Type AC cable is permitted for which purpose?

1. For branch circuits

2. For feeders

3. For service-entrance conductors

4. For direct burial

The correct answer is: For feeders

Type AC cable is specifically designed for flexible residential and commercial wiring applications and is typically permitted for branch circuits, which makes it suitable for powering outlets and devices within a building. It is especially effective in environments where flexibility and ease of installation are important. When considering the cables that are typically used for feeders, Type AC cable can be utilized to connect the service equipment to the branch circuits. This is because feeders are essentially the conductors that carry power from the service equipment to the branch circuit, so they need to handle a reasonable load and should be protected against potential hazards. While Type AC cable can be used for branch circuits, its use as service-entrance conductors is restricted due to the requirements for greater durability and protection at the point where power enters a building. Similarly, Type AC cable is not suitable for direct burial due to the need for special protection against moisture and harsh environmental conditions. Thus, the application of Type AC cable is best aligned with its intended use in branch circuits and feeders under the right conditions. This context highlights that while Type AC cable has its limitations, it remains a valuable option for a variety of installations, particularly in situations requiring flexibility and ease of access.
