You have a 120/240 receptacle. Your saw is 240 only. The best option

If I understand your comment...the receptacle is a 220v only. There
is no way to plug in a 120v line and it has a 40 amp breaker.

No he wrote and was right that the receptacle is both 120 and 240
supply. You saw only can use the 240 part of that. Some things like an
electric range will have 240 heating elements and maybe a 120 clock so they
need both.

You could replace the plug on the saw and you would not connect any wire
to one of the connectors on the plug (the one that feeds the white wire, you
would only connect the red black and copper-green or as he suggested and so
do I, leave the plug as it is on the saw and replace the receptacle on the
wall with one that will fit the existing plug designed for 220 only, you
would not connect the white wire to any part of that receptacle.


So you are saying wire the "common/grround" from the saw to the ground
on the receptacle... right?

The common and the ground are NOT the same thing. The only place the
connect is in the breaker box any where else the white is a current carrying
wire and should be treated as such, the ground is the only ground wire.


Sometimes they're connected together (often in 240V 3-wire cords).



Thanks!
