resubmit | Production should not proceed from the submitted version |
| Қабылданбаған | Proposed configuration is not accepted |
The exact terminology should follow the contract.
Do not assume every organization uses the same approval code.
Маңызды мәселе мынада:
The manufacturing team should be able to tell whether the drawing is formally released for production.
A Purchase Order Is Not Automatically a Drawing Approval
This distinction matters for custom equipment.
A buyer may issue the PO first and complete technical submittal approval afterward.
Бұл жағдайда:
Сатып алуға тапсырыс
автоматты түрде мынаны білдірмейді:
Approved for Production
unless the contract specifically says otherwise.
For project-specific portable earthing equipment, a controlled workflow may be:
PO issued
↓
Supplier drawing submitted
↓
Buyer comments
↓
Revised drawing
↓
Техникалық бекіту
↓
Өндірістік шығарылым
This reduces the risk of manufacturing an assembly that later needs to be changed.
When Is a Drawing Ready for Production Release?
Before approving manufacturing, ask:
Is the revision correct?
No open revision conflict.
Does the drawing match the RFQ?
No uncontrolled technical change.
Is the topology correct?
The required current path is clear.
Are all important leads defined?
Cross-section and individual length are shown.
Are clamps matched to real interfaces?
No generic or assumed interface.
Are terminations and cluster defined?
The complete current path is controlled.
Does the evidence support the configuration?
No unexplained gap between tested and offered design.
Does the BOM match the drawing?
No component inconsistency.
Are operating poles and accessories included?
The complete scope is controlled.
Are markings defined?
Traceability can be implemented during manufacturing.
Are all technical deviations approved?
No hidden alternative.
Are review comments closed?
No unresolved technical action.
If these questions cannot be answered, production release may be premature.

Common Drawing Approval Mistakes
Approving From the Product Name Alone
“Three-phase grounding set” does not define the complete assembly.
Reviewing an Obsolete Revision
Production may follow different technical data from the approved version.
Checking Cable Cross-Section but Not Individual Lengths
Correct cable size does not prove correct geometry.
Ignoring Actual Clamp Interfaces
A clamp must match the physical connection point.
Approving Topology Without Checking Site Geometry
A theoretically correct arrangement may still not fit the intended connection points.
Not Comparing the Drawing With Test Evidence
The production configuration may differ from the tested configuration.
Ignoring Ferrules and Terminations
The cable-to-clamp interface is part of the complete current path.
Ignoring the Connecting Cluster
The common point can be part of the supported assembly configuration.
Allowing the BOM to Differ From the Drawing
Manufacturing may follow the wrong component list.
Leaving Operating-Pole Interfaces Undefined
The supplied pole may not fit the clamp mechanism.
Accepting Hidden Technical Deviations
Differences should be declared before approval.
Approving Through Uncontrolled Messages
The factory may not know which revision is final.
Starting Production Before Comments Are Closed
The project may later require rework.
Waiting Until FAT to Discover a Drawing Error
FAT should verify production against an approved drawing, not become the first detailed engineering review.
How We Review a Portable Earthing Set Drawing Before Production
When we prepare a project-specific portable earthing set for production, we review the technical package in a fixed sequence.
We Confirm the Current Drawing Revision
We make sure engineering, production, sales, and the customer are reviewing the same document.
We Compare the Drawing With the Approved RFQ
We check the required fault duty, interfaces, topology, cables, accessories, and documentation.
We Confirm the Connection Topology
We identify the phase and earth current path clearly.
We Check Each Lead Separately
We review conductor material, cross-section, and length for each phase and earth lead.
We Compare the Layout With Site Geometry
We review the approved connection distances and interface information supplied by the customer.
We Match Each Clamp to Its Connection Point
Phase clamps and earth clamps are checked against the actual interface.
We Review Ferrules and the Cluster
The complete current path is reviewed as one assembly.
We Compare the Drawing With Technical Evidence
We check whether the proposed production configuration remains supported by the declared fault-duty evidence.
We Compare the Drawing With the BOM
Component references and quantities should agree.
We Confirm Operating Poles and Accessories
The complete delivery scope is reviewed before release.
We Define Marking and Traceability
Kit IDs and component identification are included in the production requirements where required.
We Record Technical Deviations
Any proposed difference from the approved requirement is made visible.
We Close Review Comments
A revised controlled drawing is issued when technical changes are required.
We Release the Approved Revision to Production
Manufacturing should follow the final controlled document.
After production, the next control point is FAT.

FAQ About Portable Earthing Set Drawing Approval
Should a Portable Earthing Set Drawing Be Approved Before Production?
For custom, project, tender, or technically controlled orders, drawing approval is often an important part of the supplier-submittal process. The exact approval requirement should follow the contract, purchaser specification, and project procedure.
What Should a Portable Earthing Set Drawing Show?
It should identify the complete configuration, including topology, cables, individual lengths, phase clamps, earth clamp, terminations, cluster, operating pole, accessories, relevant technical references, and identification requirements.
Is a Quotation Drawing the Same as an Approved Production Drawing?
Not automatically. A quotation drawing may be preliminary. The production drawing should reflect the final approved technical configuration and controlled revision.
Should the Test-Report Drawing Match the Production Drawing?
The buyer should be able to understand how the available technical evidence relates to the proposed production configuration. Material differences should be declared and reviewed.
Does an Approved Drawing Prove the Fault-Current Rating?
No. The drawing defines the proposed configuration. The declared fault-duty rating still needs suitable supporting technical evidence.
Should Each Cable Length Be Shown Separately?
For multi-lead assemblies, this is good procurement practice because different phase and earth leads may require different lengths.
What Happens if the Supplier Changes a Clamp After Drawing Approval?
The change should be technically reviewed. Depending on the project and significance of the change, a revised drawing, deviation approval, and review of supporting evidence may be required before production continues.
Is a Purchase Order Enough to Start Manufacturing?
That depends on the contract. If technical drawing approval is required, PO issuance should not automatically be treated as production approval.
Сатып алушының практикалық қорытындысы
A portable earthing set drawing should be reviewed as a configuration-control document, not as a product illustration.

The strongest approval chain is:
Approved RFQ → Site and Interface Data → Supplier Drawing → BOM → Technical Evidence → Comment Closure → Approved Revision → Production → FAT
The drawing-review stage is where the buyer can confirm that the factory is about to manufacture the correct assembly.
FAT comes later.
FAT should verify that the finished product matches the approved production drawing.
It should not be the first time the project discovers that the cable lengths, clamps, topology, or BOM were wrong.
