Applied Codeology - Ch 2 - Building Blocks, Definitions

The conductors and equipment for delivering electric energy from the serving utility to the wiring system of the premises served.

• Service Drop

• Service Cable

• Service

• Service Conductors

The necessary equipment, usually consisting of a circuit breaker(s) or switch(es) and fuse(s) and their accessories, connected to the load end of service conductors to a building or other structure, or an otherwise designated area, and intended to constitute the main control and cutoff of the supply.

• Service Drop

• Service Lateral

• Service Equipment

• Separately Derived System

All circuit conductors between the service equipment, the source of a separately derived system, or other power supply source and the final branch-circuit over-current protection device.

• Grounded Conductor

• Feeder

• Service Lateral

• Service Point

A device capable of providing protection for service, feeder, and branch circuits and equipment over the full range of over-currents between its rated current and its interrupting rating. Such devices are provided with interrupting ratings appropriate for the intended use but no less than 5000 amperes.

• Switchboard

• Panelboard

• Over-current Protection Device (OCPD)

• General Purpose Switch

Capable of being reached quickly for operation, renewal, or inspections without requiring those to whom ready access is requisite to actions such as to use tools, to climb over or remove obstacles, or to resort to portable ladders, and so forth.

• Accessible (as applied to equipment)

• Accessible (as applied to wiring methods)

• Readily Accessible

• In Sight From

The circuit conductors between the final over-current protection device protecting the circuit and the outlet(s).

• Service Entrance Conductors

• Feeders

• Branch Circuit

• Control Circuit

A system or circuit conductor that is intentionally grounded.

• Grounding Electrode

• Grounded Conductor

• Equipment Grounding Conductor

• Grounding Electrode Conductor

A device designed to open and close a circuit by non-automatic means and to open the circuit automatically on a predetermined over-current without damage to itself when properly applied within it's rating.

• Fuse

• Circuit Breaker

• Switch

• Outlet

Connected to establish electrical continuity and conductivity. (select all that apply)

• Grounding

• Bonding

• Grounded

• Bonded

Connected (connecting) to ground or to a conductive body that extends the ground connection. (select all that apply)
