There are additional places in the 2023 NEC where 10
Amp circuits and aluminum wire are added, however due
to space limitations in this guide we only cover these.
We think that this is adequate to convey the intent.
Change Summary
• The NEC is introducing text to recognize 10 Amp
circuits with limitations.
Article 210 Branch Circuits Not Over 1000 Volts ac,
1500 Volts dc, Nominal
210.23 Permissible Loads, Multiple-Outlet Branch
Circuits. In no case shall the load exceed the branch-circuit
ampere rating. A branch circuit supplying two or more
outlets or receptacles shall supply only the loads specied
according to its size in accordance with 210.23(A) through
(E) and as summarized in 210.24.
(A) 10-Ampere Branch Circuits. A 10-ampere branch
circuit shall comply with the requirements of 210.23(A)(1)
and (A)(2).
(1) Loads Permitted for 10-Ampere Branch Circuits.
A 10-ampere branch circuit shall be permitted to supply one
or more of the following:
(1) Lighting outlets
(2) Dwelling unit exhaust fans on bathroom or laundry room
lighting circuits
(3) A gas replace unit supplied by an individual branch
circuit
(2) Loads Not Permitted for 10-Ampere Branch Circuits.

210.24 Branch-Circuit Requirements — Summary.
The requirements for circuits that have two or more outlets
or receptacles, other than the receptacle circuits of 210.11(C)
(1), (C)(2), and (C)(3), are summarized in Table 210.24(1)
for copper conductors and Table 210.24(2) for aluminum
and copper-clad aluminum conductors. Table 210.24(1)
and Table 210.24(2) provide only a summary of minimum
requirements. See 210.19, 210.20, and 210.21 for the
specic requirements applying to branch circuits.
