Abstract: For the communications and data transfer wiring of a modern office building the invention provides a prewired cable trunking module with a number of socket outlets along its top surface. The module has a flat cable extending through the duct, sets of wires being split off the cable at intervals to connect with the outlets. Successive modules can have a single continuous cable extending through them, or can be connected by multiway connectors at each end of each module.

Abstract: A conduit having socket positions spaced along its length comprises a rear member 50 secured to a wall, a cover member 10 attached to the rear member and an elongate insulating member 30 which prevents conductors 70,71,72 from being exposed when the cover member is detached from the rear member. The insulating member 30 may be attached to both members 10 and 50 with the attachment to the cover member 10 being stronger than the attachment to the rear member 50. The pins of an electrical plug pass through openings in the cover member to electrically contact the conductors 70,71,72.
