Converting Garage

Greetings!

I am in the process of converting my garage to a workshop. Unfortunately, I have only outlet. Actually two, but the one on the ceiling for the opener doesn't really count. I also have incandescent light.

I have an existing 200amp box with 4 full slots left. It is located in the basement and my garage is attached and I would say my Main is about 20 ft. away from the garage. So the runs would be fairly easy from a subpanel.

I am fairly new to running wiring, but I believe competent.

My needs will be a dedicated circuit for a lightweight table saw
router, sander and some assorted power tools.

I really don't have any plans or the need for a 220 circuit(s).

I am looking for recommendations on size of subpanel I should use?

What type of wire to run from main to sub?

What size breaker for would I use for the main to jumper to the sub?

Would 12/2 romex be sufficient for about 6~8 outlets?

thanks in advance!!

 

I don't think you need a subpanel at all. A couple of 20-amp circuits on two 12/2 cables should provide all you need.

If you really do want the subpanel anyway (perhaps you've always wanted to wire one), then put in 8/3 to a 40-amp double-pole breaker in the main panel. Use a 12-space panel rated for 100 or 125 amps.

Yes, 12/2 is fine for 6-8 outlets.

Be sure to read a few good books on home wiring before you start. There are a million other important details.
