240.4(D) references 240.4(G) which allows you to use 310.16 ampacities keeping 110.14 in mind. If your terminations allow 75?, then you may use that column for Art 430 applications.
(the #10 would be allowed)
(the #10 would be allowed)
If my wires are installed underground in conduit I believe I need to use the 75deg C column?
430.22(A) leeds to 430.6(A)(1) also look at the tables that start at 430.247.
Remember your FLA is 35 amps look at 310.16 table #10 75deg =35 amps if you use #10 you would be loading it at 100% remeber the 80% rule that i can not find right now:grin: so i would go with # 8

You need to use the 75deg column based on the temp rating of the wire's insulation and equipment you are hooking up.

The load is actually 27 amps not 35 amps so with #10 conductor's he's really at 80%.
