I have my coote grinder and just picked up my 1hp farm duty motor, which can be wired either 110 or 220...If I set it up 110v I will use a dedicated circuit for the grinder only, with no other appliances. I could wire for 220 but this will cost me cash I dont really have right now, seeing that the breaker box is 150ft. away from my workstation and I am fresh out of the roll of wire...
MY QUESTION...will there be a noticeable difference with performance if I just use the 110 dedicated circuit? If it will, then I will bite the bullet and run the 220 wiring. Thanks for any help.
 
Just go 110v and save the $. Probally gonna draw around 13amps so it would be best to just have the grinder running on whichever circuit you use at that time.
 
yes, it said around 13 amps for 110. If I go with the 110 wiring, should I use a 15amp or 20amp breaker? Again, this will use its own dedicated circuit since I had alot of 12/2 wiring left over from re-wiring the house.
*the farm duty motor has a overload reset button if that matters.
 
you can wire the dedicated 110 ckt for 220
just get a 2/15 CB and 220 receptacle (or hardwire) and use the existing 2/12 (2 conductors, L1/L2 and gnd, no neutral required, a motor is a balanced load), current will be halved
 
110 is the voltage. He means that rather than use the white conductor as a neutral it can be used as another hot wire. 2 x 110 = 220v. All you need is a 2 pole breaker and a new receptacle and you're good to go for 220v.

yep, just tape it to ID it properly
 
Im going to wire a switch, is that going to create another set of problems for me? I was wondering that since both will be hot...I see what you mean, use the ground as a ground, and the white as another hot wire, and label it as such...right? How about that switch though?
 
240v single phase will use about half the amps as 120v single phase. it would be better to run it "220"
 
Use a double pole switch. That will cut the power to each line. Otherwise you will only switch one line the other will still be hot and probaly not good for the motor. The motors I have used at work, that are 110/220, always seem to run better with more torque when wired 220 volt.
 
I will go 220... What about wiring the switch with using the 12/2 wiring (hot black, hot white, copper bare ground)...
 
wiring the switch is pretty straight forward. There are 5 screws. 2 goldish ones on one side, 2 siler on the other side and a green (ground) usually at the top or bottom. Connect the blk wires to the gold screws, the white wires to the silver screws and of course the bare (ground) wire to the green screw.
