14 ga. COPPER is only rated for 15 amp circuit breakers.
1 HP = 746 W. P = IV. 746 W/120 V = 6.x A, which is not excessive for a 14 AWG/15 A circuit. (15 A circuits are typically rated for 15 A peak and 12 A continuous load.)
But, I don't know what the actual current draw, peak or steady state, of a nominal 1 HP motor would be. Perhaps peak would be a lot higher.
