A practical question for the electricians here - Is it allowed to use a 5/8” clamp on a 1/2” copper clad rod with a slight mushroom head? Obviously I don’t want it to loosen over time. Some retailers show “G5” types as separate models for 1/2” and for 5/8“, but then some show the very same 5/8” part number as applicable to both diameters. Looking at some spec sheets from the manufacturers, I seem to see similar confusion. The “universal” acorn clamps are clearly for 1/2 through 3/4” diameter rods and their shape is obviously made for that purpose, but they are larger and cost more of course. Then there are rebar clamps which are larger for the same nominal size and would go over the mushroom, but I’m not sure if they are compatible with copper rod. Confusing.
