What wiring methods must be used when mixing Class 2 conductors with Class 3 conductors?

When mixing Class 2 conductors with Class 3 conductors, the appropriate wiring methods to use are Class 3 wiring methods. This is because Class 3 circuits are generally associated with higher power levels and can carry more current compared to Class 2 circuits.

Class 2 circuits are designed to be limited in their voltage and current to enhance safety and reduce the risk of fire. Therefore, when working with these two classes, the more stringent requirements of Class 3 circuits should be adhered to in order to maintain safety standards and ensure proper function.

Using Class 3 wiring methods ensures that the conductors' capabilities are matched and that any potential hazards from the higher power levels of Class 3 circuits are adequately addressed. This approach also helps in maintaining the integrity of the installation, preventing potential interference or overload situations that could arise from improper mixing of these classes.
