Air compressor volatage question

[anthony22134]

I am installing a 230 volt air compressor motor and I have 247 volts at my outlet. Will this work and be ok for the air compressor or will I need a transformer. Alternatively I could get a different motor but I do not know if this would be ok.

247 is only around 7% higher then 230.

To me it's just like wiring a 460v name plate motor to 480v. I've heard 230v and 460v name plate motors are nema standard ratings to account for voltage drop.

I've also heard that 230 v and 460v was the nominal voltage supplied by utilities and they have since increased it to 240v and 480v.


I'm sure another member will chime in with a more articulate answer. But yes, you are good to go.

Thanks! I really appreciate it.

On the other hand, if a motor has a nameplate voltage of 200, it is probably just fine on (or designed for) 208, but may not be happy with 240.
For a situation like that, best to check manufacturer's specifications if you can find them.
