Which term includes all components used in electrical installations?

The term "Equipment" encompasses all components used in electrical installations, which may include various systems and devices that are integral to the electrical setup. This includes everything from large machinery and appliances to the wiring and connections that ensure the electrical system operates safely and effectively.

In the context of electrical installations, equipment is a broad category that captures not only the major electrical devices like generators, transformers, and motors but also smaller components like controllers, panels, and storage media. This comprehensive definition makes it clear that the word "equipment" applies to the complete range of items necessary for the design, operation, and maintenance of electrical systems.

While other terms may refer to specific subsets of components, "apparatus" typically signifies machinery or devices designed for a specific function, which is more limited in scope. "Devices" often refers specifically to individual items with distinct functions, such as switches or sensors, and "fittings" are usually used to describe connectors or mechanical components that help in establishing electrical circuits. Therefore, "equipment" is the most inclusive term for all components in electrical installations.
