Commercial -MCBs/ Rcbo's?where to use?

by Sparkydelux » Wed Apr 15, 2009 9:16 pm

Hi All,

I am doing a school installation (commercial). 3 Phase and on ground level only.

My question is: Do I need to have all circuits as RCBO's or can I use MCB's?

The cost of RCBO's are pretty hectic when you are supplying 26-30 of them.

I know there has to be RCD protection on most boards to comply with 17th Edition so I am just curious to see where I can and can't use MCB's.

Also if its RCBO's I'll be there testing forever!!!

Your wisdom is always appreciated.

Regards,
