I am making an extension cord for a 20 amp 220 circuit. I have some 12 AWG cord with two hots and a ground.
I will be using a metal box for the outlet end where the jointer will plug in. So with this arrangement should I tie the ground to the metal box, or will the box be grounded by default since the outlet is screwed to the cover?
