Zusammenfassung:	Apparatus (15) for monitoring power consumed from anywhere along the conductors (11) in an ac power distribution system (1) includes a housing (21) with through passages (27) through which the conductors (11) extend. Toroidal coils (33) mounted within the housing (21) concentrically with the through passages (27) sense the current in the conductors (11). Elongated electrically conductive screw fasteners (45) threaded into support blocks (39) mounted on a printed circuit board (35) within the housing (21) extend radially into the through passages (27) to penetrate insulation (53) on the conductors (11) and to electrically contact and mechanically clamp the conductors (11) thereby simultaneously providing a voltage tap and locking the housing (21) to the conductor (11).
