In a significant move to enhance the safety, efficiency, and longevity of its commercial industrial, institutional and large residential buildings, NJ instituted a code requirement outlined in the NFPA 70B, which includes mandatory infrared testing as part of its electrical safety and maintenance recommendations.
In 2023, NFPA 70B* mandated annual inspections for ALL electrical equipment, with thermographic inspections and reporting every six months for equipment needing urgent actions identified in prior scans and other specified situations. The mandate also requires that inspections and reporting be done by qualified personnel.
Infrared thermography is a testing method that uses thermal imaging to detect anomalies and deficiencies that are not visible to the naked eye. These anomalies often indicate underlying issues such as moisture intrusion, electrical faults, insulation gaps, and structural defects. By identifying these problems early, property owners and managers can take corrective actions before they escalate into hazardous conditions or costly repairs. This advanced technology has become vital in safeguarding many built environments and in optimizing operational performance.
Key aspects of the code requirement stipulates that all buildings undergo infrared testing at several critical stages: Pre-construction Assessment, Post-construction Inspection, and Routine Maintenance Checks:
To ensure compliance with the new code, New Jersey has outlined protocols for conducting infrared testing which include:
Certification of Inspectors: Only certified infrared thermographers are authorized to perform the inspections. This guarantees that the testing is conducted by professionals with the necessary expertise and experience.
Documentation and Reporting: Detailed reports of the infrared inspections must be submitted to the relevant state authorities. These reports should include thermal images, analysis of findings, and recommendations for any necessary remedial actions.
Follow-up Actions: In cases where anomalies are detected, property owners are required to address the issues within a specified timeframe and undergo re-inspection to confirm that the problems have been resolved.
This comprehensive approach should be applied at the most optimal times. For instance, testing air conditioning and refrigeration systems is most effective during the warmest months. In plants and manufacturing facilities, testing is best conducted during full production days. Conversely, data centers, warehouses, office buildings and retail can be tested any time of the year.
Inspection of your electrical equipment is required at least every 12 months to prevent electrical equipment failures that could result in hazards such as fires, explosions, or electric shock. Early detection of potential issues can significantly reduce costs associated with major repairs and operational interruptions later. Of course, maintaining a safe and well-functioning building will enhance its overall value and appeal.

NFPA 70B, titled “Recommended Practice for Electrical Equipment Maintenance,” is a standard published by the National Fire Protection Association (NFPA). This document provides guidelines and best practices for the maintenance of electrical equipment to ensure safety, reliability, and efficiency in its operation. NFPA 70B covers maintenance procedures for electrical systems and equipment used in industrial, commercial, and institutional facilities. It includes recommendations for routine inspections, testing, and servicing. Learn More – NFPA 70B
