I've got two 220V appliances I'm trying to add a receptacle for. I've got a dual-pole 25A breaker, and am completely replacing the existing outlet.
My issue is that one appliance has a standard NEMA 6-15 plug, and the other just has a four-wire pigtail. I'm trying to figure out how to wire them both up.
For the four-wire appliance, it looks like the NEMA 14-20 is the correct plug to attach to it. It should only draw 6 amps-- is there a lower-rated four-conductor plug I should use?
As for the receptacle, my understanding is the 6-15 doesn't use the neutral wire. Can I run 4 wires to a junction box and then have two outlets-- a 6-15 and a 14-20-- with the neutral only going to the 14-20?
Am I doing something terribly wrong or dangerous? This doesn't seem too complicated, but I've heard enough horror stories to be cautious.
The appliances are a table saw (13 amp draw) and a dust collector (6 amp draw). There's not room in the breaker box for another set of breakers, so I was hoping to get both on the same circuit. But it sounds like it's a better option to separate them?
The wiring diagram for the dust collector doesn't help me much-- it can be wired for 230V or 460V operation and details how to change that, but never specifies what the four leads are for. They're standard colors (black, red, white, green).
The existing breaker is two 25A breakers with their handles attached. Each connects between neutral and a different hot side in the box. I went with 25A over 20A just because the draw from both appliances is 19A and that didn't seem like a lot of room in case one draws a bit more on startup.
