IEC Metric Motor Requirements 1

[dbarnard]

I am assisting a colleague on a project and need a little help on a question we have.

We are designing a product that utilizes a standard IEC induction motor and are adding some components such as a thermal overload and switch to the terminal box. In order to do this we must remove the existing terminal block that comes standard on this IEC motor.

Is there a standard that requires the use of terminal blocks on IEC motors? Every IEC motor i have seen has the terminal block setup.

I should include, it is a 115-230 single phase motor.

Thanks everyone.

Why pray tell are you adding a thermal overload to the motor connection box? Bad idea IMHO.

I should have said switch\circuit breaker not thermal overload, sorry.

Check NEC Article 430 if the motor is larger than 1/3 HP.
