I ran 100 feet of 12 gauge wire from my electrical box panels to where I'm about to install a sliding gate motor to open my 16 feet, 200lbs aluminum gate. The motor requires a 10Amp circuit and its 1.5 horsepower. The motor could handle up to 1400lbs, 50 foot gate.
My question is if my 12 gauge wiring will be able to handle such a motor or should I buy a smaller 0.5 horsepower motor instead? I have a 20 amp breaker on this line.
