Why Most Switchgear Upgrade Quotes Miss the Mark — and How to Do It Right
When it comes to upgrading medium voltage switchgear, not all quotes are created equal. In fact, many proposals from general contractors or testing firms lack critical components—such as proper engineering design, compliance verification, certified testing, and long-term reliability. These omissions can result in costly overruns, installation delays, and worse—equipment that doesn’t meet safety standards and puts personnel and infrastructure at risk.
⚠️ The Problem: NEC Alone Isn’t Enough
Most contractors and electrical service providers base their switchgear upgrade approach on the National Electrical Code (NEC). While NEC outlines general installation rules, it doesn’t cover the specialized engineering and testing required for retrofitting medium voltage switchgear. Proper upgrades must align with IEEE standards and be certified by a Nationally Recognized Testing Laboratory (NRTL). Only manufacturers and their authorized partners—like GONGSHUN Electric—have the training and certification to meet these high standards.
Contractors, even experienced ones, typically aren’t authorized to certify that a retrofit complies with IEEE design requirements or NRTL testing protocols. As a result, quotes from these sources often skip over critical compliance elements.
🚩 A Red Flag: Oversimplified Quotes
One of the most common warning signs is a quote that only includes the cost of a replacement breaker and labor—without checking whether the breaker is even compatible with your existing switchgear. These quotes often ignore vital factors like:
- Compartment and mechanical interface compatibility
- Racking mechanism integration
- Arc flash hazard re-evaluation
- UL or NRTL listing requirements
These omissions can result in incomplete, unsafe, or non-compliant installations.
🚫 “Arc-Resistant” – In Name Only?
Even more concerning are quotes that advertise “arc-resistant upgrades” without referencing IEEE C37.20.7 arc flash type testing. Genuine arc-resistant gear must undergo full-scale testing at an NRTL facility. If a quote makes these claims without test data, it’s not just misleading—it’s dangerous.
✅ What Should a Proper Switchgear Upgrade Quote Include?
A compliant, complete quote should cover:
- Engineering design and verification
- Compatibility review
- Documentation
- Testing and inspection
- NRTL certification coordination
GONGSHUN Electric includes all of these in our turnkey solutions, so you don’t end up paying for mistakes down the road.
Frequently Asked Questions
🔧 Should a retrofit include design verification?
Absolutely. IEEE C37.59 mandates it. Without proper design validation, the upgrade cannot be considered compliant—even if it appears to function properly.
🛠️ What’s typically missing from standard quotes?
Key components like design validation, arc flash analysis, third-party certification, and field documentation. GONGSHUN Electric includes them all.
💰 How much does a compliant upgrade cost?
It varies by equipment type, breaker model, footprint, and applicable standards. While our quotes may not be the lowest, they reflect fully compliant, safe, and long-lasting solutions—not quick fixes that cost more in the long term.
⚡ Outdated Doesn’t Mean Safe
Many facilities still operate switchgear that’s 20–40 years old. While it may still function, these systems likely fall short of today’s safety and regulatory standards. Modifying or adding components—like breakers or relays—can void your gear’s original UL or NRTL certification.
Under IEEE C37.59, any upgrade affecting clearances, insulation, or safety functions requires fresh engineering review and updated documentation.
📜 Evolving Safety Standards
Modern compliance requirements from OSHA, NEC, and NFPA 70E demand:
- Verified arc flash studies
- Updated labeling and hazard zones
- Maintenance records for protective devices
- Proof of employee training and PPE protocols
Failure to comply can result in:
- OSHA fines and violations
- Denied insurance claims
- Increased liability exposure
- Inspection and permitting delays
🧩 How GONGSHUN Electric Helps
Our engineers and field technicians provide full audits and compliance assessments. We review:
- Existing gear and any prior modifications
- UL/NRTL certification status
- Breaker compatibility and insulation performance
- Arc flash labels and hazard boundaries
Then we deliver a prioritized action plan to bring your system up to code.
Key Questions Answered
Is my gear OSHA-compliant?
It depends on current condition, documentation, and retrofit history. We audit your gear and provide a clear compliance roadmap aligned with OSHA 1910 Subpart S.
What standards apply to MV switchgear?
Relevant codes include IEEE C37.20, IEEE C37.59, NEC Article 110, and NFPA 70E. These govern design, labeling, testing, and worker safety.
How is old gear tested?
Testing includes contact resistance, insulation, mechanical racking forces, and timing. We combine these results with engineering evaluations to guide retrofit decisions.
Can I add breakers without voiding certification?
Only when the process is backed by the original manufacturer and includes UL/NRTL re-verification. Otherwise, certification is void—and safety and liability are compromised.
✅ Don’t Settle for Incomplete Quotes
A functioning switchgear system is not automatically a compliant one. Ensure your upgrades are engineered, tested, and certified to meet modern safety expectations.
