Abstract: A modular fuseblock furnishes dovetail joint grooves and ridges that are accessible from above on both sides of the fuseblock. This provides for interlocking or joining additional fuseblocks on either side of a panel mounted fuseblock without unfastening the mounted fuseblock. Pilot grooves and ridges extending upwardly respectively from the dovetail grooves and ridges aid in engaging the dovetail groove and ridge joint means. Locking tabs on the sides of the fuseblock body detent joined fuseblocks to maintain them fixed in vertical position and end walls that ride in vertical tracks in the two side walls of the fuseblock prevent intrusion to the fuse clips and electrical connections from the ends of the fuseblock. An adapter provides mounting the fuseblock on a channel member while using the dovetail joint grooves and ridges. The adapter mounts on the channel member through rotational movement, and the fuseblock mounts on the adapter through translational movement.
