2052i have 400/230v transformer and didnt done the neutral eatrhing. i connected one lamp to one phase and neutral to the earth. but the lamp is not glowing. again i connected neutral to earth and repeated the same. then the lamp is glowing. in the first condition i tested with a line tester also, at that time the tesrer is glowing what is happening i dont know can any one help me?

why do motors burn out? I understand why adding parallel loads to a power source means more current moves through the circuit, and can destroy circuit elements by overheating.
