1. What is an Electrical System?

An electrical system in a building consists of:

• Power supply lines – Bring electricity from the main grid

• Wiring and cables – Distribute electricity to all areas

• Switches and outlets – Control and access electrical power

• Protective devices – Fuses, circuit breakers, and earthing systems

• Lighting and appliances – Utilize the electrical supply efficiently
