Ok so I'm finishing off some questions for a mock exam and its come up with:
"Explain why an exposed-conductive part MUST be connected to the MET to facilitate ADS?"
But my understanding is that anything that automatically disconnects the supply is connected to the Line(MCB) or the Neutral Bar(RCD), not the main earth terminal, Can someone explain to me how this works and what I'm missing?
am I mistaking the MET for the Earth bar when its something else? I'm not sure
EDIT: I think I have clicked onto it?, Is it that the current would flow through the exposed part and to the MET which would trigger the RCD because it would detect that current wasn't following residually anymore?
