HI
Doing a test with a voltage detector/continuity tester on live PME/TN-C-S system installation at a socket outlet either with load and without the load shows voltage between live and neutral and live and earth but live-earth seems to be short circuited and the continuity tester indicates continuity which for me means thet they are short circuited (and I recon they are short circuited ot the orgin as the system gets only one PEN conductorfrom the supplyer which acts as a neutral and CPC at the same time) but the probelem is that even if I switch off the MCB which seems to be very old type like from 20-30 years ago nothinch changes and the continuity between earth and neutral still exist. my question is if it is cused becouse the mcb may not be a double pole switch? if it safe (all appliances connected to the sockets work propelly but the question is if they are safe)? what test should i do on top of what i have dont to make sure all of above?
many thanks
