What action should be taken for conduits or raceways through which moisture may contact live parts?

When conduits or raceways are exposed to moisture that could potentially come into contact with live parts, it is essential to implement protective measures to ensure safety and compliance with electrical standards. Sealing or plugging open ends can effectively prevent moisture intrusion, which helps avoid electrical shorts, corrosion, and hazards like electrical shocks or fires.

Sealing involves using appropriate materials or techniques to close off the conduit or raceway, thereby creating a barrier against moisture. This is particularly important in outdoor applications or in environments where condensation may occur.

Plugging is a similar action where the ends of the conduits are fitted with plugs that prevent the entry of moisture. This solution is practical for ensuring that the internal components remain dry and free from the risk of electrical failure.

Choosing either sealing or plugging is vital in these situations, as both methods achieve the goal of protecting electrical systems from moisture damage, which is essential for maintaining system integrity and safety in environments susceptible to moisture exposure.
