Ok I just went and looked in the panel and it already has a couple dual breakers in there. ( Duh, should have looked in there to begin with

)
So now I assume the panel accepts them since they are in there, is there a specific type or brand I should look for? Maybe just match what is already there?

I am comfortable with replacing/adding 110v breakers, that I have done. Adding a 220v will be new for me. Any advise or safety tips besides turning off the main power first? What size wire should I run for a 30 amp 220v circuit?

Thanks again for all the help!

It's always safest to match the brands when buying breakers. The wire you need is a 10-2 Romex w/grnd. This wire will work for a unit that does not require a neutral. If you need a neutral, you must run a 10-3. Be sure to color the white wire with a black or red or brown Sharpie or permanent marker in the panel full length and in the heater as this correctly identifies the wire as a current-carrying conducter.

Good luck, and if you are not an electrician, always turn off main breaker before working in panels or with power at all....and you probably should have somebody around to watch ya.

Thanks for the advise. Are those peanut breakers like half the size of a normal breaker? If so, sounds like a couple of those would do the trick.

I always get the wrong breaker when i go to buy one.. i would take a break with you to match it up. just make sure the brand is the same and has the same prongs on the back..

The first time I install a 220 breaker it was on a sub panel box and 220 would only work in certain spots which i didn't know.. i went crazy for like 2 days trying to figure it out. but i don't think main panel should have that problem..

the peanut breakers are the same size as a normal breaker there is just 2 breakers in 1 circuit breaker.

Glad I am not the only one that buys the wrong breaker the first time!

Taking the old breaker along sounds like a good idea. Thanks for the help!

just a little caution here make sure the spaces are on the same side of the panel in order to get 240volts
