The way I read Bigjohn's post it can only be used direct buried as service entrance cable.
Forgive me for sounding ignorant because I'm green as can be and I have a bunch to learn.
I don't know specifically about Cerrowire, but according to 338.10(B)(4)(b), it says type USE has to comply with Part II of 340, the section covering UF. Looking at II of 340, 340.10(1) lists it as acceptable for direct burial, following the requirements of 300.5.
So, judging from those sections, as a general statement, not valid in all instances, type USE is valid for direct burial. Am I on the right track here?
