In a first embodiment, the first base 54 is no longer part of the plug assembly 5, but is arranged between the second base 74 and the second cover 12, as a basis for the installation of the pins, which are electrically connected in a relatively fixed manner to the corresponding conductor tracks.

Latch panel 202 is disposed between first base 54 and second cover 12 and is rotatable relative to second cover 12. Each latch is secured to the latch faceplate 202 and extends through the second cover 12 at least partially out of the second cover 12, whereby each latch is connectable directly to the mains power supply, such as by being plugged into a wall mounted faceplate socket. The latch panel 202 is fixed to the first base 54, and each latch also passes through the latch panel 202 and the first base 54 to slidably engage with each conductor rail in the second base 74, i.e., the L-pole latch 2011 corresponds to the L-pole conductor rail 71, the N-pole latch 2012 corresponds to the N-pole conductor rail 72, and the ground pole latch 2013 corresponds to the ground pole conductor rail 73, each latch being slidable along the corresponding conductor rail.
