What Is NFPA 70B and Why It Matters
NFPA 70B is a critical standard developed by the National Fire Protection Association (NFPA) that focuses on electrical equipment maintenance. It provides detailed guidance on how to properly maintain electrical systems to prevent failures, reduce risk, and improve safety.
In recent updates, NFPA 70B has transitioned from a recommended practice to an enforceable standard, making it more important than ever for organizations to comply.
Recent updates emphasize:
-
Preventive maintenance programs
-
Routine inspection schedules
-
Use of infrared thermography to detect failures early
For many facilities, annual infrared inspections are now expected as part of compliance and insurance requirements.

Overview of NFPA 70B Standard
NFPA 70B outlines best practices for:
-
Preventive maintenance programs
-
Inspection schedules
-
Testing procedures
-
Documentation standards
Its goal is simple: Reduce electrical failures and improve system reliability
Transition from Recommended Practice to Standard
One of the biggest shifts in NFPA 70B is its evolution into a formal standard.
This means:
-
Increased enforcement potential
-
Greater legal and insurance implications
-
Higher expectations for maintenance documentation
Companies that ignore this shift risk liability, downtime, and compliance issues.
Who Needs NFPA 70B Infrared Inspections?
Our services are designed for facilities that rely on complex electrical systems
How Assured NDT Helps You Meet NFPA 70B
Assured NDT helps companies meet NFPA 70B requirements through comprehensive inspection, testing, and predictive maintenance solutions. Using advanced infrared thermography, we identify issues such as overheating components, loose connections, and potential failures before they lead to costly downtime. Our electrical testing services—including circuit breaker testing, transformer diagnostics, and insulation testing—are designed to ensure system reliability and compliance with NFPA 70B standards. By implementing proactive predictive maintenance programs, we help extend equipment life, improve safety, and keep your operations running efficiently while maintaining full compliance.
Our infrared thermography inspections cover critical electrical components, including:
-
Main distribution panels
-
Switchgear and transformers
-
Motor control centers (MCCs)
-
Breakers and disconnects
-
Electrical connections and terminations
We focus on identifying heat anomalies that indicate potential failure points.
