There is provided a weather resistant power outlet (GPO) of the type including a double socket assembly having rocker switches and female prong contacts and supported on the back of a mounting plate having respective insulative prong apertures. A space exists between the mounting plate at the prong apertures and the female prong contacts, providing a safety gap between the apertures and the contacts. An elastomeric body is located in the space and compressed against the mounting plate by the socket assembly. The elastomeric body has prong-passing slits allowing passage of prongs of an electrical male plug passing through the prong apertures to electrically engage the female prong contacts, the openings being self-sealing on withdrawal of the prongs under the resilient bias of the elastomeric body. The GPO is rendered weatherproof without increasing the mounting plate to female contacts distance.
