In the electrical power sector, ensuring the safe operation of distribution equipment is not just a technical requirement—it’s a matter of life and death. One of the most frequently discussed safety topics is whether it is mandatory to lay insulating rubber mats in front of switchboards or distribution cabinets.

Today, Jinneng Electric Power examines this topic from the perspective of regulations, standards, and best practices to provide clarity for power professionals and facility operators alike.

Is Laying Insulating Mats Legally Required?

When it comes to high- and low-voltage distribution rooms, the installation of insulating rubber mats is not just recommended—it is an industry-wide safety consensus, reinforced by national regulations.

Key standards include:

• GB 26860-2011 — Safety Code for Electric Power Operation in Power Plants and Substations

• GB 50054-2011 — Code for Design of Low-Voltage Distribution Systems

These standards explicitly require insulation measures in areas where operators are exposed to energized equipment, especially in environments with elevated voltage or risk of arc flash.

By laying insulating mats in such locations, companies can:

• Minimize the risk of electric shock and step voltage incidents

• Reduce chances of electrical fires caused by short-circuit arcs

• Provide a controlled, non-conductive surface underfoot to protect workers

Controversy Around Independent Distribution Cabinets

Unlike centralized distribution rooms, independent or isolated distribution cabinets (especially in low-voltage environments) are often installed in corridors, equipment rooms, or utility closets. Whether insulating mats are needed in front of these has been a subject of debate:

• Some argue against it, citing that:

  • The working voltage is relatively low

  • Cabinets are often grounded and enclosed

  • The risk of arc flash or step voltage is reduced

• Others argue in favor, particularly because:

  • Many installations are in damp or high-humidity environments, where insulation becomes critical

  • Even low-voltage faults can cause serious injury during maintenance

  • Mats serve as a preventive layer of protection, aligning with broader safety management systems

Jinneng’s Recommendation: Follow Safety-First Principles

While some applications may fall into regulatory gray areas, Jinneng Electric Power strongly recommends laying insulating mats in all areas where human contact with electrical components is possible—even if the voltage is considered “low.” Our reasoning is based on:

• The evolving nature of electrical safety risk management

• The growing emphasis on human factor engineering and accident prevention

• Real-world data showing that even small oversights can result in injury or legal liability

In addition, Jinneng’s environmentally friendly insulating mats are:

• Easy to install and maintain

• Manufactured in accordance with HG2949-1999 national standards

• Resistant to moisture, aging, and chemical corrosion

• Certified by SGS EU testing for human and environmental safety

Conclusion: Better Safe Than Sorry

While legal mandates exist for high-risk environments, there is still room for professional discretion in lower-voltage setups. However, from a risk management and workplace safety perspective, laying insulating rubber mats is a proactive and cost-effective safeguard—especially when the consequences of electrical accidents can be severe.

At Jinneng Electric Power, we believe in going beyond compliance to provide durable, certified, and user-friendly safety products that empower frontline electrical workers and reduce risk across every application scenario.
