Is the amp value on 310.16 based on RMS or peak values?

Rather embarrassed to not know the answer but I saw something on a reel that made we question something I thought I knew.
The value given on our clamp meter is RMS much like voltage is RMS. I think I assumed it was peak amps.
But is the values on table 310.16 RMS or peak amps? Couldn’t find language regarding that on the table but I hope it is based on rms amps.

Everything in the NEC regarding AC is RMS.

They are based on RMS amps.

The rational is that the current limits are set by resistive heating of the conductors, and RMS current is the number that gives the same resistive heating for different waveforms.

Thanks. That makes a ton of sense.

I assume your question is from the video in the link?
