The Importance of NFPA 70B for Commercial Buildings
For facility managers and property managers, electrical systems are often out of sight and out of mind — until something goes wrong. A failed breaker, overheated connection, unexpected shutdown, or power outage can quickly disrupt tenants, operations, productivity, and safety.
That is why the growing importance of the National Fire Protection Association standard known as NFPA 70B is getting more attention across the commercial property industry.
At MEC Electrical & Technologies, our electrical service department helps facility managers and property managers stay ahead of electrical failures through preventative maintenance, inspections, troubleshooting, and long-term electrical system support.
What Is NFPA 70B?
NFPA 70B is the standard for electrical equipment maintenance. It provides guidelines and best practices for maintaining electrical systems to improve safety, reliability, and performance.
Historically viewed as a recommended practice, NFPA 70B has evolved into a much more significant standard for building owners, facility teams, and contractors. The focus is simple: electrical systems require routine maintenance to remain safe and dependable.
Just like HVAC systems, roofs, elevators, and fire protection systems need regular service, electrical infrastructure also needs preventative maintenance to reduce the risk of failures and hazards.
Why Preventative Electrical Maintenance Matters
Many electrical issues develop slowly over time without obvious warning signs. Loose connections, overloaded circuits, aging equipment, moisture intrusion, corrosion, and thermal stress can all lead to serious problems if left unchecked.
Without proper maintenance, facilities may experience:
- Unexpected equipment failures
- Costly downtime
- Tenant complaints
- Production interruptions
- Arc flash hazards
- Increased fire risks
- Shortened equipment lifespan
- Emergency repair costs
Preventative electrical maintenance helps identify small issues before they become major failures.
For commercial properties, industrial facilities, office buildings, warehouses, retail spaces, and multi-tenant buildings throughout Massachusetts and New England, proactive maintenance can save significant time and money while improving operational reliability.
How Our Electrical Service Department Helps
Our service team works directly with facility managers and property managers to create practical maintenance solutions that fit each building’s operations and budget.
We help clients with:

We help identify potential code concerns and safety risks while providing practical recommendations for upgrades or repairs.
Long-Term Facility Support
Our goal is not just to respond to emergencies — it is to become a trusted electrical partner that helps keep your building powered, operational, and safe year-round.
The Cost of Waiting Until Failure
One of the biggest misconceptions in commercial facilities is that if electrical equipment is still running, it must be fine.
In reality, many failures happen after years of hidden deterioration. By the time visible symptoms appear, the damage may already be significant.
Unexpected shutdowns can impact:
- Tenant satisfaction
- Business operations
- Revenue
- Safety
- Insurance exposure
- Equipment replacement costs
A proactive maintenance strategy built around NFPA 70B principles helps reduce those risks and improves overall system reliability.
