The paper wrap and bonding strip are two features that distinguish Type AC cable from other metal jacketed cables.
A: True
B: False
The correct answer and explanation is:
The correct answer is A: True.
Type AC (Armored Cable) is a type of electrical wiring commonly used for residential and commercial installations. It is designed with a protective metal armor around the individual conductors, which provides physical protection against damage and also shields the conductors from external interference.
Two distinguishing features of Type AC cable are the paper wrap and the bonding strip.
- Paper Wrap: This feature is used to separate the conductors from the metallic armor. The paper wrap ensures that the individual wires inside the cable are insulated from the metal armor, preventing short circuits or electrical faults that could occur if the wires were to come into direct contact with the metallic sheath. The paper also provides some level of moisture resistance, protecting the cable in environments where humidity could be a concern.
- Bonding Strip: The bonding strip is another important feature of Type AC cable. It is a metal strip that runs along the length of the cable and is attached to the metal armor. The bonding strip serves as a grounding path for the cable, ensuring that any stray electrical current that might be carried by the armor is safely directed to ground. This is an essential safety feature as it reduces the risk of electrical shock or fire hazards if the armor were to become energized due to a fault.
These two features, the paper wrap and the bonding strip, set Type AC cable apart from other metal-jacketed cables, such as Type MC (Metal Clad) or other armored cables, which may not include these specific design elements. The paper wrap provides insulation between the conductors and armor, while the bonding strip ensures grounding and enhances safety.
