30 amp generator with 12 gauge wire?????
Ok, have a quick question for you electrical guys. I had to pull my Onan 4000 generator for some landing gear work. Noticed that the AC feed wires are 12 gauge and about 6' long before a junction box ...

I believe the wiring in question is part of an engineered system. Engineering calculations determined the wire size and temperature rating of the wire required.
As such the system does not have to comply with NEC requirements.
NEC covers systems that have not been engineered.
Very interesting. Thanks.
What constitutes an engineered system and who is qualified to do such?
