Hi, I found 5 ring final circuits used for sockets, protected by MCB's instead of RCBO'S on a 3p board with no rcd, there are also 20 further circuits used to power hand dryers, under sink water heaters & panel heaters with no rcd protection. The site was only refited <12 mths ago?. Have put qoute in to fit rcbo's to the 5 circuits used for sockets, unsure if the other 20 circuits powering the above need rcbo protection, any ideas/recomendations?
