    208v motors @240v

    UPDATE, As I wrote the original post in an agitated state at 3am, I went back to the drawing board and found the motors were 208/220, so I called up the roaster mfg and they said they set the overload switches low at the factory, and had me adjust them,up about 5%, now all is well. Thank you all...

    208v motors @240v

    Thanks Scotty, The supply and motor are both US 60hz The supply being 240v single phase and the motors 208v single phase. So the ratio being 4.0 V/Hz instead of 3.46 V/Hz would be enough to trip the overload switches in the panel? The motors seem to be running really hot. Bob

    208v motors @240v

    I have a 4 motor coffee roaster that the motors are rated 208v and I have 240v. After running the machine for a while the breakers in the panel shut the motors off. What would you suggest for a quick fix? There are 3 1/2 hp and 1 3/4hp motor in this mix...I think there is a 30 amp circuit...
