Hi All,
I've finally gotten around to wiring up the South Bend 13" lathe that I bought this summer, and I would really appreciate some advice on wiring the drum switch.
I put a Baldor 220V, Single phase motor in the lathe (model #L1322T) which is a drop in replacement having very similar specs to the original 3 phase motor. The wiring diagram on the motor is shown here. Note that there are 7 different wires coming out of the motor.
I have a 3 pole Allen-Bradley drum switch (model #350-TAV32) whose internal switching is shown here.
The only way that I can think to wire it up is shown below. Motor leads #2 and #3 would be connected together right at the motor. The rest of the motor leadss (5 conductors in total) would run the 5 foot distance up to the switch. That seems kind of complicated, but I've never wired this sort of switch before. I AM NERVOUS ABOUT LEAVING THE #4 TERMINAL "HOT" EVEN IN THE "OFF" SWITCH POSITION. Any advice that you could give would be appreciated.
(I should probably say that I plan to connect the bare, uninsulated ground wire to the case of the motor and switch, just in case someone else reads this in the future. This is a wire which doesn't normally carry current, but it there to provide a good path to ground incase something breaks.)
