If there is power entering into the breaker and none coming out, the breaker is tripped or bad, end of story. If there is not power coming into the breaker on both legs, most likely issues are either a bad leg on the shore power (but you checked that) a bad wire in your cord (but you checked the power entering the transfer switch) or a bad relay in the transfer switch (my vote). I have "fixed" several customers problems by loaning them a rubber hammer and showing them where to tap (on the transfer switch itself). A transfer switch is nothing more than an electromagnetic switch that swings a lug when power is present. The lug can get stuck, for lack of a technical term. The generator's output does not go thru the transfer switch, so you would have full power on generator, while only half if the problem is the transfer switch or any of the other issues upstream to and including the pedestal.lanerd wrote:
I would first check the transfer switch output lugs to make sure you have 120 on both L1 and L2.
I have checked the voltage on both L1 and L2 wires coming into the 50 amp breakers and they are both 120v.

You say you checked both L1 and L2 on the main 50 amp breaker and have 120 vac incoming on both. But did you check the load side of the main 50 amp breaker to make sure you have 120 vac coming out of the breaker to the distribution panel. Main breaker could have a bad leg.

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.
