size conductors for 100 amp or less load

[infinity]

What I meant is what are terminals considered in a panel? The main lugs, the breakers????

Both.

Both.

So a panel with have the terminal temperature ratings for both the mains and the branch?

Definitely the mains, if it's main lug.

Ungrounded branch conductors would land on the breakers and be determined by the breaker lug ratings. But neutral conductors would land on the panel neutral bar and be determined by the neutral bar temp rating. I suppose the label could be justified for the neutral bar they provided. Very unusual though.

Don's post seemed to indicate the opposite which kind of confused me.

It is my opinion, that the 60°C ampacity limit in the picture that was posted only applies to conductors that are connected to a circuit breaker terminal.

I can definitely see the ratings applying to the connections that are part of the panel but do the panels limits also apply to the third party circuit breakers?

I should have clarified sorry. I know exactly what terminals are. What I meant is what are terminals considered in a panel? The main lugs, the breakers????

Like, I said, a terminal is any thing that you connect a wire to any where in the equipment.

I stand by my statement that the note calling for a 60°C ampacity on that equipment only applies to conductors connected to circuit breakers. There will be ratings for the other terminations, but I do not see that note as applying to other terminations.

How would it not apply to the neutral bar terminations?

Where else would other termination ratings be labeled?

It might, but there would be no reason for it to apply to anything other than the breaker terminals and that is how I would read it.

I read it the exact opposite. The neutral conductors are those which land on the equipment with the label. They are no less branch circuit conductors than those that land on the breakers, but the breakers have their own labels and that would determine the ratings that would apply to those terminations.
