Does Your Switchgear Pass Modern Safety Standards? Here’s How to Find Out
Many industrial facilities in Wenzhou operate with switchgear that was installed 20, 30, or even 40 years ago—equipment that may have met safety standards at the time but no longer complies with today’s regulations. While these systems may still function, outdated gear combined with modern electrical loads and safety expectations creates significant risk.
Common Misconception: Operational ≠ Compliant
A functioning switchgear does not necessarily mean it is safe or compliant. In fact, any modification—such as installing a new breaker, replacing a relay, or upgrading control logic—can invalidate the original UL or NRTL certification. According to IEEE C37.59, any change affecting design, clearances, or safety requires re-verification and updated documentation.
Meanwhile, standards from OSHA, the NEC, and NFPA 70E are regularly updated and now require:
-
Verified arc flash studies
-
Updated hazard labels and boundaries
-
Documented maintenance of protective devices
-
Records of employee safety training and PPE policies
Failing to meet these standards may lead to:
-
OSHA violations and fines
-
Denied insurance claims
-
Increased liability for injuries and outages
-
Delays in inspections or permit approvals

Frequently Asked Questions
Is my switchgear OSHA compliant?
That depends on its condition, documentation, and retrofit history. OSHA 1910 requires arc flash labeling, hazard training, and operational safety procedures. Our team will assess your system and provide a clear roadmap to compliance.
What standards apply to medium voltage switchgear?
The most relevant are IEEE C37.20, IEEE C37.59, NFPA 70E, NEC Article 110, and OSHA 1910 Subpart S. These cover equipment design, testing, labeling, and safe work practices.
How can I test old gear against modern standards?
Testing involves insulation resistance, contact resistance, mechanical timing, and racking force. We combine field diagnostics with engineering review to determine retrofit needs.
Can I add breakers without voiding certifications?
Only if done through a manufacturer-approved process with UL/NRTL verification. Otherwise, original certifications are voided. We help maintain or restore certifications during upgrades.
Why is IEEE C37.59 important?
This standard outlines how modified switchgear must be design-tested and documented to remain compliant. It is essential for ensuring electrical safety, maintaining insurance coverage, and preserving UL certification.
