The correct answer is: D. All of the above
A feeder is a conductor that carries electricity from a power source to a distribution system. It can feed power to distributors, generating stations, and service mains.
- Distributors are companies that own and operate the power lines that deliver electricity to homes and businesses.
- Generating stations are facilities that produce electricity.
- Service mains are the power lines that connect a home or business to the distribution system.
Feeders are typically made of aluminum or copper and are insulated to prevent electrical shock. They can be either overhead or underground. Overhead feeders are supported by poles, while underground feeders are buried in the ground.
The size of a feeder depends on the amount of power it needs to carry. Feeders that carry more power are typically larger and have thicker insulation.
Feeders are an important part of the power grid. They ensure that electricity is delivered safely and reliably to homes and businesses.
