I need to have an “aluminum wire survey” done on 2 buildings I own in NJ. can someone tell me what that means?
Camlawnman is correct regardless of the thumbs down. Not only is aluminum wire “not preferred”, it is illegal to install. Well, illegal to the NEC. Existing aluminum wire however is allowed (grandfather clause). The aluminum wire survey must be conducted by a qualified electrician (likely one they will provide or approve) so that one couldn’t have their electrician friend come up and say “yup, all copper” even if there was aluminum in the building.
