True or False: An enclosure that is weatherproof only when the receptacle cover is closed may be used in a wet location for portable tools while attended.

True
False
Only if attended
Only if the tools are unplugged

The correct answer is: True

The statement is true because a weatherproof enclosure can provide adequate protection from moisture and environmental conditions when the receptacle cover is closed. This means that the enclosure is designed to prevent water ingress during its intended use. If the tools are being used while attended, the risk of water entering the enclosure when it is open is mitigated by the presence of an individual monitoring the situation. However, it is essential to ensure that while the receptacle cover is closed, it indeed meets the code requirements for safety in wet locations. It's important to consider that although the cover needs to be closed to maintain the weatherproof integrity of the enclosure, having an attended operation involves direct supervision by the user, ensuring that any potential issues can be addressed immediately. This makes the use of such an enclosure permissible in wet conditions as long as proper protocol is followed.
