LEAKAGE CURRENT AND BREAKS CIRCUIT

RATED CURRENT IS THE CURRENT FOR WHICH EQUIPMENT CAN
CARRYSAFELY WHITHOUT HEATING OF ITS PART ABOVE ALLOWABLE
TEMPERATURE

THERE SHOULD BE SUUFICIENT RESIDUEL MAGNETISM IN POLE OF
MOTOR TO SHOW VOLTAGE IN CASE OF DC MOTOR , OFCOURSE IT CAN
RUN AS GENERATOR

IN AC MOTOR NA BHAI NA
