I recently installed a 30 amp ocpd on a #12 thhn to feed a 2 hp 230 volt 1ph pool pump.
table 430.248 FLA is 12 amps , size of wire at 125 % = 15 amps I used # 12awg then I sized the ocpd -
at 250% x 12 = 30 amp breaker this motror has intregal overload protection.
the inspector told me I cannot have a #12 awg conductor on a 30 amp breaker and I know he is referring to table 240.4 where these sizes are not allowed to be protected over those ratings. i.e. 14awg-15amps, 12awg-20amps, 10awg-30amps.
However I thought the motor rules allowed this to be praticed?
