Hi all, I haven't done domestics for a while and have been asked to install an 18th edition CCU to a small terraced house ( 2 floors Ground and first). I been told that I need to install a SPD? Can someone confirm this is the case and are there any exceptions. Haven't done my 18th but will be doing so shortly. I found this from crab tree, option 3 appears to give the installer some discretion?



Regards peter

Do you have a copy of the 18th @Cazmac1? There is formula/calculation you can do to determine if it’s required.....but I believe at this time it’s only a recommendation anyway and determined by the cost of things it’s protecting or some such nonsense.......

My boss has just done the 18th and he was adamant that is was required. He has been known to get it wrong on occasion so I wouldn't take his word. It's a PJ so not really his shout. I haven't got the current regs book so can't do the calc, If I can't get an answer I'll probably install one anyway.

Are you aware of the other changes within the 18th edition?
 
Yes all new consumer units must have a SPD installed There is a flow chart in the OSG it is easier just to install one so I have been told.

I would suggest Ashley, that you read 3.7 OSG, Page 38-45, before making a rash statement like the one you have made.
