An Electrical Panel is the section in the power distribution system where the power feed is divided into discrete circuits. Conventional Electric Panels consist of a main switch, a protective fuse corresponding to each circuit and a number of Residual-current Devices (RCD). Electrical Panels play a pivotal role in power distribution throughout commercial as well as residential buildings.
Available in various sizes, an Electrical Panel houses a number of electrical components including meter devices, protection devices such as fuses, transformers and conductors. All these components are systematically and logically arranged to ensure an efficient power distribution system. Depending upon the construction and application, Electrical Panels can be broadly classified into following two categories:
Lighting & Appliance Electrical Panels:
Mostly applicable for residential purposes, Lighting & Appliance Electrical Panels consist of receptacles, lighting equipment, small loads, etc.
Power Electrical Panels:
Power Electrical Panels are considered apt for commercial applications.
Construction Of Electrical Panels:
Electrical Panels are available in various grades and specifications but the basic construction remains the same. The structure of the Electrical Panels consists of two main parts, namely the can and the interior. Made up of galvanized steel, the can houses the internal components of the Electrical Panel. Additionally, it acts as the supporting framework for the Electrical Panel allowing it to be installed properly.
Besides, the can plays a vital role in the protection mechanism by providing electrical grounding to the whole arrangement. In the event of short circuit, the grounding of the metallic can allows the current to flow into the earth thus preventing the damage of the circuits.
Rating Of Electrical Panels:
A number of characteristics are taken into account while rating an Electrical Panel. Primarily, the type of Electrical Panel and the type of the components are considered of paramount importance for ranking. Several factors such as voltage, wire, phase, etc. are evaluated. There are different rating methods used.
Electrical Panels Enclosures:
Safety should be the priority while dealing with electrical systems and equipment. It is for the same reason that due care is given to the enclosures of Electrical Panels. There is a wide variety of enclosures available. Irrespective of the specification, the enclosure should offer protection against rain, dust, heat and mechanical shocks.
The brief information regarding the Electrical Panels will certainly guide you in getting the best one as per your requirement.
