Electrical installation refers to the process of setting up electrical systems in buildings or structures. This includes wiring, outlets, switches, and lighting fixtures, ensuring they are safely and efficiently connected to the power supply. Proper installation is crucial for the functionality and safety of electrical systems. Qualified professionals, often called electricians, perform electrical installations following local codes and regulations. They ensure that all components are correctly installed and tested to prevent hazards such as electrical fires or shocks. Regular inspections and maintenance are also important to keep electrical systems in good working order.
