Question:

I am going to wire a new house in a city I have not worked in before. The city electrical inspector told me the Meter Base Disconnect is optional even with the distance between the meter base and the load center being located 40 feet from each other. Does the NEC not require a disconnect be located outside connected to the meter base if the load center is located that far from the meter base?

A

Answer:

Hey David thanks for your question. The service disconnecting means can be located outside or if located inside it must be nearest the point of entrance of the service conductors as stated in 230.70(A)(1). No dimension is given for either location but if located inside it must be "near". Some areas have local requirements for service disconnecting means to be located outside.
