A power inlet box suitable for outdoor or external use is configured in such a manner that an electrical socket may be electrically coupled to an interior load before the electrical socket is secured within the power inlet box. The power inlet box may be formed from weather or otherwise corrosion resistant material such as plastic and is designed such that the electrical socket faces downward toward an exposed lower end of the power inlet box. The electrical socket is supported by a mounting member that may be removably mounted to the power inlet box to secure the electrical socket within the power inlet box.
