Keskusjohdin

Keskusjohdin is a Finnish term that translates to "central conductor" or "main conductor." It refers to a primary electrical conductor in a distribution system or a piece of equipment. In the context of electrical power distribution, the keskusjohdin is the main line that carries electricity from a substation or transformer to various branching circuits or individual consumers. It is designed to handle a significant amount of current and is typically insulated to prevent electrical hazards.

The term can also be used in relation to internal wiring within electrical appliances or control panels. Here, it signifies the principal conductor that distributes power to different components or functional units. For example, in a washing machine, the keskusjohdin might be the wire originating from the power cord that then splits to supply power to the motor, heating element, and control board. The size and rating of the keskusjohdin are crucial for safe and efficient operation, as it must be able to accommodate the total load of the connected devices. Improper sizing can lead to overheating and potential fire hazards.
