PigTails and
PowerTails<sup>®</sup>The Ring Terminal used is a true grounding ring that actually "bites" into the screw head and receptacle box to insure an excellent "ground" connection.

    The factory made insulation crimp on the Ring Terminal and Flanged Fork Spade Terminal puts less stress on the conductor’s strands to ensure an excellent ground and power connection because the strands will not break or separate when these conductors are is pushed into the junction box.
  • The Flanged Fork Spade Terminal has "angled" flanges on the end of the "fork" that will stay in place to help the installer connect the PigTail or PowerTail to the appropriate screw on the receptacle, switch or device.

Ground Clip
EPCO’s Ground
ClipEPCO’s Ground Clip are specifically designed for termination of the grounding conductor and should be used when a 10-32 grounding hole is not pre-drilled or tapped into a metallic junction box.

The correct way to install a ground clip is to feed the grounding conductor into the ground clip with the shorter part of the ground clip placed inside the junction box. Then use the flat blade of a screwdriver to force the ground clip onto the junction box to ensure a good electrical connection. See photo.

Since ground clips are forced onto the junction box, EPCO recommends using a "new" ground clip instead of re-using the old ground clip. Ground clips should never be forced onto the round portion of a plaster ring or a poor electrical connection will result.
