Reconditioning of electrical equipment is not a new process in the electrical industry, The NEC was silent on this subject prior to the 2017 edition. There, new requirements appeared in Section 110.21 to specifically address reconditioned equipment. The subject of reconditioning continues to evolve as the 2020 NEC development process nears the final stages of the revisions cycle. Many additional rules for the reconditioning of electrical equipment will appear in the 2020 NEC. Most of these rules will clarify which equipment is or isn’t prohibited from being reconditioned. The National Electrical Manufacturers Association (NEMA) has developed a valuable set of guidelines and recommendations that support the new requirements appearing in the NEC on the topic of conditioning.
