Abstract
A fuseholder assembly includes a two pole fuseholder having load side and line side sections housing a pair of inline fuses which connect respective load and line side terminals, and a breakaway receptacle that releasably joins the line side terminals to corresponding line conductors. The line side section of the fuseholder includes a boss on one side thereof and the load side section and breakaway receptacle each include mating grooves formed therein. The boss is received within both grooves when the fuseholder assembly is properly assembled to polarize the fuseholder sections with respect to one another and to polarize the attachment of the breakaway assembly to the line side fuseholder terminals.
