APPENDIX D. Cable Replacement Procedure
NOTE
Observe carefully the direction of the wire’s twist. Proper installation
requires this same twist direction right up to the screw terminals. When
viewed from the end, most wire twists clockwise as it approaches the
wire’s end.
3. Arrange the cable and wire pairs as shown in Figure D-2. Do not
untwist the pairs any more than required to strip the wire ends.
4
Cut the two inner wire pairs (orange and blue for EIA/TIA T568B)
to 1
1
⁄
8
inches (28 mm) from the jacket.
5. If using ScTP, cut the bare drain wire to 1 inch (25 mm).
6. Remove insulation
1
⁄
4
inch (6 mm) from the end of each wire and twist
to capture all strands. Optionally, tin the ends to capture all strands.
7. Re-twist each wire pair in their original direction. Use two or three full
twists for the two outer pairs and one or two twists for the two inner
parts.
