Here there is no one to define said line but me. If i don't like it, i don't energize it. I am the one who ultimatley is liable ( yeah, all other 'subs' will point to me..)

As such, i have 'got into it' with a number of excavators, who assume ( key word) that i will 'make work' whatever configuration they leave me. I have had to stand my ground,and have lost biz to this. A common line i use in said confrontations is that i won't dig , if you don't wire. 'Wire' includes anything that a conductor passes thru....

Case in point, i require a pedestal by a residential sewer pump .
Excavators run a 3/4" pvc straight into the tank.....
I won't do ( or stand behind) direct burial SEC's, as some excavators will do and expect me ( as well as the poco) to make good on.
I will not stand behind any direct buried conductor short of a GEC.........

Excavators and I have a fairly shaky relationship.......
