I'm poking around in my breaker box and I notice a white wire screwed into the ground bus. Tracing it back, both bare and white are on the ground bus and the black is screwed into a breaker. Is this up to code?
This circuit is connected to an RV plug.
Secondly, I also notice a bare wire screwed into the neutral bus. As far as I can tell this is 14-3 Romex with bare & white to the neutral bus and black & red to different breakers. Is this up to code?
Both of these circuits are additions by the previous owner.
