Is 208v acceptable in a 2hp 115/230v motor

It depends entirely on the load profile.

If the load is easy to start and does not load the motor to its full power, you could probably run it on 180 volts and be just fine.

If it's a centrifugal pump, you couldn't ask for an easier start. But all we know is "pump", it could be a positive displacement pump starting against head pressure for all we know
