National Fire Protection Association News

Since 1975, the National Fire Protection Association has published NFPA 70B, Recommended Practice for Electrical Equipment Maintenance.  Over time this comprehensive document has evolved to cover a wide array of testing and maintenance practices for installed electrical equipment.  The past several editions of 70B have recommended that infrared inspections of energized electrical equipment be performed annually.


On January 16, 2023, this document was reissued as NFPA 70B, Standard for Electrical Equipment Maintenance. Compared to previous editions, the 2023 edition of 70B has been updated and extensively revised.  Of particular note is the requirement that infrared inspections are now required on an annual basis for all electrical equipment.  Under certain circumstances, more frequent inspections are required.  


Similar to previous editions, NFPA 70B does not provide specifics for conducting infrared inspections. Such information may continue to be found in the Infraspection Institute  Standard for Infrared Inspection of Electrical Systems and Rotating Equipment.


Infraspection Institute have long recognized the value of thermography as a tool for electrical system maintenance.  We commend NFPA for the latest edition of 70B and their continued efforts to help ensure public safety.
