A fault condition monitoring apparatus for use with a fuse cutout includes
a housing operable to be supported by the fuse cutout. The housing has
first and second contacts operable to make electrical contact with fuse
contacts on the fuse cutout when the housing is supported by the fuse
cutout. A current sensor is mounted inside the housing and is connected
to the first and second contacts. A signaling device is coupled to the
current sensor and is operable to cause a signal to be produced when
current sensed by the current sensor meets a criterion.
