Question:

What is the maximum continuous load that can be connected on a 240 volts 30 amperes circuit using two 10 AWG conductors?

A
24 amperes

Explaination

Refer : NEC 210.20(A)

Circuit conductors should be rated at 125% connected load which is continuous.

Refer NEC Table 310.15(B)(16)

8 AWG conductors maximum ampacity is 30 amperes

The maximum continuous connected load = 30 / 125% = 24 amperes
