rules for Breaker position in box
hi,
i noticed on my breaker box, the printed sheet on the inside of the door says that the last breaker slot can only be used for a >50 breaker or something, but on another panel that i'm working with it mentions nothing of this.
i'm going to add in a 100A breaker in this box and run it to a subpanel, does the placement of the breaker matter? should it be closer to the main 100A breaker?

I have never seen any limits mentioned like you describe. I bet it's an old panel?
It does not matter where you put a breaker. I have heard arguments both ways but the bottom line is there are no restrictions as to breaker placement.

That said, I am no expert. I suspect the only authoritative answer will come from the manufacturer, which has presumably submitted the unit for NEMA, UL and CSA testing under the conditions listed on the label. You can do as you wish and assume the risk, or check with the mfgr. and figure out your options if they say "don't do it."
To avoid all this, consider moving a couple of higher-level breakers further down. Wire nuts should be OK if the branch conductors are not long enough.

Max, what type of panel is it?
Maybe it's an odd brand and anything larger than a 50 will not physically fit.
If it does say this there is probably a reason.
My comments were directed at a typical panel without any labeling restrictions.
