The electrical installation system is a process of distributing electrical power generated from an electric power source to electrical devices or loads. The main purpose of lighting electrical installations is to provide comfort in situations that require accuracy, lighting that has a high intensity is needed, while for jobs that require accuracy, there is no need to use lights that have a large brightness. The installation is divided into two parts, namely electrical power installation and lighting installation. Indoor installations are electrical installations inside buildings (including for lighting, terraces and others) while installations outside buildings are installations used to run electrical machines including here installations to service electric motors in factories, water pumps, etc., on machines.
