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.
