Size Wire for 100 Amp Garage Sub-panel
Asked Jan 19, 2012, 11:03 AM
What type and size wire, in PVC conduit, for 100 amp 120/240 volt sub-panel in free standing garage/workshop 120 feet from main panel? I assume 1/0 aluminum will be cheaper than #1 copper and ground must insulated. What size ground. What size conduit? Will 2" conduit be worth the additional cost over 1 1/2' as far as pulling? What would be trade name for wire, if any. Must neutral be white or can it be redesiginated with paint.
I have done my own research but would like to have confirmation.
