Dedicated Electrical

I use one direct run of Romex 8/2. I found it easier to handle as it’s stranded compared to the 10 gauge solid conductors. The wire wasn’t too thick and fitted into 20amp hospital grade receptacles.

Excellent choice.

Same box is fine.

Question is which bar. There are two to chose from.

Use the one with the least major appliances-a/c, etc.

Then look at the ground and try to improve it. 

Buy some Furatech, Pangea or better receptacles.

I ran two 20 amp dedicated lines on 12/2. Seems fine.

Spent $300 on the whole deal.

Thanks guys!

Well, depends on the distance and circuits. If it's a long run and you are planning multiple circuits a sub panel is the way to go.  The voltage drop / foot will be smaller.
