I have a question for an Electrical Engineer
I want to run 100 amp 220V to a detached Garage, it is approx 80 feet between service entrance and fuse box in the Garage…
what size wire do I need;
I prefer Copper
of course aluminum would be cheaper, but I’ll buy Copper wire. and install in gray plastic
last question; it needs to have a ground rod at the garage also ?
I called the Power Company Engineering Dept, they no longer (provide/advise) the needed wire size !
thanks in advance
