Location: US Residential.
I have a line already which can support up to 25A 2 pole (in breaker panel) I have 2 devices, each rated 220/240V 2-pole. However, at any given time only 1 I need to run. For example: summer : Device SUMM, winter : Device WINT.
Thus I am looking for [??] which when installed into this power line can effectively switch between SUMM and WINT.
Notes: Both SUMM and WINT can be directly wired using a J-box. Notes: Both devices are residential rated and so sustained current or temp. ratings are fine. Notes: I have seen switches do this but flipping them from devices SUMM or WINT usually causes a transient surge / a small flash and that's something I'd like to avoid. In my naive mind, I feel such a surge/flash will not occur if the devices happen to have their own power switch and are switched off before transferring. Of course another option would be to flip the breaker off, transfer and switch the breaker on. I am fine with that approach. My breakers are QO.
