I'm installing an air conditioner that requires 220 in a new office in my barn.

I've run wire rated for 220. Can you tell me what I need to know to buy the breaker. I'll figure the wall plug out from the a/c unit itself.

Is there any special wire configuration @ either end (female wall recepticle or breaker box).

Also, can I put junction box in and run a second appliance on a seperate plug (I have an electric dryer I want to put in the barn for backup.

Thanks in advance for your help.

I have a lot of questions:[list=1][*]What gauge of wire did you run?[*]How many insulated conductors are in the cable you ran?[*]What type of cable is it (e.g., NM-B, UF, ??)?[*]From where to where did you run it?[*]Do you currently have a subpanel in the garage?[*]What size breaker do the specifications for your A/C ask for?[*]What is the brand of your electrical panel.[/list=1]
