Panelboard circuit numbering

[ElectricFarmer43]

Good Afternoon, I had an unique question brought to me recently that I did not know the answer to. Are circuit numbers required to be labeled next to each circuit breaker per NEC requirements? I am talking about a number label next to each circuit breaker e.i....1,3,5,7,9 down the left side and 2,4,6,8,10 down the right side ? I understand NEC article 408.4(a) which requires a written panel directory but I am not sure if this applies to the circuit numbering as well. I recently had a general contractor ask me about this and required it on his jobsite. I remember when ITE/Siemens used to give you the little plastic numbers that I used to have to twist out and pop in the tiny square hole on the panelboard cover. I did not know if this was a NEC requirement or NEMA requirement? Thanks in advance!

I think that the words "The identification shall include an approved degree of detail that allows each circuit to be distinguished from all others" would require some sort of marking at each breaker that coordinate with the directory so that is can be distinguished from the others.

Some panels come with numbers. I like to put them on the breaker so the number can be seen with the trim removed. My panel schedules went in a plastic holder, I would put the schedule at eye level when making up panel.

Most panels now days have numbers stamped in the metal on the deadfront. Just match the numbers to the description in the directory or schedule.

I would think you could have your own numbering system. as long as the circuits can be identified by labeling.

I always thought it would be better if the right half of I line panels where numbered from the bottom up
