Hello, I was looking on the web for an answer to my question and came across this site, I'm sure there will be someone here who can help me with my questions and problem. I've done a fair amount of wiring but this job has really got me stumped as to what I need to do.
I am in the process of wiring a Bridgeport milling machine with a J head, I believe it's a 1964 model. On the tag with the motor it says 1hp 2ph 60cy. 220/440, 3.26 & 1.63 amps. another tag says Induction Motor, type QZA, Frame 4570. The switch has a forward & reverse, there are 8 wires from the motor to the switch, 6 wires go to poles on the switch and 2 wires are hooked together with a green wire coming from them that appears to of been a ground but isn't hooked to anything at this time.
My problem is I don't understand the 2 phase, I've never heard this, only single and 3 phase. I would like your impute as to wiring this machine, do I use 220 single or 3 phase, or ? This is just for my own personal use, the days of long hard work for this machine are done while I have it.
Also I'd like your impute as to what I need for wire, it's 50' from the breaker panel to the machine, do I use 12/3 w/g, 10/3 w/g or ?
Also I have a 5hp converter for 3 phase for my lathe but if I don't have to use it for the mill, I'd just as soon not, I've read where 3 phase is better for reversing the motor but again I'm not familiar with that, I'd like someones impute on that also, I'll do what I need to do.
Thanks,
Wayne
