Your electrical system is humming along quietly right now—panels powering your building, circuits delivering electricity to every corner of your facility. Everything seems fine. Your equipment is running. Lights are on. No problems to see here.
But here’s the catch: most electrical system failures don’t announce themselves in advance. They develop silently over months or years—loose connections generating heat, corrosion eating away at components, insulation gradually degrading—until the day something fails.
And when it does? It’s usually at the worst possible time.
For facility managers and property owners across Vermont, the solution isn’t to wait for failure. It’s to implement a preventative maintenance program based on NFPA 70B—the national standard for electrical equipment maintenance.
At Cummings Electric, we work with commercial buildings, healthcare facilities, industrial properties, and multi-site portfolios to implement NFPA 70B programs that prevent emergencies, protect people, and keep operations running smoothly.
Here’s what you need to know.
What Is NFPA 70B?
NFPA 70B is the national standard for electrical equipment maintenance. While the National Electrical Code (NEC) covers how systems are installed, NFPA 70B covers how they’re maintained safely over time.
It establishes guidelines for inspection schedules, testing methods, maintenance practices, and documentation. For Vermont facility managers, it provides a proven framework to keep systems safe, code-compliant, and reliable.
Why Electrical Maintenance Matters
Here’s what happens when maintenance is neglected: problems develop silently—loose connections creating heat, corrosion, degraded insulation, overloaded circuits—until something fails.
🔥 Safety & Fire Risk
Electrical fires don’t happen to brand new systems. They happen when problems have been developing undetected. Regular inspections with infrared cameras catch heat patterns that are invisible to the human eye, catching problems before they become fires.
⏸️ Downtime & Emergency Costs
An unexpected electrical failure hits at the worst time. One hour of downtime can cost:
- Manufacturing: $10,000-$100,000+ in lost production
- Healthcare: Critical equipment down, patient safety at risk
- Emergency repairs: 5-10x more expensive than scheduled maintenance
One prevented emergency pays for years of preventative maintenance.
📋 Insurance & Compliance
Insurance companies expect documented maintenance programs. Without inspection records, claim denials are common. A documented NFPA 70B program proves due diligence to insurers, regulators, and protects you legally if an incident occurs. You may also qualify for 5-15% premium discounts.
What Does NFPA 70B Maintenance Include?
A comprehensive NFPA 70B program includes:
- Visual Inspections: Checking for corrosion, loose connections, overheating, and missing documentation
- Infrared Thermography: Thermal imaging that detects heat patterns revealing loose connections, overloaded circuits, and failing equipment
- Electrical Testing: Insulation resistance, breaker functionality, ground continuity, load balancing, and torque testing to verify system safety
- Equipment Cleaning: Removing dust and debris from panels to improve cooling and reduce fire risk
- Documentation: Detailed records of all inspections, tests, repairs, and maintenance—proof of due diligence for insurers and regulators
Documentation is critical. Your maintenance records prove to insurers, fire marshals, and regulators that you’re maintaining your system properly.
The Business Case
Annual preventative maintenance cost: $3,000-$8,000
Single emergency electrical repair: $5,000-$50,000+ (plus downtime costs)
One hour of unplanned downtime: Often exceeds annual maintenance costs
One prevented emergency = years of maintenance paid for. Add in insurance discounts (5-15%), extended equipment life, reduced liability, and regulatory compliance, and preventative maintenance becomes one of the smartest investments a facility manager can make.
Getting Started
Ready to implement NFPA 70B at your Vermont facility? The process is simple:
- Assessment: We evaluate your electrical systems and identify where maintenance would have the biggest impact
- Plan: We develop a customized maintenance schedule based on your facility type and needs
- Execute: We perform regular inspections, testing, and repairs on your schedule
- Document: We maintain comprehensive records for insurers and regulators
The Bottom Line
Your electrical system is critical infrastructure. When everything is working fine, it’s easy to ignore. But that’s exactly when problems are developing silently.
NFPA 70B preventative maintenance catches those problems before they become emergencies. For Vermont businesses, the benefits are clear:
- ✔ Safety: Reduced fire risk and electrical hazards
- ✔ Reliability: Fewer unexpected failures and downtime
- ✔ Cost Savings: Lower repair bills and insurance premiums
- ✔ Compliance: Documentation for regulators and insurers
- ✔ Peace of Mind: Systems that are safe and well-maintained
Cummings Electric can help you implement and maintain an NFPA 70B program that protects your operations and bottom line.
