Quincy Compressor Wiring

[K72nova]

I bought a Quincy 5hp 60 gallon compressor model # 2V41C60VC, I had 220 run in my garage but now I'm running into a bit of a snag hooking into the compressor. I have never worked with 220 before so I am a bit confused on this. here are the pictures and diagrams that Quincy provided me with on how to hookup the compressor.



Well I went to the hardware store and picked up a Dryer cable of the appropriate amperage thinking that it would be the correct thing for it and to be safe I bought the 3 and the 4 cord cables. I noticed that on the diagram it shows to hook a Green (Ground), Black (Hot), and a White wire wrapped in red tape? I have no idea if that is supposed to be a Hot red or a Common white. Has anyone hooked one of these up before? I am doing something completely wrong or looking too much into this? I can usually figure something like this out I'm just a bit stumped today, maybe it's because of the first snow of the year today?.

On 240 you have 2 hots and a ground. Your screw terminal and white-red wrapped wire are hot and should be interchangeable. Wire it up and see. Worst that can happen is a tripped breaker. Green wire should attach to frame of pressure switch.

You need 2 hots and a ground for deliver of 240v. Neither of the hots is different from the other except for the color of the wires so in reality they could have the same wire color.

As a sidenote, if you have questions, Larry at Quincy will be very helpful with the wiring. Who is the manufacturer of the switch on your unit?

Looks like you have terminals that have jumper wires so that it could be used for 3 phase also. Hots would have to go to 2 of the terminals that are not jumpered. I'm not sure why there is a wire that needs to be spliced into. I would think that could be removed and a hot would go directly to where the red shorty was. Why have another splice on the system?

With regards to the wires that you bought, you'll likely use the 3 wire. If your 240 outlet is wired normally, then it will have 2 hots and a ground. If there was a 4th neutral wire then you could wire a 120v hour meter for instance, but this could also be done with a 240v hour meter using the 2 hot legs.

Check your outlet do that you have a good understanding of how things look and to confirm that things look kosher.
