Is an overload device required for a 1/2HP, 120vac pump?

I am providing a control panel and typically always include an overload device no matter what size motor load. Does the code require an overload device for a small pump?

Thanks is advance your response.
 
Yes, all motors need overload protection but there are a few ways to provide it. Check out Part III of Artcile 430.
 
Thanks for the quick response...

MY control panel will have a disconnect switch and the correct size fusing for the pump but I'm not so sure the NEC requires a overload device as well.

Any chance you could clarify this for me

If your motor is automatically started or not, the info below would apply.

(B) One Horsepower or Less, Automatically Started Any motor of 1 hp or less that is started automatically shall be protected against overload by one of the following means.
(1) Separate Overload Device By a separate overload device following the requirements of 430.32(A)(1).
For a multispeed motor, each winding connection shall be considered separately. Modification of this value shall be permitted as provided in 430.32(C).
(2) Thermal Protector A thermal protector integral with the motor, approved for use with the motor that it protects on the basis that it will prevent dangerous overheating of the motor due to overload and failure to start. Where the motor current-interrupting device is separate from the motor and its control circuit is operated by a protective device integral with the motor, it shall be arranged so that the opening of the control circuit results in interruption of current to the motor.
 
I agree, but the OP should say what the motor is driving.If it's running a conveyour or anything else that could cause injury, the T.O.L. should be manually reset.
