Can you elaborate on this? I'm not clear on what you're saying.
What I'm saying is that on a typical underground service here in MA excavator digs trench and sands the bottom to protect from rocks. Then we install underground raceway (usually pvc for residential), install service, and pull underground. Excavator then lays about a foot of sand on top of pipe, and we lay caution tape. Then we get our trench inspection, along with service inspection. (Some guys just lay conduit and pull wire and get trench inspection and do service later) Then after inspection, excavator completes backfilling of trench.
My point, and after reading it I realize that I wasn't clear, is that this inspector wants to see the conduit before wires are pulled so that he can decide if holes or notches will be required in the conduit in order for water to drain (if he feels water will enter conduit from transformer base or handhole). He said that if wires are already pulled, then drilling the holes could damage the wires.
We have a few towns which require trench inspection prior to wires being pulled. They cite 300.18 That's ok. I was just relaying his reasoning on inspecting trench prior to pulling conductors. Not because of 300.18, but as stated above.
Thanks,
