Study Notes
Circuit Breakers and Electrical Terms
- Qualifying Terms: Used in electrical terminology to denote specific characteristics like delay (inverse time), adjustment capabilities (nonadjustable), and predetermined values (setting).
- Concealed: Refers to equipment that is inaccessible due to structural components.
- Conductors: Differentiated as bare (uninsulated), covered (with non-standard material), and insulated (recognized insulating material).
- Conduit Body: A separate segment of conduit aiding in wiring systems.
- Pressure Connector: A device for connecting multiple conductors without solder.
- Continuous Load: Defined as a load expected to last for over three hours.
Electrical Devices and Equipment
- Controller: Governs the operation of other electrical devices.
- Cooking Unit: Refers to appliances specifically designed to be mounted on counters.
- Coordination: Aims to limit electrical outages by localizing overcurrent conditions.
- Cutout Box: An enclosure designed to mount on surfaces with doors that swing open.
Electrical Safety and Configuration
- Dead Front: Equipment design ensuring live parts are not exposed.
- Dusttight: Constructed to prevent dust intrusion, enhancing electrical safety.
- Duties: Classified as continuous, intermittent, periodic, short-time, or varying based on operational patterns.
Dwelling and Building Terms
- Dwelling Unit: A singular unit offering independent living facilities.
- Guest Room vs. Guest Suite: Defined by the number of rooms and amenities included for accommodation.
Grounding and Protection
- Grounding: Establishes an electrical connection with the earth to enhance safety.
- Ground-Fault Circuit Interrupter (GFCI): Protects personnel by cutting off electrical flow in fault conditions.
- Grounding Electrode: Connects an electrical system to the earth for safety.
Housing and Enclosure
- Hoistway: Refers to vertical openings like shafts or hatchways.
- Enclosure: Protective casing for electrical equipment, ensuring operational safety.
- Explosionproof Apparatus: Designed to contain and withstand internal explosions.
Wiring Systems and Conductors
- Service Conductors: Carry electricity from utility service points to building systems.
- Service Drop: The segment of overhead electrical service conductors.
- Sealable Equipment: Enclosed devices that can be sealed for security.
Miscellaneous Electrical Terms
- Electric Sign: Illuminated equipment for advertisement purposes.
- Remote-Control Circuit: Controls another circuit via relays.
- Voltage: Measures the electrical potential in a circuit, essential for system function.
- Utilization Equipment: Refers to devices consuming electrical energy for various applications.
Additional Considerations
- Special Permission: Required written consent from regulatory authority for specific actions or installations.
- Thermal Protections: Devices integral to motors preventing overheating and operational danger.
