Limit on Tandems?

Hi all, Came across this box the other day with a lot of tandems, I thought they were supposed to be limited in number? It’s a Cutler Hammer panel.


The label inside will tell you if tandems are allowed and if so how many. You can also figure it out from the model number of the panel most times.

It is a CTL panel #5340, unfortunately the panel legend was faded and illegible.

Minis are not allowed in Chicago for anyone in my area.
