Answer Posted / abdul nazir
Earth pin diameter is bigger than phase & neutral, because
conductor area increases its resistance will be reduce, so
fault current will easily flow through this path, this is
the reason why earth pin is bigger than other two pins.
compare to other two pins, the earth pin LENGTH also more,
because every electrical equipment should earth first.
(safety reason).
And also we cant insert(by mistake) the earth pin to phase
hole(plug).

Can u explain : what is supply for train (whether a,c or d.c ).I know that supply is 25000v a.c .But there is rumour that supply is D.C. And also explain how lights and fans inside the trains are working ,and what type of motors are used in trains whether D.C motors or induction motors .If d.c motor, how it gets supply.If traction motors are used then what are traction motors and its functions and how it differs from other motors and also explain about locomotive . y d.c series motor in train.train wheels r driven by D.C shunt motor ,at what voltage,and at what speed. please reply..............
