Which type of wiring methods should not be installed in the same cable or raceway as power limited firearm conductors?

The correct choice is Class II wiring methods. Class II circuits are defined by their limited power output, which helps to minimize the risk of electric shock and fire. These methods are generally considered to be lower in risk compared to Class I and Class III wiring methods. However, when it comes to intermingling conductors with power limited firearm conductors, Class II wiring has specific restrictions.

Class II circuits are designed for safe operation under normal conditions, but their installation in the same cable or raceway as power limited firearm conductors could pose a risk. This is because power limited firearm conductors may carry different voltage and current levels, and fault conditions affecting one type of circuit could adversely affect the other.

In standard electrical design and safety practices, maintaining separation between Class II wiring and other types ensures that there’s no risk of electrical interference, increased load, or fault conditions that could compromise the functionality or safety of either system. Hence, adhering to this separation is critical to maintaining system integrity and safety codes.
