Ryan I wanted to thank you for all the content you put out. I worked hard and passed my master electrician exam yesterday. Just a dumb HVAC guy who is now a master electrician thanks again!!
10A permitted per 240.4(D)(3) using 16 AWG CU and per 240.4(D)4) using 14 AWG CCA. At least Eaton and Siemens already have listed 10 A circuit breakers, and those use components in-common with 15A CBs with GFCI and with CAFCI, so listing and production of CAFCI and of GFCI 10A CBs are not that much of a jump. “If you build it, he will come.”
I told an inspector that the whole lighting load of a house could go on 1 circuit if you did the calculation he told me I could only count 8 leds as 1 circuit and he counted 2 switches and 8 leds as 10
3:50 actually, unless we can afford to rewire our house with 12 gauge wiring, there are some receptacles at the end of a branch circuit with like 14% voltage drop. I have actually looked into getting 10A breakers for that circuit to derate it for safety.
Nice discussion Ryan. Especially your magic eight ball readings from someone familiar with the actual pace of the Code changer. I'd love to be able to string 16AWG Romex lighting circuits because it makes obvious economic sense. A few months ago when I saw 10A were allowed in 2023 I immediately checked the table for the new wire size; immediately did a double take that they still required 14AWG copper; and thought to myself why did they bother? But your speculation makes sense. First they bless the new smaller branch circuit size (even though no-one will bother using it), and then try to work in the new wire size over the years.

Your understanding of the realities in our field is truly a blessing! Thank you as always 🙏

Copper prices are going to continue to rise- at some point 10A wire will be on the market.
