Which of the following is NOT part of the definition of premises wiring?

Premises wiring refers to the electrical wiring that serves a building or structure, which typically includes various types of circuits that are necessary for the operation of electrical systems within that space. This encompasses lighting circuits, control circuits (which are used to manage the operation of electrical devices), and signal circuits (which are employed for communication purposes within the building).

Mobile equipment, however, does not fall under the definition of premises wiring. This type of equipment is generally portable and used in applications that are not fixed to a single location, such as construction tools, vehicles, and other machinery that can be moved from site to site. Since mobile equipment is not stationary within the definition of premises and does not involve the wiring as part of a building's electrical infrastructure, it is accurately identified as not being part of premises wiring.
