What procedure must be used when passing all conductors through bulkheads and/or partitions?

The procedure that must be used when passing all conductors through bulkheads and/or partitions is to employ grommets and cable clamps to prevent chafing. This is important as grommets help to protect the insulation of the conductors from wear and damage caused by friction against the edges of the holes through which they pass. Additionally, cable clamps serve to secure the wires in place, preventing them from moving around and potentially getting damaged or causing short circuits.

Using grommets creates a smooth interface through which the wires can pass, mitigating the risk of abrasion that could lead to insulation breakdown over time. This ensures the longevity and safety of the electrical system within the RV. Preventative measures like this are crucial for maintaining the integrity of electrical systems and avoiding potential fire hazards or electrical failures.
