Abstract

A slip-fit electrical connector compatible with different size threaded transformer studs includes a body having a plurality of transverse conductor receiving passageways, and intersecting conductor fastener receiving passageways. The body also has a multi-size transformer stud receiving passageway extending longitudinally inwardly from an end thereof, and at least one stud fastener receiving passageway intersecting the multi-size transformer stud receiving passageway. The multi-size transformer stud receiving passageway may be defined by an arcuate bottom, and a plurality of successively larger threaded stud landings with a lowermost threaded stud landing being bifurcated by the arcuate bottom. Each successive threaded stud landing may be bifurcated by a prior threaded stud landing. The threaded stud landings are for different size threaded transformer studs to conveniently and reliably fasten the transformer stud and connector together.
