in three pin pluge there three pins one is phase and second
is earth third is nutral why nutral high diameter compare
with phase and earth

Answer Posted / vinod bhardwaj

nutral pin always more dia compare than the phase & earth
pin
beacuse current always follows the low resistance path
beacuse of more dia it have large area compare than other
pins .if area is more lesser will be the resistance
beacuse resistivity =resistance*length/area

in case of any short ckt current always current rise
abruptly hence low resistance path provide the easy & fast
flow to current
