Sisäjohdotuksen

Sisäjohdotus, also known as internal wiring or internal electrical wiring, refers to the system of electrical conductors and their associated components that are installed within the walls, ceilings, floors, and other structural elements of a building. This system is designed to safely and efficiently distribute electrical power from the main service entrance to various outlets, switches, lighting fixtures, and appliances throughout the interior.

The primary purpose of sisäjohdotus is to provide a safe and reliable pathway for electricity. It typically involves a network of insulated wires, often copper, protected by conduits or sheathing to prevent damage and electrical hazards. These wires are connected to a distribution board, commonly known as a fuse box or breaker panel, which houses protective devices like circuit breakers or fuses to prevent overcurrents and short circuits.

Components of sisäjohdotus include junction boxes, which provide accessible points for connecting wires, and various types of electrical boxes that house outlets, switches, and fixtures. The installation of sisäjohdotus must adhere to strict electrical codes and safety standards to ensure the integrity of the electrical system and the safety of occupants. Proper planning and installation are crucial to prevent issues such as electrical fires, shocks, and power disruptions.
