Though the guy I lease my shop space from is good at wiring he is not sure about doing my cnc router. The 120 is ok but the 3 phase to the spindle can be tricky. It calls for a fused shutoff box too. If someone here in Portland or close wants to trade plane (s) to get me hooked up it would be great. There might be some noise issues from the spindle I need help with (though I hope not)

Buy the materials and me a plane ticket and I will come and do it for you:D Seriously, I would do it without hesitation if I was closer. I've hooked up a few CNC routers, make sure to get a real electrician involved especially if your spindle is controlled by a VFD.

Call most large electrical supplier and they can handle your needs of a fused disconnect. I think that's what your looking for. I just bought one for my newest thread here. About $212.00 with the 60amp fuses.
