Electrical Components and Tools Quiz

Study Notes

Electrical Components and Terminology

A fuse protects circuits from overcurrent by breaking the circuit when excess current flows.
Circuit breakers can be reset after they trip under overcurrent conditions, allowing the circuit to function again without replacement.

Electrical Tools and Maintenance

Maintain tools by keeping screwdriver blades sharp and regularly PAT testing power tools.
Tools should be lightly oiled and stored safely in a dry, secure location.

Fasteners and Fixings

Wall plugs and wall bolts are used for securing fixtures to walls.
Dome head slotted woodscrews are designed for use in wooden applications.
Plasterboard fixings effectively anchor in drywall.
Countersunk woodscrews allow for flush mounting with the surface.

Types of Screws

6mm roofing screws or gutter bolts are suited for securing roofing materials.
Cable clips are essential for organizing and securing electrical wiring.

Socket Outlets

A two-gang switched 13A socket outlet allows the control of power to two devices.
A one-gang, unswitched 13A socket outlet provides constant power to one device.
A one-gang metal clad, surface mount switch is durable and ideal for exposed areas.
Two-gang flush mount socket outlet back boxes ensure a neat installation within walls.
Two-gang flush mount plasterboard socket outlet back boxes are specifically designed for use with plasterboard.

Electrical Terminations

Five types of electrical terminations include:
- Screw terminal: attaches wires using screws.
- Crimp terminal: joins wires mechanically via a crimping tool.
- Soldered terminal: connects using solder for a permanent bond.
- Push-fit terminal: allows wiring connection without screws.
- Insulation displacement terminal: connects wires without stripping insulation.

Electrical Circuit Components

Fuses and circuit components are labeled for easy identification.
Line conductor is colored brown, while neutral conductor is blue.
CPC (Circuit Protective Conductor) is colored green/yellow.

Wiring Diagrams

One-way lighting wiring diagrams can illustrate connections with 2 lights.
Comprehensive diagrams include labeled components such as CCU (Consumer Control Unit), outlets, fuse locations, and conductors.
