Implementations of the invention relate generally to an electrical feed, in particular a CEE feed, for the external supply of electrical power to the power supply system of a mobile load, in particular a mobile home or a recreational vehicle or a boat. This feed can include a) a flange for attaching the feed to and/or in a wall of the mobile load, and b) at least one feed connector for making electrical contact with a coupling, in particular a CEE coupling. Implementations of the invention can make provision for the feed connector to be arranged in the flange in a rotatable manner.
