I'm moving this month and need to install a sub panel in the small garage located at the new place. I'm planning on a 100 amp panel that's located about 120' from the 200 amp main box. The stove, water heater, boiler, and dryer all run on natural gas so I have plenty of juice. I have more than enough 2" schedule 40 conduit for the whole run including the inside stuff. I'm kinda having a hard time deciding which wire to run. I've been cramming on nec stuff lately and I'm still kinda confused. I'm thinking 3 individual #1 copper thhn wire and one #3 for a ground. This sound right to you guys? I'm sure there's a couple people on here that are knowledgeable in electrical work and nec codes. I'm looking to do it myself because I may go into the electrical field soon. Need a change in career and it seems like a good way to go.
