In the main circuit breaker panel, is the neutral bus bar always shorted to the ground bus bar? In my box which is about 30yrs old, both appear to be connected together.

That is correct if the panel also has the Service Disconnecting Means in it.

By service disconnecting means, are you referring to the main 100A breaker for the wire coming in off thestreet?

Is this 100 amp breaker the first disconecting means between your house and the utility, or is there another disconnecting means ahead of it, at the meter for instance?

I have a meter box mounted on the outside of the house that feeds directly into the 100A main breaker in the cb box I'm asking about with both the neutral and ground bars connected. I didn't look inside the meter box because it has a tag on it from the power co. so I don't know whats inside of it.
