Study Notes

Definitions and Concepts

  • Ampacity: Maximum continuous current a conductor can carry without exceeding its temperature rating.
  • Appliance: Utilization equipment, typically non-industrial, designed in standard sizes for specific functions (e.g., washing, air conditioning).
  • Approved: Acceptable to the authority having jurisdiction (AHJ).
  • Askarel: Nonflammable synthetic chlorinated hydrocarbons used as electrical insulation.
  • Attachment Plug: Device that connects conductors of a flexible cord to a receptacle.
  • Authority Having Jurisdiction (AHJ): Entity responsible for approving equipment, materials, installations, and procedures.

Equipment and Devices

  • Automatic: Operates by its own mechanism when influenced by factors like current or temperature.
  • Branch Circuit: Conductors connecting the final overcurrent device and outlets.
  • Circuit Breaker: Device designed to interrupt a circuit on overcurrent while remaining undamaged.
  • Conductor Types:
    • Bare Conductor: No insulation covering.
    • Insulated Conductor: Encased in material recognized as electrical insulation.

Electrical Load and Control

  • Continuous Load: A load that maintains maximum current for 3 hours or more.
  • Controller: Device that regulates electric power delivered to connected apparatus.
  • Cutout Box: Surface-mounted enclosure with doors or cover for protection of electrical devices.

Electrical System Metrics

  • Demand Factor: Ratio of maximum demand of a system to its total connected load.
  • Device: Component intended to carry or control electric energy without utilizing it.

Safety and Protection

  • Disconnecting Means: Devices that can disconnect circuit conductors from their power source.
  • Electric Sign: Electrically illuminated equipment displaying words or symbols for information.
  • Enclosure: Protective housing for apparatus to prevent accidental contact with energized parts.

Grounding and Fault Protection

  • Energized: Refers to equipment or circuits connected to a voltage source.
  • Equipment: General term encompassing all parts of an electrical installation, including materials and devices.
  • Feeder: Conductors between service equipment and final branch circuit overcurrent device.
  • Ground: Conducting connection to earth or a conductive body serving as the earth.

Grounding Components

  • Grounded: Connection to earth or similar conductive body.
  • Ground Conductor: Intentionally grounded circuit conductor.
  • GFCI (Ground Fault Current Interruptor): Protective device that de-energizes circuit if ground current exceeds set values.
  • Grounding Conductor: Connects equipment or the ground circuit to grounding electrodes.
  • Grounding Electrode: Establishes electrical connection to the earth.
  • Grounding Electrode Conductor: Connects the grounding electrode to the equipment grounding conductor.
