<p>The bases of the boxes (11,11') i.e. the formed extensions, beneath the sockets, have the current carrying conductors embedded in them and insulated from one another. The conductors end in connection bushes or clamps (121) on one side and connection pins or springs (122) on the other, and in addition, have a tap-off in the form of a bush or clamp (123) inside the base. The pick-up connections (121,122,123) are protected by surrounding insulation, the open ends being covered on assembly by a stopper (14) one end and a cap (13) the other. An adaptor (21) with a contact (211) corresponding with the inernal pick-up point (123) is inserted into the pick-up and has its own socket (212) into which the connecting cable of the apparatus (31) is inserted. The installation system is suitable for electrical apparatus arranged in rows, such as switches, socket outlets etc. and can be plastered in after assembly.</p> |
