My garage had a single 15a circuit, which it shared with the mud room next
to it. That didn't leave much capacity for using any tools so I added a 20a
I got into turning and had to put the lathe in the garage as I didn't have
room in my shop. I ran the 20a circuit over to it.
I just upgraded my shop to a cyclone, so I have a 2hp DC left over; oddly I
can't sell it for even a third of it's retail value, so I am going to keep
it use it with the lathe.
Obviously I don't have enough power in the garage and have to run a new
circuit, but what...
1) I originally figured it would be a 240v as the DC is 240v only, but
didn't see that a 240v circuit in the garage would be real useful in the
future, for me or the next owner.
2) Playing with the motor wiring, I thought it could be converted to 120v.
Tech support confirms that it can, but they call it 240v only because of
concern over voltage drop at 16a. I could install a new 120v circuit, about
50' long and 16a; there would be some voltage drop, but not too bad.
3) I have a roll of 12/3; I could put in a one outlet multiwire circuit for
the lathe and DC. Since they would always be running together, the voltage
drop would be driven down some. But I have been a little paranoid about
multiwire circuits after I found one in my bedroom was installed
incorrectly, and 12/3 is harder to work with than 12/2.
All three options are reasonable, none are perfect; which would you do?
