My Enco mill came to me wired for 115v. I have 204v available so I'd like to rewire it to take advantage of that. Problem is, it doesn't appear that the wiring listed inside the motor box cover is wired exactly like it shows in the diagram. Can someone help me with how to properly make this change?

Tahnks,

Terry

Post whatever diagrams you can find from the machine/motor so I can take a look

Thank you Mark. I'm sorry to be electrically challenged. Zero information in the manual. I downloaded the Jet manual since they still use this same switch setup but all it says is follow the instructions on the inside of the motor box cover.

Switch...



Motor:

Top left 1 - 3- to circuit breaker
Center left
5 - red
Bottom left
2 -4 - black

Top right white - to circuit breaker
Center right blank
Bottom right 6 - yellow



Inside of motor box cover:



Wiring diagrams that the original owner drew in the manual:

Thank goodness the motor wires are still numbered, that helps a lot. Ok so currently motor wires 1 and 3 are connected together and 2 and 4 are connected together correct?
If so then just reconfigure the motor terminal block wires like the following:

If the motor rotation is backwards from the switch handle then swap the white and black wires going from the switch to the motor block, either at the motor end or the switch end. Alternately, you can swap 5 and 6 instead. - Enjoy!
ps the yellow can be disconnected at one end or both ends- doesn't matter

pss 220 volt line wire colors are supposed to be black and red according to code, but you can do what you want, it's your machine. If you do sell the machine though, be sure to tell them that it's wired for 220

Correct, 1 and 3 are together and 2 and 4 are together.
