I am trying to wire a new receptacle to a pre-existing 220v line that
a dryer in my shop- the welder requires a 30 A line which this one is,
a NEMA 6-50 receptacle. I can see that the dryer receptacle has two
hots ( red and black) and a neutral white- however, i see that the
6-50 needs two hots and a ground.
I am assuming that this means the existing line can still be used with
a few modifications- it is 10/3- .....tape a green indicator on both
ends of the white and make that a ground? is this correct Thanks for
