Understanding Electrical Circuit Breakers And Panels
The main panel includes a mechanical device to disconnect a home’s electrical circuit breakers incoming power. These devices are known as electrical circuit breakers. The breakers are switches that allow you to manually turn off or will automatically trip upon failure in an electrical system, usually when overloaded.
There are many different types of electrical breakers. Today, most homes have individual breakers with switches that allow you to control them by flipping a switch. When the temperatures of electrical circuit breakers become too hot, the switch will trip and shut off the power as a precautionary measure preventing a fire. Some types of circuit breaker panel use levers and even fuses. You will pull a lever down or be required to remove a fuse block to turn off the power to the circuits in the home.
The maximum amount of amperage an electrical panel can be delivered at once is usually marked on the primary breaker. Most homes only need a 100-amp main and it will be sufficient enough to handle any electrical needs. It is common for new home builders to install 200-amp breakers today to ensure increasing needs of homeowners. Panels that are rated at 60 amps are small and undersized for less electrical needs. If you have a small panel like this and use a lot of electricity, you may need to upgrade the panel in your home.
Electrical circuit breakers are rated for the load required and the type of wire by the circuit. The typical capacity for lighting a home is 20 or 15 amps. The standard circuit breakers for 120 volt circuits utilize one slot. If you need 240 volts, you will utilize two slots. It is common for some manufacturers to design thin breakers which take only have of the space as a standard breaker.
The larger capacity circuit breakers like the Commander are designed for electric appliances like stoves, clothes dryers, water heaters, air conditioners, and other things that draw a large amount of power. You can also use a large breaker to connect a secondary panel, which will have its own set of breakers. A subpanel can be located in a different section of the home.
Electrical breakers for the kitchen, outdoors, and the bathroom require ground fault circuit breakers interrupters. These are designed to guard against electrocution. This is because these areas are around water and sensitive to shorting. It is common to be required to reset this breaker more frequently. It is a good idea to test a GFCI breaker as they are used.
The electrical circuit breakers in a home are designed to provide power throughout. Breakers are designed to provide power to specific appliances and even different areas of the home. Depending on the different amount of voltage or amperage needed in the home, will determine the type of panel you need and the breakers. You can have more than one electrical panel in a home to manage the electricity. A second panel is called a subpanel and it can be placed on the other side of the home. This can make management of electricity much easier.
