is it possible to flow a current between nutral and earth
in a circuit? although nutral and earth having same
potential diffrence?
i=0/r=0A
if any body now any solid reason because i am getting a
triping problem in rcbo due to nutral and earth shorting???

Answer Posted / k.prakashchandra

If there is a loose connection in the neutral wire ,neutral
point gets shifted to the point of loose connection at the
incoming.Then there will be some voltage in the neutral wire
beyond it, resulting in flow of current when in contact with
the earth wire.

need to make a report. Need to choose a 3phase induction motor. Load conditions motor will operate in : Maximum Load: 30 Kw Speed: 2950 rpm Ambient temp: 20 cent Supply voltage: 440V Frequency: 50Hz need to look for the safety factor when choosing the motor, went through catalouge found a few, but dont know how to choose the safety factor allowing an extra load something above 30 KW to avoid any harm.

if an insulated power and control cables of a running gas diesel gensets laid direct in an open trench i.e, trench bed is not rcc of a power house in which rain water, spillage water alwas exists and all power control cables remains submerged even when gas gensets of 480 kw each runningin on load. These power &control cables runs from power house to switchgear room through these trenches in which water remains most of the time. pl explain its merit & de-merit
