Electrical Terms Definitions

Definitions of Electrical Terms

• Accessible (Equipment): Refers to equipment that can be approached easily, not protected by locked doors or high elevations.

• Accessible (Wiring Methods): Wiring that can be exposed or removed without causing damage to the building structure; not permanently enclosed.

• Readily Accessible: Items that can be quickly reached for operations or inspections without needing tools or overcoming obstacles.

• Adjustable Speed Drive: Equipment used to alter the speed of electric motors.

• Adjustable Speed Drive System: Comprises an adjustable speed drive along with its associated motors and auxiliary equipment.

• Ampacity: The maximum continuous current a conductor can carry without exceeding its temperature limit.

• Appliance: Utilization equipment typically built to standard sizes for tasks such as washing and cooking.

• Approved: Equipment or installations that meet acceptance criteria by the authority having jurisdiction.

• Arc-Fault Circuit Interrupter (AFCI): Device designed to protect against arc faults by de-energizing circuits upon detection of an arc.

• Attachment Plug (Plug Cap): Device that connects conductors from a flexible cord to a receptacle when inserted.

• Authority Having Jurisdiction (AHJ): The body responsible for enforcing codes and standards and approving installations or procedures.

• Automatic: Functions performed without human intervention.

• Bathroom: Includes plumbing fixtures such as toilets and showers.

• Battery System: Comprises interconnected batteries, chargers, and additional electrical components.

• Bonded (Bonding): Ensures continuity and conductivity via connections.

• Bonding Conductor or Jumper: A reliable conductor that ensures necessary electrical conductivity between metal parts.

• Bonding Jumper, Equipment: Connects parts of the equipment grounding conductor.

• Bonding Jumper, Main: Links the grounded circuit conductor with the equipment grounding conductor at service.

• Bonding Jumper, System: Connects the grounded circuit conductor to supply-side bonding or the equipment grounding conductor.

• Branch Circuit: Conductors between the final overcurrent device and other circuit elements.

• Branch Circuit, Appliance: Supplies energy to outlets for appliances without permanently connected lighting.

• Branch Circuit, General-Purpose: Supplies power to multiple receptacles or outlets for lighting and appliances.

• Branch Circuit, Individual: Supplies energy to only one utilization device.

• Branch Circuit, Multiwire: Comprises two or more ungrounded conductors with connections to a grounded conductor, having equal voltage among them.
