220v compressor with a 240v outlet

[larryv]

If i have a 220v or 230v air compressor and a outlet rated for 240v can the compressor still be used if i change the plug? Thanks again.

It's 240v. I don't know why but people incorrectly call it 220v or 230v. Maybe an electrician can chime in on that.

Take a multimeter and check it. Every place I have done this at it was right around 240v +- 3 or 4 volts, even the old house I lived at in Idaho which was built in the early 1900s and used some knob and tube wiring still.

"U.S - Standardized at 120v. Electricity suppliers aim to keep most customers supplied between 114v and 126v most of the time. 240v/60 Hz used for heavy duty applications such as air conditioners, clothes dryers, stoves, ovens, and water heaters. Buildings with more than two branch circuits will have both 120v and 240v available. Type B outlets are now required by code in new construction and renovation. A T-slot Type B is rated for 20 amperes for use in kitchens or other areas using large 120v appliances."

Generally speaking, electric motors are designed for +- 10% of nominal supply voltage. A 220V motor will do fine on a 240V line.

This info comes from Reliance Electric's application data.

For all intents and purposes 220V is the same as 240V just as 110V is the same as 120V. It's all within the acceptable range.

Thank Guys for the info. Big help!

My understanding is that at one time everything whase 110V when the power grid got to large they bumped the voltage up to 120V. If I remember right they can bump it up to 150V if needed with no ill effects on the present system.
