Second sub panel and conduit question
Hi all,
New to this forum and finding lots of great advice. I'm planning on adding a 100A sub panel to my garage workshop.
The house has 200A service and the main panel is located in the garage. The plan is to use a 125A main lug panel fed by two #2 copper for the hot feeder legs, a #6 copper neutral, and a #6 or #8 copper ground. Does this sound appropriate?
The sub will be located one stud bay away from the main (16") so would it be best to run the wiring through conduit as opposed to cable (which I assume would have to be covered with drywall)?
Lastly, the house is already wired for a 100A sub panel in the basement. Does code permit another 100A sub in the garage? The basement is currently unfinished, but even if I finish it, I don't anticipate using all of the circuits in the house, basement and garage at the same time.
I did a bit more reading and realized it might help to state that the house is a 2000sf single family residence, 1 level ranch. Standard household appliances with A/C and forced hot air heating. If I finish the basement it will have standard lighting fixtures, and outlets - no hot tubs or anything exotic.
I did look at the NEC 2005 to try and determine amp load for this size residence, but it's very confusing.
Thanks in advance for any advice...
