Hi, this is my first post, happy to be on this forum.

The main breaker for our 3-phase/460v building power tripped on Friday and the Emergency Generator and ATS switched on. I noticed that the Genset out put display showed this: 468 v ,60hz , 715 amps total.

but each seperate phase measured around 235amps. is this enough to trip the breaker due to overloading?

I thought that a breaker marked 700 amps could hold 700 amps per pole?

thanks to all.
