Problem:
For library ā€œ Directly Buried Cable ā€“ Detail 8 or Detail 7 ā€œ . These should be triplexed cables, Iā€™m not sure why they show up as not being in a triplex form but rather just side by side?

Solution:
Per R&D,
We use equilateral configuration and it is a little more conservative and is on the safety side.
