It is aimed to provide a fuse holder with a novel structure capable of improving insertion operability in the fuse holder for holding a plurality of fuses. A plurality of fuse holding portions (26a, 26b) are provided into which main body portions (16, 16) of fuses (12a, 12b) are to be mounted and in which lead portions (14, 14) of the fuses (12a, 12b) are held in a projecting state. Holding positions of the fuses (12a, 12b) by the plurality of fuse holding portions (26a, 26b) are made different from each other in a projecting direction of the lead portions (14) from the main body portions (16) in the fuses (12a, 12b).

A power circuit interrupting device including a first housing including a pair of fixed electrodes and a fuse having terminals at both ends thereof, and a second housing including a moveable electrode, the moveable electrode interrupting electrical connection between the fixed electrodes when the second housing is uncoupled from the first housing, and establishing the electrical connection between the fixed electrodes when the second housing is coupled with the first housing. The first housing has an opening provided for carrying out a continuity test for the fuse. The opening is always covered with the second housing in a condition that continuity of a circuit is allowed. The power circuit interrupting device serves to facilitate the continuity test for the fuse built therein and comply with such a maintenance procedure that the continuity test should be carried out after interrupting continuity of the power circuit.

A power distributor including a first conductive coupling device electrically coupled to a bare-wire non-terminating section of a first conduit. A second conductive coupling device is electrically coupled to a terminating end of a second conduit. The first conduit is a larger gauge than the second conduit. A fuse electrically connects the first conductive coupling device and the second conductive coupling device. A housing encases the first and second conductive coupling devices and the fuse.

A device for monitoring and indicating a fuse tube detachment from a fuse cutout assembly contains a structural body, a tilt switch, a power source, a visual indicator, and an attachment mechanism. The attachment mechanism is used to mount the device onto the fuse tube. The tilt switch monitors the position of the fuse tube. More specifically, when the vertical position of the fuse tube changes to the dropped position the tilt switch is triggered. Thus, the visual indicator is illuminated. The illumination aids in the process of discovering the detached fuse tube. In addition to the visual indicator, the device can also be equipped with a wireless communication device and an alarm system. The wireless communication device can be used to provide the exact location of the detached fuse tube. On the other hand, the alarm system can be used to expedite the process of discovering the detached fuse tube.
