The distribution panel, load center, control and protection panel or general switchboard, is one of the main components of the electrical device, which is divided in each different circuit by the fuse, the magnetic thermal protection and the distributor protection device. As is the case in most homes, each installation has at least one main panel, being able to be supplied power from this or more auxiliary panels, which is usually the case in industrial installations and large stores. In short, it is the guardian of your home and business. If you have something connected to the power supply, I assure you that it comes from an electrical panel.

Fundamental characteristics of an Electrical Cabinet

Electrical cabinets usually come in many different categories depending on the application for which they are intended. We can find cabinets for houses, garages, swimming pools, industry, etc… In each of these applications the same characteristics are not taken into account to select the cabinet to be used and it is necessary to see all the specific requirements of the project for its correct sizing, selection and subsequent assembly and commissioning on site.

    It’s interesting to know about electrical cabinets and how each structure requires a specific type. We decided to build our house from scratch last year, and we’re looking for electrical supplies to design our system, so my wife and I think your article will help us. Thank you for describing electrical panels and how they protect our house’s electrical panel.
