What type of enclosure is constructed to prevent moisture from entering under specified test conditions?

• A. Ungrounded
• B. Watertight
• C. Switchboard
• D. Remote Control Circuit

Answer: (B)

The correct answer is watertight. A watertight enclosure is specifically designed to prevent moisture intrusion under defined testing conditions. This type of enclosure is crucial in various applications to ensure that sensitive electrical components are protected from water, which can cause damage or malfunction. Watertight enclosures are often constructed using materials and design features that create a seal, preventing moisture from penetrating the housing even when submerged in water or exposed to high humidity environments. The testing conditions referenced could include submersion in water for a certain period, exposure to water spray, or other specified scenarios that simulate real-world conditions when moisture exposure might occur. In contrast, ungrounded enclosures do not offer specific protection against moisture; they focus on electrical safety by preventing accidental grounding. Switchboard and remote control circuit options refer to specific electrical configurations or control mechanisms and do not inherently relate to moisture protection. Therefore, the watertight enclosure is the appropriate choice for ensuring moisture does not enter under specified test conditions.
