I have a dilemma. I have 100 amp service to my service panel. I have no open breakers so I would like to install a sub panel in my garage. I want to install a 240 volt garage heater as well as a 240 volt outlet for a welder that is yet to be purchased.

I do not know enough to do this myself (I know my limits), but I would like to understand what needs to be done so when I talk to someone I don't get taken or sound like a fool.

Things that might come in to play:
I live in a rural area and my meter is on a pole about 30 feet from the house.
My service panel is located on the basement foundation wall that the garage is located on above (is that clear?) so any runs from the panel to the garage should be able to be short.
The garage already has a few outlets so I wouldn't really need to change those or add any more 120 volt outlets.

What do I need to do?

Thanks
Jared

Call 3 or 4 Electrical contractors and tell them this and get quotes. It would help if you new the amperage of the welder before they pull wire. I would say most likely you would need an upgrade to a 200 amp service before adding the sub panel.

You'll need to open up two breakers in the main panel to feed the sub.
