It is RCCB and not ELCB . You are creating imbalance by
removing one wire

Answer / rajesh verma

Dear
if we take phase from one RCCB and Netural fromsecongd then
it will get tripped because of phase unblance. ELCB will
not get tripped while taking phase & netural from different
source ELCB

Answer / jessie

1st: check the ELCB Current capacity maybe overloaded if you connect your additional load. used ohm's Law formula I= P/E
2nd. check the continuity of Earthing Connection to your additional load.

When testing an earthing connection, we use a 60 or 100 candle bulb with a phase connected direct from supply and the other wire to the new earthing provided.If the bulb glows then the earth is ok.Else earth connection is not Ok. So, why dont we can use all the home appliances taking a single wire from the phase and the return connection to Earth instead of return connection to neutral?
