Why Infrared Thermography is Essential for NFPA 70B Compliance in Commercial and Industrial Facilities

What is NFPA 70B and Why Is It Important?

In 2023, NFPA 70B underwent a major revision that transformed it from a recommended guideline into a mandatory standard for electrical preventive maintenance. This change has significant implications for facilities with energized equipment, particularly in manufacturing, data centers, healthcare, and commercial real estate.

Facilities are now required to implement Condition-Based Maintenance (CBM) strategies for electrical systems — moving away from purely time-based or reactive approaches. The goal? Improve reliability, reduce downtime, and minimize fire and electrical hazards before they cause catastrophic losses.

Infrared Thermography NFPA 70B: The Heart of Condition-Based Maintenance

At the core of NFPA 70B’s new requirements is infrared thermography — a proven, non-intrusive method of identifying electrical risks before they become failures.

With IR imaging, our certified technicians at Assured NDT can detect:

• Loose or corroded electrical connections

• Overloaded circuits and imbalanced loads

• Deteriorating insulation or breakers

• Hot spots and hidden faults invisible to the naked eye

These insights allow facility managers to prioritize repairs, reduce unplanned outages, and extend the lifespan of critical systems — all while staying in full compliance with national codes.

Avoid Downtime and Costly Repairs

Failure to comply with NFPA 70B isn’t just a regulatory risk — it’s a business risk.

According to the NFPA and IEEE, facilities that implement routine thermographic inspections see:

• Up to 80% fewer electrical failures

• Significantly reduced fire/explosion incidents

• Lower insurance premiums and fewer claims

With typical inspection costs ranging from $1,500–$10,000 per year per facility, it’s a high-ROI investment that protects your assets, people, and bottom line.

Who Should Act Now?

If your facility includes:

• Electrical panels or switchgear

• Motor control centers

• Transformers or substations

• Generators or backup power systems

then NFPA 70B applies to you, and infrared thermography should be part of your annual maintenance plan.
