ABSTRACT:
A dynamic fuse testing device includes an elongated handle, a head pivotally mounted to the handle, a fastener for tightening the head relative to the handle to place the head and handle at a desired angular position relative to one another, a pair of elongated electrically conductive test probes for contacting opposite ends of a fuse, a pair of mounting members attached in spaced relation to one another on the head, the mounting members having respective outer ends mounting the respective probes, one of the mounting members being stationarily mounted on the head and the other of the mounting member being rotatably mounted on the head such that its outer end is pivotally movable toward and away from the outer end of the one mounting member for adjusting the distance between the probes to accommodate fuses of different sizes, and a lamp and battery on the head connected in series with the probes such that the lamp is illuminated by contact of the probes with a properly functioning fuse.
