The green taped wire is the ground going to the house subpanel. This box serves as the main breaker box. Inside the main are the main dual 50 amp breaker, a dual 20 amp breaker for a well, and a breaker for an outdoor outlet. On main breaker boxes, I believe the ground and neutral are bonded, but will have to confirm.
Attached is a link on how the bare ground wire (tinted green) goes into the meter. The only ground connection between the meter and the main breaker box is the galvanized pipe. There is continuity between the boxes. Is this OK?
The big issue right now is grounding and ground/neutral buss bar. I want to make sure there is no more open neutrals. Replacing the bad breaker seemed to fix everything but want to safeguard all other possible problems.
Thanks for the help!
PS: This main breaker box will be replaced in the Spring.
