2116008 9304514 PCTABS00020 Electrical supply equipment comprises a circuit breaker comprising a housing (2) having generally flat, parallel side faces provided on the underside with a mounting recess (4), for mounting on a mounting rail of the conventional "top hat" section, comprising a base (7), spaced parallel flanges (8) extending from the base, and parallel outwardly extending flanges (9) which together provide a support surface which may be engaged by an underside of the recess (4). Extending from the underside of the circuit breaker at right angles to the plane of the base is a contact member (22). A supply assembly (28) comprises an elongate housing (30) within which an elongate bus-bar (32) is located, the bus-bar being provided with spaced intervals with spring clips (34). The housing (30) comprises a cover (36), provided at spaced intervals, corresponding to the spacing between the spring clips (34), with apertures (38). A supporting assembly comprises end housings (150), onto which the ends of the mounting rail are press-fitted, the housing also providing a support for the supply assembly, so that the supply assembly extends alongside, and generally below the mounting rail. In the use of the invention, a circuit breaker may be mounted on the mounting rail, the contact member (22) thereof passing through one of the apertures (38) of the housing (30) into engagement with the bus-bar (32) being pressed into face-to-face contact therewith by one of the spring clips (34). Additionally, equipment other than circuit breakers may similarly be mounted on the mounting rail, for similar engagement with the bus-bar, and ancillary equipment which does not need to be connected to the bus-bar may be mounted on the mounting rail, and by virtue of the relative position between the mounting rail and the supply assembly, this may be accomplished without disturbance to the position of such ancillary equipment by the position of the bus-bar.
