Electrical help onsite Salem Oregon
[Salem, Oregon] I've got an issue with my Home main breaker box. While all circuit breakers are "on" Some circuits are out or at a very low voltage. It started when I tripped a circuit on a tandem 20AMP breaker. When it tripped a third time while testing wiring, other circuits not related to that breaker no longer came on. And they are not just on one side of the breaker box, it's on both left and right side. I have turned all breakers on and off as well as the main power. The same circuits are not coming on. These circuits range from 20AMP to a Tandem 50AMP (Dryer). My knowledge is limited as to whether it's a breaker replacement, multiple breaker replacement and possibly even a bussbar issue. I'm guessing in the dark here.
