Are conduit fittings marked "raintight" or "wet locations" automatically considered "liquidtight"?

The correct answer is based on the distinction between the terms used to describe different types of fittings and their applicability to the protection of electrical installations. "Raintight" or "wet locations" indicates that a fitting can withstand exposure to moisture or rain without allowing water to enter the electrical enclosures. However, this does not necessarily imply that the fitting can also prevent liquid ingress under significant pressure or from direct immersion.

Liquidtight fittings are specifically designed to provide a greater level of protection against the intrusion of liquids, often featuring gaskets or seals that offer resistance to water and other liquids entering the conduit. Raintight or wet location ratings do not encompass the additional requirements and design specifications of liquidtight fittings.

Therefore, a fitting marked as "raintight" or suitable for "wet locations" cannot be automatically assumed to be liquidtight, as those standards have different performance criteria. This understanding is crucial for ensuring that electrical systems are installed safely and to code, particularly in environments where liquid exposure may occur.
