I've had a real eye-opening discovery. While the installs I see that have this detail are nearly as old as I am, the local town tells me that, in their opinion, the NEC still allows the practice, so they have a local ammendment.
The 'discovery' is that it's quite possible to hane NO main disconnect on a home ... not outside at the service drop, and not at the panel inside ... so long as you have six MWBC's or less. Hey, I can do a house with twelve circuits ... especially if all the appliances are gas!
Imagine that ... all the way from the PoCo transformer to the panel set well inside the house, with no means of disconnection. Let a rocker run a wire into that Romex feed to the panel, and the sparks won't stop until the PoCo comes out. Or the screw is vaporized. Or both. Add a 'tamper resistant' meter ring and you've just added to the danger.
I have issues with that. Current NEC says the 'disconnect' has to have a minimum 100 amp rating - but that's only IF you have a disconnect. Nor does the NEC require it outside, at the service.
What do you say?
