Electrical Control Panel
Electrical Control Panel
An electrical control panel is a metallic box that allows the person to control all electric equipment, appliances, and circuits mechanically by using electric energy. It gives an operator full access to the whole electric system of a specific location within one large electric board, and with that access, operators can monitor and maintain the entire electric power system. An electrical control panel provides the fastest and easiest method of troubleshooting and clearing issues, and multiple protection devices within an electrical control panel give safety to the whole power system of a specific power system.
Electrical Control Panel – Structural Components
The structure of the electrical control panel gets designed in a way to house maximum electric equipment within its boundaries, keeping all running systems safe. There are two fundamental structural components of this type of panel. They are:
The Enclosure
Enclosure in the control panel plays the role of its body, which is a metallic box made mostly either from aluminum or stainless steel. Its job is to house all equipment within it and provide electrical safety to the equipment from outdoor conditions, where its size depends on the required job. The enclosures have printed plate that shows the specification of the usage limits for the electric control panel, such as whether it could get used for indoor applications or outdoor applications, waterproof, dustproof, hazardous condition rating, and explosion-proof rating. These ratings get decided by the NEMA classification of the electrical control panel after safety and IP testing.
The Back Panel(s)
The back panel is a metallic sheet housed inside the enclosure that provides actual housing and connectivity to electric equipment in an electrical control panel. It either has mounting holes, or one can drill holes for fitting-in electric equipment. DIN rails are an essential part of the back panel that provides housing and fitting structure for electric equipment that gives structural support within the enclosure. Another crucial component in back panels is wire ducts that allow connectivity of equipment with electric power in a mannered way and makes the process of maintaining and troubleshooting easier by giving a clear view of conductor lines.
Wire Ducts and Din Rail
The wire ducts are usually made of plastic. They have either wide or thin fingers on the sides that allow wire to exit and be connected to an electrical component. A removable lid is snapped to the top to protect and hide the wire runs underneath to give the electrical panel a clean, finished look.
Din Rail is a metallic strip used to hold many electrical components. Components easily snap on and can slide on the rail to any position required. This is a time-saving item so that each component does not need to be individually mounted to the back panel.
