What kind of wiring does premises wiring NOT include?

Premises wiring refers to the electrical wiring that is installed within a building to provide electrical power and lighting. It typically includes various electrical circuits that connect the service point to outlets, switches, and fixtures, allowing for safe and efficient use of electricity throughout a premises.

Wiring internal to fixtures and devices is not considered part of premises wiring because this wiring is typically integral to individual devices or fixtures rather than part of the overall infrastructure of the building’s electrical system. Fixtures, such as lighting fixtures, fans, or appliances, already have wiring that is designed to be used solely within them, serving specific functions based on the manufacturer's design.

In contrast, wiring for portable appliances, power circuits connected to the service point, and control circuits for lighting are all aspects of premises wiring as they serve to distribute electricity throughout the building and connect it to the service point. This distinction helps clarify what constitutes premises wiring versus the internal wiring of individual electrical components.
