We were told that the CAT 5 cable (network communications) and the 18-2 signal wire (power limited, switch leg of 24vdc 100milliamp) that runs underground had to be not only in conduit (we are using non metalic conduit to the correct depth) but also it has to be direct burial as well!
Fo rhte life of me I cannot find anything in the NEC either in 830 ot 725 or 300.5.
Is this correct? when would I ever have to use both?
