MCCB IS A PROTECTING DEVICE THAT PROTECTS CIRCUIT FROM OVER
LOAD AND SHORT CIRCUIT IT COMES WITH CURRENT SETTING THE
SAME FUNCTION IS OF MCB BUT THERE IS NO SETTING

RCCB USED FOR PROTECTION OF PROPERTY AND PERSON IT DETECTS
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
