What Is an Electrical Control Panel?

Electric control panel is a metallic box that gives the person full access to all electric equipment, appliances, and circuits mechanically by using electricity. This allows the operator to monitor and clear issues within the electric power system.

The electrical current that runs your home begins its journey in a large power plant. It travels over long distances through high voltage wires-the tall towers that disturb many a homeowner’s view out their windows-through local transformers, those big “cans” you might see on utility poles, to your home’s meter and then into your breaker box. Then it flows down two columns of breakers, each rated for how much current it can safely carry (a house typically has 100A of service).

Each breaker switch is set to the “on” position and monitors electrical flow to its assigned space in your home. If too much current is drawn by appliances in that space, the breaker will trip to cut off the flow and avoid an unsafe condition such as an electrical fire. The main breaker switch, which is usually marked with an amperage rating of 200 amps, will also trip if too much energy is drawn across your entire home.

Other components of an electrical control panel include surge arresters that prevent lightning strikes and utility power surges from damaging the circuits inside the panel; terminal blocks, which organize and distribute the array of wires coming in from various sources to different electrical devices; and a Programmable Logic Controller, which is a computer that controls all other electrical components by following preset logic and conditions given to it by operators. The enclosure that houses these components plays a crucial role, protecting them from the elements: water, dust, and other hazards. Electrical Panel
