Half of 120 volt buss is dead

I have lost the power to half of the 120 volt power buss. I have checked the main 50 amp breaker and it is good. Both L1 and L2 incoming are hot. Half the breakers are hot, the other half of the breakers are not. I can usually figure these things out, but this one has me baffled. Appreciate any ideas.

    50A Service is two separate legs of 120V power, so you can loose one of them.
  • Yes I have a generator. Wouldn't the transfer switch affect the entire 120 volt buss, not just half of it?
  • You could try swapping the incoming wires between the 50 amp breakers. Could be a faulty breaker.
  • Do you have a generator? If so check the transfer switch.
