Abstract
A method for creating an electrical earth contact to electrically couple a contact shoe to an electrical contact stud using a polymeric material cap nut includes creating an external thread on a shank of the stud. A contact flange is fixed to the stud such that the contact flange faces the shank. The cap nut is selected from a non-conductive polymeric material and from a plurality of sizes of cap nuts. The cap nut is threaded onto the shank until the cap nut engages the contact flange. A torque is applied to the cap nut, the torque selected from a torque range operating to prevent pullout of the shank to electrically engage the contact shoe between the cap nut and the flange.

A method for creating an electrical earth contact to electrically couple a contact shoe to an electrical contact stud using a polymeric material cap nut, the method comprising:
- creating an external thread on a shank of the stud;
- fixing a contact flange to the stud such that the contact flange faces the shank;
- selecting the cap nut from a non-conductive polymeric material and from a plurality of sizes of cap nuts;
- threading the cap nut onto the shank until the cap nut engages the contact flange;
- and
- applying to the cap nut a torque selected from a torque range operating to prevent pullout of the shank to electrically engage the contact shoe between the cap nut and the flange,
- wherein the plurality of sizes of cap nuts includes a 6 mm diameter;
- and
- wherein the torque comprises a range between 8 to 10 Nm inclusive applied to the cap nut for the 6 mm diameter.
