7.4 Twist Cables and Junction Box
The twist cable junction box should be mounted on the inside of a tower leg approximately 3.7 m
(12 feet) above the tower base. This height may need to be adjusted, depending on twist cable
length. The vertical cable droop must be approximately 1.8 m (6 ft) (see Appendix B).
Two Unistrut, split pipe clamps are used to secure the box to the tower leg. The box should be
oriented with its door facing towards the center (inside) of the tower (see Appendix B).
The two twist cables can be connected to the junction box. Conduit should be installed between
the twist cable junction box and the control enclosure. Please note that whenever holes are
drilled through electrical boxes for conduit installation the edges of the holes must be coated to
prevent adverse corrosion. Failure to adequately coat metal may lead to early deterioration of the
enclosure.
