    摘要： A fused disconnect switch including a plurality of maintenance and installation enhancing features is disclosed. For example, a bipolar LED is provided as an alarm indicator so that the fused disconnect switch will function in power distribution systems which operate on both positive and negative voltages. Additionally, a manual test tab is provided for checking the alarm circuitry and a viewing window is provided so that the presence or absence of a fuse in the fused disconnect device can be ascertained without removing the fuse holder.

    摘要： A hammer head training target for enhancing the level of training by training realistically and effectively with a life-like target head. The inventive device includes a life-like resilient foam head having an integral oval-shaped handle and a core insert clamshell encasing that traps the handle in place. The head resembles the head of a human being with eye, ear, nose, mouth and temple features. An opening is provided in the back side of the head for access to the handle. The handle is oval in shape and is strategically located at the centroid of the head for optimum angle position for the trainer's hand. The handle is sandwich between the left-hand and the right-hand core insert encasings. The left-hand core insert captivates half of the handle structure. It contains half of the enclosure for protecting the hand during training. The right-hand core insert captivates half of the handle structure. It contains half of the enclosure for protecting the hand during training.

    摘要： A fused disconnect device constructed according to the present invention comprises a housing, a line side terminal, a load side terminal, a protection fuse holder assembly removably installed in a cavity of said housing, and a separate alarm fuse removably installed in said housing. The alarm fuse may remain installed in the housing regardless of the presence of the protection fuse holder assembly, so that an alarm will be generated whenever the inventive device has interrupted power to the load. In a first embodiment of the invention, the disconnect device is adapted for front-access mounting in a power distribution panel. In a second embodiment of the invention, the disconnect device is adapted for rear-access mounting in a power distribution panel. A third embodiment is adapted for use in higher-current applications.
