Expert's Assistant chat
Customer: what would cause breaker on 17000 kw generac home standby generator to be thrown when utility power goes out. generator
came on but no house power. had to manually shut generator down. electrical co. who wired in generator and transfer switch
called it a fluke. an employee came and reset breaker, but never bother to look in transfer switch box nor house panel box.
they said it would probably never happen again. I tested generator few days later; it started and house power came on.
Does this make sense to you? the night utility power was lost, the local substation went down and 3 counties lost power.

Thank you for choosing Just Answer, my name is XXXXX XXXXX I will do my best to help you find the answer you need to resolve your problem.
There is no way to know exactly what happened but if it checked out and is now running correctly then I would not worry about it. When we loose power sometimes it happens in spurts. If you lost power and the generator kicked in then you got a power surge with the power kicking back in and then going out in rapid succession this may explain why the circuit breaker tripped. This is an odd occurrence and hopefully it will not happen again

John, once the utility power went out, the generator started but did not furnish any
power to the house. The generator never shut itself off as it normally would do if
it had provided power to the house and then shut off when utility power came back on.
The electrician never bothered to check the inside of the transfer switch to see if
everything was okay. The sales dealer in Des Moines for Generac had a person who
told me this was not normal and even though the generator runs, it could still be
hooked up wrong. What do you think?
I would have the dealer come out and check it out. It sounds like the transfer switch is hooked up right if the generator came on when the power went out and shut off when the power came back on. It not producing power does sound like something is not hooked up right. In my opinion I would have a generac professional come out and check this out. There is no need to chance it and have something else go wrong
Since I am not providing you a fix to this I do not expect you to accept the answers that I have given. I only hope that a Generac trained expert can make sure you are wired correctly for the next time you lose power
