In regard to threaded grounding bushings (with grounding lug on it), where are these to be installed?
I was checking 250.97 and 300.4(G) in the code.
If possible, could you refer me to the code sections, where we must install such bushings, as compared to normal bushings?
Just trying to have code references, so we don't install ground bushings where they are not needed.
Thanks - Good day
