How to Install Underground Cable Stress Cones

Turn off the power at the source and confirm it is off by touching a non-contact voltage detector to the wire's insulation. Double-check it is off by trying to activate the device to which it is attached.

Check that the cable size works with the stress cone kit by looking in its owner's manual for the kit range.

Determine the amount of bare wire you need exposed at the end to connect to the device or terminal. This information is located in the owner's guide for the connected device. Add this length to 229 mm; the result is the total length of cable jacket you need to remove.

Measure from the end of the cable back the length of cable jacket you calculated for removal. Remove the cable jacket from this area.

Measure forward from the start of the cable jacket 38 mm and remove the tape shield from here to the end of the wire.

Measure forward from the end of the tape shield 38 mm and remove the semi-con from this location to the end of the wire.

Measure forward from the end of the semi-con back 229 mm and remove the insulation from this location to the end of the wire.

Remove the white release liner from the back of one of the mastic strips in the installation kit. Wrap the mastic strip around the cable jacket 6 mm from its end.

Align the pre-formed ground braid along the cable so that is is perpendicular to the cable shield and centered on its end. The solder block on the ground braid should be directly over the mastic strip. Secure to the cable shield with two wraps of Vinyl tape upstream of the mastic strip.

Bend the ground braid at 45 degrees where it meets the tape shield and wrap it around the tape shield. Wrap a constant force spring around the ground braid to secure it to the tape shield. Wrap a second mastic strip over the first mastic strip on the cable jacket.

Wrap the mastic seal,, constant force spring and exposed tape shield with two overlapped layers of vinyl tape.

Push the lug onto the end of the bare wire and secure with a lug crimping tool. Wipe the cable insulation with a solvent saturated pad from the installation kit.

Slide the termination body over the cable and remove its core at the same time. This is done by pushing the termination body on while pulling and uncoiling counterclockwise the prolypropylene core.

Connect the ground braid to the electrical system's ground following local electrical codes.
