Premises Wiring (System). That interior and exterior wiring, including power, lighting, control, and signal circuit wiring together with all their associated hardware, fittings, and wiring devices, both permanently and temporarily installed, that extends from the service point or source of power, such as a battery, a solar photovoltaic system, or a generator, transformer, or converter windings, to the outlet(s). Such wiring does not include wiring internal to appliances, luminaires (fixtures), motors, controllers, motor control centers, and similar equipment.

You've quoted the definition right out of the NEC, and I think this definition is way too broad. Doesn't this basically give the NEC jurisdiction over just about everything?

To me, premises means installed in, or attached to, a structure capable of holding at least one person. With the NEC definition, things that plug into the wall (wall warts) and things that interconnect appliances (hi-fi cables laying on the floor) are all covered. None of this stuff is installed when inspectors arrive, so why should it be in the code. Seems like it should be more of a UL listing thing and not a UL thing for my examples.

That's an interesting thought.

But the definition of Premises Wiring is not as broad as 90.2(A).

02 NEC
Quote
90.2 Scope.

(A) Covered. This Code covers the installation of electric conductors, electric equipment, signaling and communications conductors and equipment, and fiber optic cables and raceways for the following:

(1)Public and private premises, including buildings, structures, mobile homes, recreational vehicles, and floating buildings

(2)Yards, lots, parking lots, carnivals, and industrial substations

(3)Installations of conductors and equipment that connect to the supply of electricity

(4)Installations used by the electric utility, such as office buildings, warehouses, garages, machine shops, and recreational buildings, that are not an integral part of a generating plant, substation, or control center
