elecbob,

You are not required to run 10 AWG for this motor. Table 430.148 lists this 1 HP motor at 16 amps add the 25% for motor loads [430.22(A)] and you get a 20 amp load, 14 AWG at 60C is rated 20 amps [310.16] and you will still be able to put this 14 AWG on a 30 amp breaker [430.52].

Because this is a motor load the normal rule of 240.4(D) (15 amp breaker for 14 AWG) does not apply, look at Table 240.4(G)

Do you have motor overload protection as per section III of article 430?

Bob
