new circuit breaker for garage.
I need to add more power to my garage as I'm using it to power lots of power tools. The current breaker only holds about 10amps, I need to know how to get more juice flowing to my work space? The main panel is a 200amp box, I will provide more info if needed. A rough estimate of pricing for this job would be appreciated as well. Thank you.:confused:
Along with power tools, I would also like to add an AC unit in there because the heat could become a health hazard during the summer months. How big of a circuit breaker should I be looking at? |
Well, by code, the AC needs to be on a separate breaker.
The regular outlets need only to be run in, hooked up at the outlets then installed in the panel, ideally on their own breaker also. Since the AC unit is possibly a 220 device, you may want to do some home work before you dive in. Cheers, knewshound |

Central air? Wall unit? How big? From the feeling of your questions I think you would be best served having someone come in and give you a price to do this work. Better yet, draw up a list of needs and get a few prices for the same work so you are making an even comparison. |

I guess my question is what is the best way to get power I need into my garage? I would be happy to provide more info about the set up needed. Thank you for answering my question. |
the wire you are going to run will determine what breaker size you need. i would probably put in a 100 to 125 amp panel. you can install a larger panel than the wires load capacity, you just have to protect the wire's capacity by correctly sizing the breaker for the wire. i think supply houses usually sell 125 amp panels around $40.00 after sizing up your wire and breaker you have to find just what is available. in essence if you need 65 amps for a circuit you can buy a 70 amp breaker but will probably only find 100 amp wire, which is ok to be protected by a same size or smaller amp breaker. what you can buy locally will play into your plans too. if your garage is attached and the outside panel is in the general area, you will spend 150 to 250 bucks on materials. you may need 110' feet of 12-2 w/g wire and the best buy will be a 250' roll. and so on. be safe. hire a licensed electrician if confused.

Is the garage attached or detached. The methods are very different between the two.

The best bet for a detached garage is to set a sub panel inside the garage. 100A sould be more than enough for what you want to do, but give you some flexability if you want to expand. How far is the run between you house service and the garage? Also, what size wire is coming into your house and what size panel is in your house now?

Also, it will depend on current and future tool capacity. This sounds like it will be multiple circuits. That's why people are recommending a sub-panel. 100amp sub panel then circuits for AC, lighting, outlets, etc.
Some power tools may even want their own circuits. I have a table saw that is on its own 30a 220v line, same with a dust collector. My jointer and my bandsaw are also hooked to 220v lines. My planer is 110v but draws 15a, If I tried to run that with something else on the same 15a circuit at the same time I would trip the breaker. The planer is on a 20a line and gets run at the same time with a dust collector on its own 220 line, lights on their own circuit. If I have someone working with me in the garage there is a possibility of another big tool on at the same time as well. It was all planned out so I would have sufficient power where and when it was needed. |
