Think of like an RCD (actually its more like the old ELCB's) that doesnt trip but gives a warning of problems, its used with IT systems

Think of the scenario of an electro-magnetic carrying scrap cars around a scrap yard; tripping off the power when there is a problem is PROBABLY not the best option......

- Buried cables in safe zones LESS than 50mm from the surface UNLESS earthed metallic protection Provided

must start by sayin am not too familiar with th forum...is there anythin in 17th that mentions the need to use steel conduit when the socket is at the other side of a wall of a classroom say...unless it is within 150mm from corner of a room, cornice or boxed in steel column etc
