I was giving a 30 gal Ingersoll-Rand compressor.


It has 5hp 230v 15a 60hz phase 1 motor.

I don't have 230 v at my house to plug in and test it.

It looks to me that maybe someone rewired it to run 110 not sure though. Is there any way I can test this at home?

What Buster said.

Additionally, if you just want to know if the motor is functional, you can run it at 120, but you'll only get maybe 1 HP out of it.

Look at the power meter on your house. It's almost certainly type 240V. If so, then you can have an electrician run 230 (240) for you if you want to use the compressor.

230 volt motor

Hey Carl, by looking at the picture of the motor data plate, this is a 230 volt motor only! You can't convert it to 120 volt without going into the motor windings and rewiring the connections, not advised.

If you can use a multimeter, you can check the windings for continuity and for grounds as a quick check.

Can't tell anything about the second picture, looks like the pressure switch connections with no wiring connected?

This starts and stops the motor at the pressure it is set up for, not voltage sensitive.

Hope this helps, Have a great day!

Buster
