DETAIL 1

1. THIS METHOD OF CABLE SHIELD GROUNDING APPLIES TO EXISTNG CABLE INSTALLATIONS WHERE GROUNDING IS REQUIRED AND CABLE REPLACEMENT IS NOT OTHERWISE AUTHORIZED.

2. ATTACH UPPER NUT APPROXIMATELY 12 INCHES ABOVE THE STUFFING OR SWAGE TUBE.

ATTACH GROUNDING RINGS AND SPACER BELOW THE UPPER NUT AS SHOWN IN THE FIGURE. ATTACH LOWER NUT BELOW THE LOWER GROUNDING RING. TIGHTEN UPPER NUT ONTO LOWER NUT UNTIL THEY ARE THREADED LIGHTLY TOGETHER SO ADAPTER WILL MOVE FREELY ON THE CABLE.

3. PACK STUFFING TUBE AS REQUIRED, COAT THREADS OF LOWER NUT WITH ANTISEIZE COMPOUND OF A-A-59313. THEN LOWER THE ADAPTER AND THREAD INTO STUFFING TUBE, TIGHTENING LOWER NUT AS REQUIRED FOR PACKING. UNSCREW UPPER NUT FROM LOWER NUT AND MOVE UPPER NUT AND THREE INNER COMPONENTS SEVERAL INCHES UP

THE CABLE AND TAPE. MAKE CUT IN THE CABLE JACKET AT A LOCATION WHICH WILL ENSURE THAT THE GROUND RINGS MAKE CONTACT WITH THE EXPOSED SHEILD WHEN THE LOWER AND UPPER NUTS ARE TIGHTENED.

4. REMOVE CUT SECTION OF CABLE JACKET AND APPLY A COATING OF ANTISEIZE COMPOUND OF A-A-59313 TO THE EXPOSED CABLE SHIELD AND TO THE THREADS OF THE UPPER NUT. LOWER THE UPPER NUT AND HAND TIGHTEN FIRMLY, MAKING SURE THE GROUND RINGS FALL INTO THE SLOT CUT IN THE CABLE JACKET.

5. THIS TYPE OF INSTALLATION DOES NOT REQUIRE PERIODIC TIGHTENING OF THE GLAND NUT (GROUNDING ADAPTER) FOR WEATHER SEALING.

6. THE THREADS OF THE LOWER NUT SHALL BE CHOSEN TO MATE WITH STUFFING TUBES, METALLIC CONNECTOR BACKSHELLS, PANELS OR METAL BOXES DEPENDING ON THE SPECIFIC APPLICATION.
