phase & 1 neutral ) to cater our electrical load .
the issue is though we have Glanded the cable both the end
also givan the earthing to the panel both the end we are
facing a heavy sparking at the gland side. what could be
the reason.
Answer Posted / k sharma
It could be any nearby electrical machine not being
properly earthed and it is taking earth from this gland
leading to heavy sparking.For eg there could be a welding
machine nearby and the work may not be properly earthed.
