I'm doing some DIY wiring and most of my experience has been working on my own house. When collecting the bare grounds in an outlet/fixture box, I add a pigtail to attach to the grounding screw, twist them tightly with lineman's pliars, clip them cleanly at the end and twist on a wire nut nice and tight.
My current job needs to be permitted, and I hear from local pro electricians that the inspectors in the area are expecting to see these bare grounds twisted and crimped with sleeves.
Attached is a picture of my stripping/crimping pliers. Will these pliers do an adequate job of crimping? I've heard of crimping pliers that make an even crimp all around the sleeve, but understand these crimpers may cost $50.
I did not see any special crimping pliers at HD or Lowe's. do I need special crimping pliers or will my present pliers work satisfactorily?
