    (USA) 4/0 SER from Meter to Disconnect

    Just got here, and I'm not sure if this question will make sense to UK folks, or if there are any USA folks here at all. Anyway: due to supply issues, I can't find any 4/0 XHHN or THHN. I'm trying to connect my meter to a 200 amp disconnect. Can I use 4/0-4/0-4/0-2/0 alumin(i)um SER cable for...

    Exterior conduit in hot, high humidity/wet geographic locations

    I've lived and worked my entire life in SoCal. Recently we moved to Southern Texas where there is a lot of rain (from a SoCal perspective) and constant high humidity. For exterior building runs, I mostly see PVC instead of EMT. Is this just people being cheap? Or should EMT be avoided in...

    How high must a electric service line be

    There is a 220 volt electric service line crossing my empty sloped lot going to a neighbor's house. Neither the power company nor my neighbor have a written type of easement across my yard for this line. Many years ago the power company just put it there because it was easy to do. It was 15...

    220 volts ran through one hot wire

    I recently tore down all the wiring in my grandfather’s garage he wired himself and i’m genuinely surprised it didn’t burn to the ground after 40+ years, but there’s some things I need some help with. He’s long gone so that’s that. First off, he only had 1 hot wire supplying 220v to his air...
