  • Disconnect splice block and modular surge device
    Patent number: 9825459
    Abstract: An electrical coupling device, such as a surge protector for a rail or other conductive structure, includes a pair of terminals, and a jumper for selectively electrically coupling and decoupling the terminals. Movement of the jumper may expose part of the jumper or one or both of the terminals, such as for use as a test point. A surge module with one or more surge protection features may fit into a base that includes the terminal and the jumper. The module may have an interface feature, such as a protruding post, that prevents engagement with the base if the base is not properly engaged with the rail or other structure. In one embodiment, a threaded rod may serve as the jumper and in one position electrically couples the terminals and in another position electrically decouples the terminals and one end of the threaded rod becomes exposed for use as a test point.
