Does anyone know of a requirement prior to the 2002 NEC 408.21 that requires only one neutral per terminal connection (hole)
NEUTRAL CONNECTION ONE PER HOLE

It was part of the UL listing of the panelboards long before 2002. They only added wording into the NEC because no really knew about it.

Yah, like me. When I broke into the trade I was taught to double up on the neutral. Nobody was trying to be a bad guy or a rebel we just didn't know any better.

Way back when cable with ground wire was first introduced we always put the ground and neutral in the same hole.

I don’t remember when we quit doing it. Not sure if why either.

I still find this all the time. To be honest, it makes tracing wiring in a panel a lot easier.

One in the front hole, one in the back hole...

I'm guessing. Some of the older panels and square D QO had tiered terminals.

Probably on another thread, but they referred to a double-row of neutral bars-- one in front that was getting used, the one in back ignored. Making it more fun to add another connection.
I was referring to the comment about the neutral and ground in the same hole-- but using the 2 rows of neutral bars would maintain the 1-wire-per-hole, but keep the neutral and ground close together. Not complying with code...

I cringe when we need to work on the old narrow box GEs. They were the worst.

And they were always filled with 1/2 size breakers as well, so you get 20 single pole circuits in a box about the size of today's 6/8 circuit QO panels.
