An electrical connector for configuring the supply voltage of rotary electric machines, particularly electric motors, having a plurality of electrical windings. The connector includes an electrical terminal block mountable in a bell housing of the rotary electric machine. The terminal block includes a socket having a plurality of female electrical connectors coupled to a corresponding plurality electrical windings. A male electrical connector having a plurality of jumper pins matably engageable with the female electrical connectors of the socket in a first and second configurations to electrically configure first and second winding portions of each electrical winding in parallel or in series. The connector also includes a visual electrical configuration indicator to indicate whether the male electrical connector and socket are in the first or second configurations.

A grommet and adjustable strap fastener assembly including an elongate strap member having a head portion at a first end in combination with at least one body member having a first strap aperture for receiving the elongate strap member. A retention member protruding into the first strap aperture of the body member permits adjustable passage of the elongate strap member through the first strap aperture in a first direction. The retention member prevents passage of the elongate strap member through the first strap aperture in a second direction opposite the first direction. According to another aspect of the invention, the body member includes a second strap aperture disposed in a recess wherein the head portion of the elongate strap member is disposable in the recess of the body member when the elongate strap member is disposed through the second strap aperture. In one application, one or more fastener assemblies retain a tubular core member between first and second spool flanges each disposed on opposing sides of the tubular core member to form a spool assembly usable for packaging coiled materials including coiled copper tubing.
