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.
