Letter # 20070926-7973

Re: Whether extension cords may be repaired and returned to use.

Question: Where an extension cord being used in construction has been damaged near the plug end, is it permissible to replace the plug with an approved cord cap made for that type of cord, provided the repair is done by a qualified electrician?

Answer: Extension cords used in construction may be repaired, so long as the repair returns the cord to the "approved" state required by §1926.403(a).
