In what scenario is Type AC cable NOT suitable?

1. For indoor residential wiring

2. For feeder application

3. For grounded circuits

4. For portable devices

The correct answer is: For portable devices

Type AC cable, also known as armored cable, is primarily designed for specific types of wiring applications where durability and protection from physical damage are needed. In scenarios involving indoor residential wiring, feeder applications, and grounded circuits, Type AC cable is often suitable due to its robust construction, which includes a metal armor that shields the conductors from mechanical injury and enhances its grounding capabilities. However, Type AC cable is not ideal for portable devices. Portable devices typically require flexible cabling that can withstand frequent movement and bending without damage. Type AC cable is relatively stiff and not designed for flexibility, making it unsuitable for applications where cables need to be moved or manipulated regularly, such as with portable tools or equipment. Therefore, in the context of utilization with portable devices, a more flexible and lightweight cable type would be necessary to ensure safe and effective operation.
