220 volt recptacles and plugs???

northslope

I need to run wiring for a planer. It is a 3hp, 220volt, 13.5 amp motor. I am running it off of 10 gauge wire going to a 30 amp breaker. I also 10 amp wire for the cord. When I got to the store to pick out a receptacle and plug there were so many choices I didn't know which one to get. I'd like to have this recptacle available for any other 220 volt tools I may get in the future (I understand I can only use one at a time). Also for a switch at the planer is a 20amp two pole OK? Thanks

You are running a 30 amp circuit, so I would use a 30 amp recepticle and plug. You don't need the 30 apm right now but may later. I would install a 25 amp inline for the planner. You should be able to use a 20 amp double for the switch.

For 240 Volt, 30 Amp circuits, if you want to use straight blade devices, you want a NEMA 6-30:



Twist-lock devices would use a L6-30:

OK, thanks for the info. Of the plugs and receptacles you mentioned is one more common in use than the other? Why so many choices even at 30 amps, it seems like they made every possible configuration. Round ground with two horizontal spades; L-shaped ground with vertical spades; 3 spades, etc., etc....

This is like saying why do they make so many different shapes and sizes of knives.
They all have different purposes and uses.

The NEMA 6-30 is probably the most common. I installed these in my workshop. Heaters, table saw, and others have used this. Only thing differing so far was welder and plasma cutter - which I made a converter from the NEMA 6-30 to the welder/cutter.
