5HP motor electrical hookup
I recently acquired a grizzly 5HP table saw. The current male plug that is installed on it (looks like its from manufacturer) is a 3-prong NEMA10-30. In doing some research, that is an older style of dryer plug that used a hot-hot-neutral configuration where, in practice, the neutral was grounded effectively making it hot-hot-ground. Somewhere around 95/96 the switch was made? Anyways...
I have a 2 year old new construction that they put in a 240V receptable in the garage of style NEMA14-30 operating as hot-hot-neutral-ground. I confirmed that is how it is wired.
My question - i'm not sure how I can make the 3-pronged plug work with the 4-pronged outlet. My intuition says if I made a custom adapter I could just wire the NEMA14-30's neutral & ground together and that would work. But I don't have much experience here and would appreciate guidance. I guess I could also run a new wire with the newer NEMA14-30 style, but since the old plug didn't have a true neutral, I don't know where to place it into the magnetic switch, nor does the manual help me.
