Question:
Hello CQD, does the code allow meter sockets, panels, and breakers to be reused for temporary service power? The equipment is in good shape. Sincerely, Kyle Simmons
A
Answer:
Hello Kyle, good question. Section 590.8 provides guidance on the reuse of Overcurrent Protection Devices - “Where overcurrent protective devices that have been previously used are installed in a temporary installation, these overcurrent protective devices shall be examined to ensure these devices have been properly installed, properly maintained, and there is no evidence of impending failure”.
Additionally, Section 590.2(A) requires Temporary Installations to comply with ALL other Articles of the NEC®, unless specifically modified by Article 590. The reused meter socket and panel must comply with any applicable NEC® requirements. Another resource would be NECA 200-2016, Recommended Practice for Installing and Maintaining Temporary Electrical Power at Construction Sites.
On a side note the 2023 edition of the NEC® has a new Section 240.2(A)-(B) that addresses reconditioning of overcurrent protection devices. Molded case circuit breakers are not permitted to be reconditioned.
