behavior objectives
Behavior Objectives
  • Define the basics of Electrical Systems
  • Explain the basic principles of Electricity.
  • Describe the different materials used in Home Electrical Systems.
wiring
Wiring
  • Electrical wiring is one of the three installations including plumbing, hearing ,and air conditioning.
  • Electrical wiring consists of wires, boxes, and devices that control the distribution and use of electricity. (wires, boxes, switches)
wiring4
Wiring
  • Electrical wiring powers lights, heating units, and appliances such as refrigerators, ovens and washing machines.
wiring safety
Wiring Safety
  • Personal contact could cause serious injury or even death.
  • An electrical short may cause a fire.

Wiring

This is why installation requires professional installation.

equipment and materials
Equipment and Materials
  • Conductors – These are the wires that carry current from the source.
  • Boxes and Covers – Covers, conceal and protect devices, such as switches and receptacles, placed in boxes in boxes.
  • Switches – Switches control the current to lights and appliances
equipment and materials8
Equipment and Materials
  • Fuses and Circuit Breakers – Protect conductors from overloads, shutting off power to the circuit in case of a fault in the circuit or a too-heavy current draw that would heat up the wire and cause it to fail.
  • Receptacles (outlets) – Allows convenient connection of appliances and lights to a circuit.
  • Conduit– Pipes or enclosed channels through which conductors are run
  • Connectors – Secure connections between two or more conductors and conduit.
electricity
Electricity
  • Electricity – is the flow of electrons in a conductor. (measured in amps)
  • Electrical Current – the force applied in order to achieve the flow of electrons.

Electricity
  • Direct Current – Current flows in one continuous direction. (ex. Battery)
  • Alternating Current – The process of rapidly changing the direction of voltage. (ex. Home circuits)
services
Services
  • Substation – a series of transformers that step down voltage before it is delivered to a large number of customers.
  • Step-Down Transformer – Each building has a step-down transformer to further step down the voltage.
electrical circuits
Electrical Circuits
  • Electrical Circuit – a complete path for current to flow.
  • Source – provides the electric energy to the circuit.
  • Conductor – the path for the electric energy.
  • Load – Utilizes the current to perform a useful purpose
  • Control Device – A device used to perform a certain task.
