My first question is , my shaper is 3hp , my jointer is 3hp. I plan on running off the same plug not at the same time. Is there any issues with changing the 220 plug on end of shaper to one like on end of jointer? I would use the same amperage plug , 30 amps. I think the jointer is a Nema 6-20 Plug. The round 4 prong with a bit of twist when I insert into wall outlet.

Another 220 question if I turn a single 220 receptacle into a double 220.
Do I u just use jumper wires to get down to the lower receptacle if i'm hot wired to the top?


THANKS
