I have installed a window air condition unit through the wall of my garage which is fed by 240 volt, 10 gauge wire to a single outlet.

My question is, in as much as it is a single outlet and only one appliance at a time can be active, is there any reason I could not use a pigtail from the heater to the same outlet, alternating which one is plugged in on a seasonal basis? I would like to avoid having to run another wire and getting in to the box if at all possible....

I'm assuming the pigtail would need to be 10 gauge to meet mfg. specs.

The heater will be suspended from the ceiling as provided by the mfg. brackets and will be within 3-4 feet of the outlet.

Would a pigtail of this nature be available in local hardware stores (Nashville) or would I need to go to an electrical supply store?


You can use the same recept for either device as long as the recept is rated for 240v and 30a. Then you will need a cord cap with the proper configuration to match the recept. Some 'sjo' cord from an electrical supply house, or maybe from a Home Depot type joint, will work. Just make sure everything is grounded according to code, use #10 or #8 wire and terminate it on a 30a 2 pole breaker.
