Which term is the umbrella category that includes equipment such as electrical supply equipment, electrical utilization equipment, electric generating plant, electric supply line and substation?

Explanation:
The main idea is understanding how an electrical system is categorized as a whole. Electrical installations describe the entire installed electrical system at a site, covering generation, distribution, and use of power. That means it includes the electric generating plant, the supply lines and substations, and both the equipment that feeds power into the system and the equipment that uses that power. So all the pieces listed—generating plant, lines and substation, supply equipment, and utilization equipment—fit under this umbrella term because it refers to the complete installed electrical system, not just a single part. The other terms point to specific parts of that system. Electrical supply equipment refers to gear that feeds power but doesn’t by itself denote the whole setup. Electric generating plant is only the power source, and electrical utilization equipment is only the devices that consume power. None of these alone encompasses the full scope, whereas electrical installations do.
