One comment I heard a while back was something like.....
"I'm using the <10 foot tap rule! The small motor only draws 7 amps, so the 60 amp is still not overloaded"
I bet you got a chuckle out of that.

Greg, I stand corrected.
Another product, maybe a lighting contactor, that I'd come across was listed for 2 conductors per terminal, with the same #14-#8 range.
It had a different torque value given for #8-10 than the #12-14
I got a 30A QO this morning with 30ft pounds given for the torque, no matter what the use (although it says that AL wire may not be used for the 2 wires per terminal application).

I think the different wire size thing on a QO is somewhat limited by use. The wobble plate terminal only goes on breakers up to 30a (hence the 8ga for AL) and you usually are going to be using the appropriate wire for the breaker.
If I saw radical differences in wire side the whole thing would get a second look to see what was going on here.

There's nothing legal with what I'm looking at .. The main problem is the micro arcing that goes on especially if two different wire sizes are sharing a common connection plate .. that would be my take .. besides the lower amperage wires tapped into the heavier breaker is an obvious issue ..
Anyone claiming to know everything about Electrical, is wrong.
