210.23(A)(1) - 2023

[xformer]

Hello,
In looking at the 2023 code, I do not see ceiling fans as being allowed on a 10 amp Branch circuit. Is that a correct assumption?

I would say that you are correct. It specifies the equipment that is permitted on these circuits and #'s 2 and 3 specify what circuits. See "Charlie's Rule" in this forum. I don't even know if they are making 10 amp breakers for panelboards. They might be though. I just haven't seen them.

When they proposed 10A circuits I figured they would allow 14 AWG copper clad AL.
If I read 334.104 and 310.3 right it still has the smallest copper clad AL at 12 AWG.
I thought perhaps a new 16 AWG stranded copper 'joist pull' type of tray cable but nada.

I think the only effect a 10A circuit has on us is with small fractional HP motors in article 430.
Or a 10A breaker with #14 could be used to comply with voltage drop requirements in other codes.

They have been making 10 amp breakers for panels for decades. They were not a standard size prior to the 2023 code. One of the issues will be dwelling units and the AFCI requirements as I don't think there are any 10 amp AFCIs.

Also 3 phase bolt on breakers. Say I have a standard 3 phase 480V 3HP motor and a 10A breaker is sufficient to start it.
I think by the letter of 430.52 I'd need a 10A breaker.

Yes, anytime the motor full load current from the NEC tables times 250% is less than 10 amps, you will need to use a 10 amp breaker under the 2023 code as that size is now shown in Table 240.6. The same motor, under the 2020 code, could have used a 15 amp breaker.

Could use a fused disconnect with 10amp fuses

If you are using fuses as the motor protection you have been required to use fuses smaller than 15 amps for a long time as 240.6 says, in the 2020 and earlier codes that fuses rated, 1, 3, 6, 10, and 601 amps are standard sizes.
