The Basic Components of Your Home's Electrical Wiring System

Your home's electrical wiring system comprises several basic components that work together to power your appliances and devices. The main components are:

Service Panel: All power enters your home through the service panel, which is its main entry point. It has fuses or circuit breakers that guard against electrical overloads in your home.

Circuit Breaker: Circuit breakers are safety mechanisms that turn off the power supply immediately if the electrical current exceeds permissible limits.

Wiring: is the system of wires that are used to transfer electricity to various outlets and appliances around your home.

Outlets: Electrical outlets are the points where you can connect your appliances and devices to the electrical wiring in your home.

Signs of Electrical Wiring Problems
