power socket questions

[ratman2]

Hey guys,
For a 656 sq. ft. garage how many 110V sockets should I have and what size breaker should they be on? I also have a welder that uses a 220V NEMA 50-R plug and for this I'm thinking 2 sockets on the same circuit, one at each end of the garage. Other thoughts?

Outlets should be on 20A breakers, spaced every 4', and installed 4.5'-high so a 4' sheet of plywood/drywall will not block them. 2-gang boxes near the workbench. There should be at least 2 convenience outlet circuits in a garage that size.

Consider a dedicated compressor circuit and heat/AC circuit. I installed 6/3 wire for my 50A welder circuit to support an oven for powder-coating.

To put a outlet every 4' along the wall is going to be tough due to the amount of shelving that's going to be in the garage. Right now my thoughts are to put some more sockets in the ceiling and mount extension cord reels up there. I do have a compressor but am not sure whether I'm going to get a new one with a vertical tank that can take up less floor space. Heat is going to be propane and as of right now no AC.

Be sure you don't exceed 8 outlets per circuit. It's not a bad idea to start each circuit with a GFCI to protect you and anyone else that may happen to use power in the event that water happens. Just be sure to wire the additional outlets so they are "protected" by your GFCI.

Another thought is wherever you can put an outlet put in a double-gang box. (2 duplex outlets) You could even wire it so these outlets are on separate circuits.

why not exceed 8 outlets per circuit?

GFCI protection is not just a good idea, its mandatory for receptacles in a garage- no exceptions.

Yup - sure is. I have 2 big power strips that will be going along the wall.
