Need help to night

My brother is pluged in to his generator 110/120? Outlet. Both mine and his cheap meters says he getting 130+ But he keeps blowing the breaker on the get set. Any ideas why hes getting 130 to start with and blowing breakers?

    This.

    The breaker trips because of too much current draw, that is, too many things plugged it and running.

    IF the breaker holds with nothing plugged in, the gen is probably OK.
    Outside chance the breaker itself is bad but probably not.
    I have a bad habit of forgetting to turn the A/C off when changing power sources.

    You probably are drawing too much current because of too many things turned ON or because one of the devices is defective........or a fault has developed in the wiring.

  • sounds like a portable generator ?
    what brand what model ?

    sounds like the voltage regulation is acting up/not set correctly
    130v is a little high but not outside of limits
    tripping the breaker is possibly something, surging (load spiking) on the higher voltage

    try turning off the converter charging the batteries and make sure the fridge is on propane (manually set to lp)

    some times the electric heating element becomes leaky, and will cause a GFI breaker to trip

    or turn off ALL circuit breakers in the 120v electric panel
    start generator
    plug in
    turn on only ONE circuit breaker at a time

    i hate typos..and i get them a lot..gaaah
