FEED
A power supply to a piece of equipment or installation is termed a "feed". Sound equipment and sensitive computer equipment should have a clean feed - that is, a supply that is free from interference from other equipment.

FEEDER
A main power cable to an installation is known as a feeder.

• The cable which feeds or supplies power to a dimmer rack. Feeder cable is usually heavy gauge cable capable of safely carrying the hundreds of amps necessary to supply as many as 96 individual dimmers in a rack. Feeder cables are usually connected via Camlock connectors. A bare-end or tail often connects one end of a feeder to the power supply or company switch.
