What characteristic defines a watertight enclosure?

• A. It is operational in high moisture areas
• B. It is impervious to water under specific conditions
• C. It can function without being connected to ground
• D. It prevents exposure to the weather

Answer: (B)

A watertight enclosure is defined by its ability to be impervious to water under specific conditions. This characteristic ensures that no water can penetrate the enclosure, which is crucial for protecting electrical components and other sensitive equipment from moisture that could lead to malfunctions or safety hazards. The standard for watertight enclosures often takes into account factors such as the pressure against the enclosure and the duration of exposure to water, confirming its effectiveness in preventing leaks. The other characteristics mentioned are relevant but do not capture the defining trait of a watertight enclosure. For example, being operational in high moisture areas is important, but it does not specifically indicate the enclosure's water resistance. Functioning without being connected to ground pertains to electrical safety but does not relate to the watertight capability. Lastly, preventing exposure to the weather is a broader concept; it might refer to other protective measures but does not specifically emphasize the watertight quality under defined circumstances.
