IR test bellow 1Meg

MrJack96
Is it dangerous a low reading such as 1Kohm for IR I know you need to seriously investigate but if a 3 phase submersible pump is installed correctly wouldn’t the breakers/ fuses blow before the equipment is unsafe. 


230/1000 =0.23ma?

    The measurements were at the motor.


    So were you measuring the IR of the motor, the IR of the fixed wiring, or both in parallel?
