Why sockets cause friction
A socket looks trivial, but undefined responsibility turns a small item into a standing argument. Clear the gray area before the install, not after the first fault forces an awkward conversation, because by then both sides have already formed opposing stories.
The sound view
Settle the fuzzy boundary early. Prepare the needed materials and documents up front so the work is not paused by missing basics later when the crew is already on site and billing, because a delay at that point costs far more than an hour of planning.
Materials to prepare
Site drawings, load figures, and the named contact for faults.
