Electrical Distribution Systems
The main wires from the electric utility deliver power to your home through the meter. From the meter, power flows through large circuit breakers on the main panel that turn the utility power on or off. When the main breakers are in the on position, electricity flows on to electrical distribution panels. From these panels, individual circuit breakers deliver electricity to the various outlets, switches and appliances throughout the home.
Circuit breakers vs Fuses
How they work
- Find your main panels and sub panels so you know where they are located in the home and label them.
- Inspect the individual breakers for proper labels.
- Inspect for damaged areas, gaps or openings in the panel or around the breakers. Have an electrician make repairs.
- I am not aware of any maintenance or repair procedures that are formally recommended by the manufacturers of circuit breakers.
- Every 3 years: Inspection of the distribution panels and subpanels. The breakers and panel assemblies are subject to corrosion and the effects of heating/cooling. Intrusion of insects and animals into the interior of the panel enclosures can also cause problems. These things could affect proper operation. So it is advisable to have a licensed electrician inspect the interior of the panel and test the breakers. Have an electrician torque all wire connections to manufacturers specified tightness.
