How many 220v outlets do you guys have in your garages?

I am contemplating putting 2 in (currently refinishing the garage in the house I just bought) on opposite sides of my 2.5 car garage so that I can plug my welder in easily no matter which side of the garage I am on.

Any thoughts?

I've got 7, wasn't sure were stuff was gonna live so I added extra. Even put one at 8' so I wasn't tripping over the lift power cord(future).

If you can swing the price of the extra wire, put in extra recepticles, you won't regret it.

I need 3, but can only afford 2, so that's what I'm working on for mine at the moment. I'd have 10 if I could.

If you're refinishing the garage now you might as well spring for about 2 on each wall.

Are they all on separate circuits or on sharing circuits? I have heard that each 220v outlet has to be on it's own separate circuit as per code. I am not sure whether or not that is true, maybe someone can confirm or deny?

There is nothing I can recall in the NEC code that prohibits more than one outlet per circuit AKA a multi-outlet branch circuit. The only restriction I'm aware of is that you HAVE to use more than one outlet (yoke) with a 15 amp outlet on a 20 amp circuit.

as far as multiple outlets on one circuit, it doesnt have anything to do with voltage it has to do with connected load. Basically the rule is this: If the equipment being powered is fixed in place, and it draws 50% or more of the circuit ampacity it has to be on its own circuit (and 'i wont run more than one thing at a time' doesnt fly)
Some examples:
-vertical air compressor on 30 amp circuit, draws 22 amps; needs its own circuit
-same air compressor on wheels; doesnt need its own circuit (but should have it anyways)
-portable heater; doesnt need its own circuit
-heater hanging from ceiling; needs its own circuit
-built in microwave; own circuit
-microwave sitting on counter; doesnt need its own circuit

How many tools do you forsee in yourfurture? Now you have a welder, but how about a grinder, table saw, compressor, heater, on other items that could be on a 220v circuit? List out your possible tools and think about how you can accomidate future growth.

I have 4 30A plugs/Circuits for pretty much anything (2 on each long wll of the garage about 12'' apart from each other), 1 40A Circuit for my compressor, and 2 50A Plugs/Circuits for the welder (and eventually plasma cutter) in the middle of the long walls.

I think that is sufficient for me, but I was told it was excessive (as was my double 110V plugs every 4'). All in all though, I am happy with it.

I've only got three in my garage. I have a 20A,30A and 50A. I wanted to put another 50A on the other end of the garage so if i wanted to I could plug my welder in over there when I get one but I just figured I would run it on a long extension cord. I guess it all just depends on what you have or what you plan to have in the future. I did however, run a piece of conduit into my panel that goes into the attic so I can easily add other circuits in the future.

If you are not sure of future use--or want to defer the cost of copper wire for later--just put in some boxes with conduit back to the pannel (or to an accessible spot in your attic). You can then run what you need when you need it.

Great idea - you should do one of these for each car. Some people laugh about electric cars but the technology is getting better fast while the cost of gas will continue to go up.

I have 5 . 2 for my 250A mig welder, 2 for the plasma cutter and 1 for my air compressor. Lets me be able to move my machines around depending on where the work is.

Hmmm. This sounds like a pretty logical idea.

Genius!@

My new home builder is charging me and arm and a leg to run these lines. Since it will be a new home, thought it be much easier when the frame is up and open, but.......

Was quoted ...$340 for each 30amp outlet and $100 for each 110v outlet. I can't imagine asking for a 60amp.

I guess I'll have them run some HUGE conduits up the ceiling and go from there. :thumbup:

Remember, if you put more than three current-carrying (hot or neutral, but not ground) wires in a conduit, you have to derate the ampacity of the wires. For 4-6 conductors, the rating is 80 percent of normal, for 7-24 conductors, it is 70 percent. That means that a 10 gauge wire may not carry 30 amps under some circumstances. Usually, 12 ga. and 14 ga. wire is derated anyway, so up to 7 conductors should not reduce them below the normal code ratings.

My point is, run separate conduits for each major circuit you might need. PVC conduit is cheap, and is just fine if not subject to physical damage. Use bigger sizes than minimum, especially if there will be bends. It will make pulling the wire much easier. For examply, at least 1 1/4" for #6 wire, but 1 1/2" if many bends and much length.

For the people with multiple outlets on the same circuit:

What did you use to tee off the 6-gauge power feed to the individual outlets? Can't seem to find any wire nuts that accommodate more than 2 6-gauge wires.

The only place I have two receptacles on a 240v circuit is on the 30A (10Ga) convenience receptacles, and then only two per run/breaker.
