When the first electrical devices were put into operation on a construction site, the residual current device immediately blew out. I then began to narrow down the current path and ultimately had to dismantle every socket to find the fault - so close and yet so far - it was the last socket in the socket circuit - the neutral conductor was also clamped onto the PE conductor - that was the reason - great thing :-) I expressly point out that work on electrical systems may only be carried out by qualified electricians, as required by law. I accept no liability whatsoever for the technical, legal and safety-related accuracy of the content in this video.
