A hinge for transferring power between a wall jamb and a door. The hinge includes a pair of hinge leaves having interleaved knuckles axially aligned to share a common bore and engaged to allow the door to rotate. At least one cable enters a recess in a rear surface of one hinge leaf, passes through a longitudinal passageway in the hinge leaf, across the common bore, through a longitudinal passageway in the other hinge leaf, and exits a recess in the rear surface of the other hinge leaf. The passageways are aligned or accessible from the common bore and have tapered openings to enable the cable to be routed or fished after the hinge is mechanically assembled.
