PSA: Grounding debate got heated on my last service call...

We were replacing an old panel and my partner insisted on doubling up the ground wires... I read the new NEC section and it says not to do that anymore. He says it's always been safe his way, but I worry about inspection. Which side would you take in this spot?

Which NEC edition are you looking at for that "no doubling up" rule?

Wait, is everyone just checking the conductor fill tables and ignoring the whole tap rule thing? I see guys mix that up all the time where they think you can't double up grounds or neutrals in certain boxes, but that's not actually a blanket rule in any recent NEC. It's more about the specific situation, like with equipment grounding conductors in some metal boxes. The code gets read wrong because people hear something once and just repeat it without looking up the actual section.
