Are 208 and 230 interchangeable? I have a motor that has to be connected, and the nameplate says 230/460V, but it came from the factory with a sticker on it that says 'wired for 208V'. I'm a little confused because I'm not sure how to supply this with 230V without putting in a transformer. The service in the building is 277/480V, and it's stepped down to 120/208V for receptacles and such. Any help is appreciated.

Most ones I have seen have an fla listed for 208 and 230. There isn't any wiring difference on a normal motor. I would guess that if this is a packaged piece of equipment with a starter in it that they set the overloads for 208.

Look at the nameplate and see if it gives three amperage ratings. Sometimes it says the 208 amperage in a different area on the nameplate.
