i have a 240v 30a circuit that isn't being used, but is wired for a dryer. I have an electrician coming to convert it so i can power an a741/apw3 and t9/apw3, 2 apw3 total.
what power cable do you guys use for this PSU?
what would be the simplest outlet/approach to instruct the electrician for conversion?
You would be best served by grabbing a cheap 30A PDU and just replacing the plug on the PDU for the matching dryer plug ignoring the neutral (so you don't have to change the existing receptacle at all). If you bring the PDU into a hardware store, they might even help you change the plug if you don't feel comfortable doing it yourself. That way you're not limited to just 1 APW3 PSU, you can expand down the road if you decide to, and when you unplug the PDU the receptacle is still available for use with a dryer.
