An electrical installation is the physical infrastructure that delivers electricity to a building or structure. It includes the electrical wires, cables, switches, outlets, and other equipment that are necessary to power the lights, appliances, and other electrical devices in the building.

There are two main types of electrical installations: commercial and residential.
Residential electrical installations are smaller and less complex than commercial installations. They typically use standard equipment and materials, and they are designed and installed to meet the needs of the home’s occupants.

If you are considering having an electrical installation done, it is important to hire a professional electrician. A professional electrician will have the knowledge and experience to properly design, install, and maintain your electrical installation. They will also be able to help you choose the right equipment and materials for your needs, and they will ensure that your installation meets all applicable codes and regulations.
