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.
