I think I might just go copper. I found a pretty cheap source. The 3-3-3-5 Copper is only about a dollar more per foot than the 6-6-6-6 copper, so I might just go with the 100A service and be done with it.

1/2 the cost of what? I need 4 AL for 60A or 1 AL for 100A. Where does 2 AL fit in? Let's talk workability. Would 6 Cu be easier or harder to work with than 4 AL? What about 3 Cu vs 1 AL? Conventional wisdom suggests that the smaller wire would be be easier but then I hear people say that...

Okay, I think I'm starting to settle on a 60A sub. Should that be enough to serve a Millermatic 211, 220v air compressor, 30A RV hookup (110V), and some misc 20A circuits for feeding power tools. The welder/air compressor plug(s) would be 50A for anything I might want to plug in. Sent from my...

That was my thought. Isn't NM-b cable always rated using the 60*C column? Sent from my SM-G935V using Tapatalk

Pure NEC 2014. No amendments. He called back. Admitted he was wrong. Said it was fine in without conduit and 75*C was okay too. Pretty nice guy. Offered to come and check it out whenever I wanted instead of waiting till the end. Also said to call him anytime with questions. So it sounds like...

Thanks for that. Want to hear something disturbing? City inspector just called me back. Did some discussion, he was helpful for the most part. Now for the disturbing part. He told me that if I use SER cable it must be run in conduit and it must use the 60*C column for ampacity, even if not on...

Interesting, thanks for the info. I think the bordering wall I would come through into the garage is insulated, so I might still be on the hook for 60*C. Unless i punch through BELOW the insulation? Found some other websites that say that it seems like it would be up to the inspector on what...

Interesting idea. I have a call in to the city inspector to see what they will/won't allow in a situation such as mine. EDIT: Did a quick google search. In the few places where I could find prices, looks like 2AWG Teck cable runs in excess of $11/ft. Isn't 2-2-2-4 aluminum good for 90A in...

Long time lurker, need some help. Just bought a new house and want to add a subpanel in the garage. I've been scouring the internet but can't find a lot of help because I feel like I've got some interesting design challenges. Let's get the basics out of the way first. 200A main panel (at...
