Inspected an FPE panel where all of the branch wires are aluminum. Explained the problems with the electrical system and recommended inspection/upgrades/repairs as deemed appropriate by a licensed electrician.
Knowing from expereince that one must educate the client and provide them with any written documents if possible before the “expert” shows up to contradict everything I say, I informed them about the problems with FPE panels and backed up my explanation with Doug Hansens great information.
I then provided the client with an article about aluminum wiring and talked about likely repair options the electrician will recommend. They asked me about the costs of such so I called my trusty master electrician for a ballpark price. Learned something new! He informed me that an easier fix (and less costly since the FPE has to go) to crimping copper to the aluminum at the end-user points is to leave the aluminum wiring as is and install arc-fault breakers in the panel. If and when an aluminum circuit/outlet/switch decides to act up, the AFB will trip and then the client will know they have a problematic circuit that needs attention. The AFBs will provide the protection they need until which time attention is needed.
I like this recommendation as well when responding to the comment, “the FPE and aluminum wiring have been working for 30 years so why is it all the sudden a problem?”
Anyway, the electrician’s suggestion sounds like a good solution to me. Any thoughts?
