Electrical Panel is a group of electrical components which are connected together and supply or cut off the electricity to a particular circuit or to a whole system. The components of an Electrical Panel includes Switches, circuit breakers, relays, resistors, capacitors, transformers, and motors. The main function of the panel is to protect the equipment from hazardous conditions such as arcing, overvoltage, and short-circuits, by detecting them and acting on them.
In homes, the Electrical Panel is located in a garage, basement, or utility closet and contains circuit breakers that control power to each space of the house. In the past, these areas of the house were protected by round, screw-in fuses that had to be replaced when they “blew.” Newer panels are equipped with circuit breakers which can be turned on and off with the flip of a switch.
The panels are usually surrounded by an enclosure which is a metal box that keeps the components inside safe from hazards such as impact, heat, dust, and liquids. The enclosures also offer protection from electromagnetic interference (EMI), which reduces the chances of electrical shock or fire.
Most panels have push buttons or pilot lights that get used by the operators to give inputs on the status of the panel. Some examples include the emergency stop red mushroom head push button and MCR reset push buttons. The push buttons are usually placed in the door of the panel with a visual indicator to show the operator that something is wrong or needs attention. Electrical Panel
