Looking to purchase a Grizzly G0656W jointer, which is 240V, 12 Amps and requires a minimum circuit of 20 Amps. Jointer plug is a 6-20 plug. I already have a 240V circuit in my shop - it is a 30 Amp circuit I installed when I got my table saw. The only receptacle on this circuit is a L6-30, which fits my table saw.
What would be the best way to hook up this jointer to the 240V circuit:
1) Get a L6-30(male) to 6-20(female) adapter (if such an adapter exists in this male-female configuration)
2) Install a new 6-20 receptacle in series with the L6-30 receptacle.
BTW, the devices will never be running simultaneously.
Thanks.
