What type of enclosure is required for a 125 volt, 15 ampere rated receptacle installed outdoors in a wet location?

A 125 volt, 15 ampere rated receptacle installed outdoors in a wet location must be housed in a weatherproof enclosure. This is essential to ensure that the receptacle is protected from moisture, rain, and other environmental conditions that could potentially cause electrical faults or shorts. Weatherproof enclosures are specifically designed to prevent water ingress while allowing for safe electrical connections, making them suitable for outdoor use.

While dustproof enclosures are useful for protecting against dust and debris, they mainly do not address moisture concerns. Water-resistant would imply a lesser degree of protection that may not adequately safeguard the receptacle in heavy rain or wet environments. Corrosion-proof enclosures focus on preventing deterioration due to exposure to corrosive substances but do not ensure protection against water ingress. Therefore, the weatherproof designation is both necessary and appropriate for installations in wet locations, ensuring the safety and functionality of the receptacle.
