First means of disconnect

[joeyww12000]

when bonding a service you must bond in between the source and the first means of disconnect....correct? If I have a disconnect outside the building and a MDP with a main breaker inside then I would have to bond at the disconnect correct? Could I bypass the disconnect outside and bond at the MDP?

You need to bond at the service equipment -- the disconnect. Then you must ground the MDP.

this is not whats on the specs, or the riser diagram, at my current job.....it shows no bonding at the disconnect... the MDP has all the grounding electrodes such as steel, waterpipe, ground rod being bonded to service in the MDP....what gives you think?

The only possibility I can think of would be your outside switch being a POCO required "cold sequence switch" {per 230.83(3)}ahead of metering in which case it would not be service equipment
