Minimum circuit amps for well

[crtemp]

I am hooking up a well for a customer and it has 12 awg coming out of the well head. I thought for some reason that wells had to be on a 30 amp minimum circuit. Am I wrong?

Yes.

Why do you think this is correct is the question?

You need to know more info.
HP?
Voltage?
Phase?
Cap start from a control box above ground or onboard the pump?
Control via pilot duty or direct?
Gather info and apply Art. 430 requirements. There is no such thing as standard or required amperage.

Yes. The circuit is sized to the motor.

Yes. The circuit is sized to the motor.

Okay, what size is the motor?

You could still have a 30 amp overcurrent protective device on a 12 awg wire

Something I never understood is why the circuit rating was based on the overcurrent protective device and not the wire size as well. (210.3) Certainly the ground fault and short circuit rating is based on the overcurrent protective device but I think the wire would rate the circuit as well.
