I've been asked by a customer to upgrade the service on a house he just pruchased. The house is a bungalow that had the main floor and basement separated into individual residences with each having their own service including meters. The local utility company has approved a service layout for the upgrade from 2x 60A services to 2x 100A services. Each with their own meter, but fed from the same O/H supply.

However in researching this, I found Rule 6-102(c)(i). I'm too lazy to re-type the whole thing, but basically it states that you're not allowed to have separate services for residences located one above the other.

If this is true, then why has the local utility approved the upgrade? Or would this house be grandfathered? I checked my old 2002 Code Book and it reads the same as the current book.

Or am I reading this and interpreting this completely wrong?

Can anybody shed any light on this?

Thanks... Bruce
