Help me choose a contractor

[ALinCarolina]

My air compressor is in the basement of my shop which has worked out well for noise, etc. When I was building the shop I had the foresight to run 14 ga wire from a switch by the front door down to the compressor site, planning on installing a contactor/relay to be able to turn the compressor off and on without going down to the basement. I'm ready to do that now but want to be sure I get the right size and type of contactor and the choices are bewildering.

The compressor is a big one. Duplex with two 7.5 hp motors supplied with 4 ga from an 80 amp breaker. Can anyone give me a model # or link to an appropriate contactor for this beast with a 120V control side? Hoping this is a reasonable thing to do.

Sorry for the thread title error, I typed contactor, not contractor, but auto correct did its thing. I may have to start it over.

The relay only needs to handle the amperage of the motor starter coil, which is very minimal. Depending on your particular wiring scheme, a contactor may not even be needed. You may likely can control the motor starter coil(s) with just the light switch. It only has to be inserted into the 120 volt circuit controlling the coils. Does the compressor already have motor starter(s) installed? How far are you from Goldsboro?

Thanks RJ. I'm in Union county near Monroe. This is what the control box looks like.
