RCD's for PC's in commercial building

[bigdavs83]

Think these guys are chancers! Any ones we do are only for wall sockets or cleaners sockets. If you install an rcbo on a line of pcs with monitors and the like then you've got a full time job resetting them. Also you wouldn't be sticking an underfloor busbar on a rcbo. What's the difference there? The floor boxes are completely the same with the same use. I clamped one of our buildings main earths just out of curiosity and it was leaking 10amps!! Apparently all quite acceptable.

I have 5 computer classrooms all on rcd protection; 10 pc per circuit and up to press no nuisance tripping but of course not using standard 30mA rcbo's then id be asking for trouble....

The new amendments of the reg due out in the distant future will require a trained and skilled person to be knowledgeable in Electrics so you can't just appoint any tom dick or harry like you can now so regardless of what you can get away with at the moment the omitting or rcd protection is going to get a lot harder.

Biff although the reg's allow a way out a lot of local authorities demand RCD use within the schools and colleges ... the trick is to have up front good design possibly with use of Schneider SI trip units ...this issue is when you adapt the old to meet the new ...that cost start to ramp up.

They used to insist on Isolation transformer systems in school classroom labs and the like, (can't think of the name at present), but that seems to be something else that's been lost!!!
