What is it that makes those on the NEC committees more knowledgeable than the best technical people here in this forum?You will never convince him. Don Tom has made that pretty clear.
I could be convinced by some good well proven facts, but not just because somebody says so.
And FWIW, I am already a little convinced when the guy in the video mentioned gas lines--something I never thought about before. But to be 100% convinced, an issue that actually happened would have to be shown, such as a house blowing up all because it has a 3-prong instead of 4-prong drier outlet.
