Your wire sizes are right, but weather or not you need a four conductor or three conductor depends on if there are any other metal paths between the two buildings. Phone, water, gas line etc.
Ok, thanks. I thought i had to go with a main Lug and a separate disconnect? Doesnt the ground and Neutral have to be physically seperate in the sub panel, and connect together ONLY in the main panel? If i go with a main Breaker type box, is there a way to isolate the grounds and neutrals??
If i can go with a main breaker type panel, that will make it much easier, as I wont need to have 2 boxes out there.
There is no other metal lines running out to the garage, however
, when I run the power cables, i want to run in separate conduit
, a wire for the alarm system to put the garage on a zone in the main alarm system, and a cat5 cable. Would this be considered a metal path back tot he house??? if so, would this result in a seperate ground rod needed outside the garage? Would I need to ground in both places, or just in one or the other?
Thanks in Advance....
