Upgrading power to 220

Curious if anyone has had experience getting 220 installed in a detached garage or something like that. I have called for a few quotes and the price is much steeper the I imagined.

If you don’t mind my asking what did it cost if anyone had a similar project?

Any creative alternatives?

Do you have any dedicated circuits out there… besides your garage door?

My main panel is on the back side of the garage so i just poked thru and ran it in emt

I am working in a garage with only 110V power, and went a bit extreme and built a 220V power supply with server rack batteries for storage. I have a feeling it was steeper ($5k or more) than getting 220V run in, but I don’t own my place, plus I now have my own “powerwall” home backup if needed. The hard to find solution was to be able to charge the batteries from 110V while inverting to 220V, and I did it with a pair of linked victrons to get the 2 phases. It looks like ecoflow now makes an all in one system that should do the same for less money than I sunk into my odd little server rack cart.

I can’t imagine actually paying someone to do something that simple. Go to Home Depot get some wire and run in either in the air or underground and hook it up. I mean really it’s only 3 or 4 wires. L1,L2,Neutral & Ground.

@lcworx Mostly i guess i was worried about doing it “correct” but yeah i think that is my new plan. The quotes are rediculous.

@Chris I am out of breakers but my research has found a solution that doesnt require replacing the panel.

@jtcreasy iteresting solution, definitly more then i want tonspend though.

Can’t stress enough that you should test the GFI/breaker even after you think you have the circuit turned off, before you start wiring the additional circuit.

Definitely! I always probe everything before I stick my hands on it. I have some experience in the automation field messing in panels, just don’t know residential codes and what not. But always a good reminder!

I’m just lucky enough to have a son who is a commercial electrician. One thing to consider is your house insurance and what happens if there is a disaster. Do you need to get a wiring permit and have the wiring inspected. Here in Canada you must have the correct color for the different wires. If not you use colored electrical tape on both ends signifying what the wire is for.

For comparison, I live in NE Florida and just moved into a home with a 2 car detached garage. It had a few power outlets and two lights. I added two lights, added 2 independent 220V plugs, and about 10 more receptacles. My ‘shop’ already had its own 100A panel. Conduit up the walls, open wire in the ceiling. Total cost was $2k.
