If compression fittings are installed in wet areas, what type must they be?

• A. Heavy-duty
• B. Watertight
• C. Raintight
• D. Standard

Answer: (C)

When compression fittings are installed in wet areas, they must be designed to be raintight, which means they can withstand exposure to water without allowing moisture to enter the conduit or raceway. This is crucial in maintaining the integrity of the electrical system, as moisture can lead to corrosion, conductivity issues, and ultimately equipment failure. Raintight fittings are specifically engineered with seals to prevent water infiltration, making them suitable for outdoor settings or any locations where they might be exposed to rain or significant moisture. This characteristic enhances safety by ensuring that electrical connections remain protected from adverse environmental conditions. While other types of fittings like heavy-duty or watertight may have their applications, raintight fittings specifically address the requirement for protection against moisture in wet environments, ensuring compliance with applicable codes and standards related to electrical installations in such conditions.
