Abstract
Abstract A wire nut tool which includes a sleeve having an open end and an opposite connecting end, a first cavity in the sleeve proximate the open end sized to receive at least a portion of a wire nut, and a second opening proximate the opposite end of the sleeve sized to receive a second wire nut. Slots are formed in the sidewalls of the sleeve proximate the open end for receiving the turning wings of a first wire nut and second slots are positioned in the sidewalls of the sleeve proximate its connecting end for receiving the turning wings of a second smaller sized wire nut.
