Infrared thermography allows technicians to detect heat anomalies in electrical components such as panels, breakers, switchgear, and connections. These heat patterns often indicate underlying issues like loose connections, overloaded circuits, or failing components.

Under NFPA 70B guidelines, thermographic inspections are no longer optional—they are considered a critical component of maintaining electrical system reliability and safety.

Key Thermography Requirements

NFPA 70B outlines several important considerations for implementing thermographic inspections effectively:

• Regular inspection intervals based on equipment condition and criticality
• Proper documentation and reporting of thermal anomalies
• Immediate corrective action for identified issues
• Use of qualified personnel to perform and interpret inspections

These requirements ensure that infrared inspections are not only performed, but also used as actionable tools for preventing failures.

Compliance and Risk Reduction

Following NFPA 70B thermography requirements helps organizations reduce the risk of unexpected equipment failure, electrical fires, and costly downtime. It also supports compliance efforts and demonstrates a commitment to safety and reliability.

For many industries, especially those with mission-critical operations, adhering to these standards is becoming a necessity rather than a recommendation.
