10.04 Ground isolation from the central block using AT&T crossply or LXE cable. This method will provide ground
isolation plus strain relief protection.
a. The cables must enter the case in a butt configuration at the external ground stud end.
Note:
When terminating OFNR cable, ground isolation is not necessary.
b. The crossply members must be twisted or spirally wound. The two LXE members are twisted together
twice.
Note:
The double tape method is required to assure ground isolation from the central clamp.
c. The final crossply and LXE member length should extend 3" (76 mm) beyond the central clamp.
d. Starting 3" (76 mm) from the final cut end, wrap two strips 2" (51 mm) long of 1" (25mm) wide vinyl tape
lengthwise around the crossply members. Make sure the tape is overlapped and no metal is exposed.
Each LXE member requires only one piece of vinyl tape.
e. Wrap a 2" (51 mm) length of #69 glass cloth backed tape over the vinyl tape. Two pieces of tape are
required for crossply cable and one piece for each LXE member.
Note:
The double tape method is required to assure ground isolation from the central clamp.
