Utlization voltage tolerance

[mbrooke]

What is the maximum voltage 120 volt equipment can safely handle?

Depends on the equipment. In general, it should be able to tolerate +10%.

That comes out to 132 volts? Id think that's to high?

Looks like 127 volts is the cutoff then.

I had the +10% right, but NEMA uses 115V as nominal.

And do not expect the application of voltages at the high or low end of tolerance to work out particularly well with incandescent light bulbs!
Equipment is not just motors.
