Certified Facility Manager (CFM) Practice Exam

A property's distribution and control system splits the electrical supply into:

1. branch circuits

2. feeders

3. main panels

4. transformers

The correct answer is: feeders

In a property's distribution and control system, the electrical supply is split into feeders. Feeders are crucial in electrical distribution as they carry bulk electrical power from the main source, such as the utility, to various sub-distribution areas within a facility. This allows for a systematic approach to manage the electric load and ensures that power is distributed efficiently to different sections of the building. Feeders typically supply power to various locations, where it can then be stepped down further into branch circuits that deliver electricity to specific loads and devices. This layered approach helps maintain safety, manage load effectively, and allow for the organized control of electrical power throughout a facility. While branch circuits, main panels, and transformers play important roles in electrical distribution, it is the feeders that primarily manage the high-capacity electrical supply from the main source to various panels and circuits within a facility. This organization is essential in large facilities where diverse electrical needs must be met safely and efficiently.
