I recently inherited my dad's Delta/Rockwell Unisaw with a 220V motor. The saw is a dream to use compared to my old Craftsman.
Luckily my shop is wired for 220 but I have a wiring question...
The wall plug is a 4 blade and the saw has a 3 blade plug so I need a new plug for the saw. I was going to just buy a new 4 blade male plug and replace the existing 3 blade on the saw.
So do I wire the ground/common from the saw to the ground or to the common on the plug? I can't seem to figure out which is appropriate.
Or should I just buy a length of 12/3 and use all 4 lugs? Does it matter? I assume if I did that all I would need to do is screw the ground to the saw frame somewhere... right?
