Electrical Equipment

Electrical equipment is used to connect, supply power to, switch, and control electrical components within other equipment. Depending on its purpose, an item may serve an installation, connection, control, or power-supply function. The appropriate type depends on its role and position in the electrical system.

Important selection criteria include operating electrical parameters, connection and mounting methods, and compatibility with the other components. Conditions of use must also be considered, including proximity to heat sources, possible exposure to moisture or dirt, enclosure protection requirements, and access for maintenance.

An item must correspond to the connection scheme and the function of the specific component. Installation should account for the equipment manufacturer's requirements and the expected nature of the load, since electrical items that look similar may differ in operating principle and permitted conditions of use.
