ABSTRACT:
An apparatus for use in a power distribution system including an assembly with a support having an electrically conductive portion and an arm pivotally mounted to the first support for movement between a closed position and an open position. The arm has a conductive portion which is adapted to be electrically connected to one of a power source and a load and which is spaced from the conductive portion of the support both when the arm is in its closed position and when the arm is in its open position. The assembly further includes a spring biasing the arm to its open position, and a fuse electrically connected between the conductive portion of the arm and the conductive portion of the support. The fuse retains the arm in its closed position against the bias of the spring. When current flow causes the fuse to blow, the spring biases the arm to its open position thereby providing a visual indication that there is no current path from the source to the load.
