(i) The other end of the power cable extended
along the mast is connected to the secondary lead of a
stepdown transformer placed at the bottom of the mast.
Two single conductor power cables are connected to the
2 primary leads of the stepdown transformer (figure 45).
These cables are then connected to the primary leads of
other obstacle light transformers or to the inner threshold
light transformers. If burial is required, obstacle light
transformers and connecting cables are buried at least
18 inches (45.72 cm) deep, with the transformer
secondary lead exposed.
