Garage circuit breaker box advice needed

[xcmountain80]

It certainly can be explained over the internet, as electricians have to read their material somewhere as well and for God's sake let no glorify the heck out of electricians as I've met a few that I'm certain I out qualify. Nullifier, please take my advice as a CGC and not an expo member. If you were looking to jump your box to the next size or one after that I'd say knock yourself out. But for the amount of load you are planning on placing I would recommend calling a licensed electrician. You will likely need a new line run as the one currently coming in will most likely be to small to carry what your looking for. You might find the route you want to run cost preventative and may have to scale down your box ambitions. But at least call and have them come out and give you a price, you can always say no. Hell you can always offer to have them do it outside their normal business hours.......

For anyone considering doing their own electrical wiring, I recommend this book.
Rex Cauldwell "Wiring a House" published by The Taunton Press as part of their "For Pros by Pros" series of books.

Easy to read, well illustrated. Discusses minimum code requirements and how to improve an electrical layout.

FWIW, I remodeled my kitchen a few years back - which entailed adding a subpanel in the garage. I hired an electrical contractor to review the plan, assist with a material list. I did the bulk of the work; pulling wire, making up the individual boxes (receptacles, switches, lighting fixtures, etc.) When I was done with the grunt work, the electrician returned to connect everything at the subpanel.

Just make sure any book you reference wasn't amongst those recently recalled....

Home owner electricians :Wow1:

Made a lot of money fixing their mistakes though.
As for a 220 volt circuit on a two wire, NMB or romex is listed per size of conductors and number of insulated conductors. 10/2 NMB has 1 #10 Black, 1 #10 White, and 1 #10 Bare.
