do i need a new consumer box

[marsaday]

i understand the regs have changed again.

the sparky fitted a new consumer box last sep with one rdc.

we hope to convert our attic and the electrics have been taken up the hall wall to go into the attic ready for this conversion. we will start next yr some time.

do we now need to change the new consumer unit ?

No you don't, technically, thou I would have thought the spark would have thought for longer as the majority knew about entirity RCD protection.

All circuits on one RCD means pitch zero power on tripping, nice in the dark!!!

However are all your circuits on 1 RCD ? or did you end up like me when a spark fitted a CU a few months before 17th edition was to be inforced, and fitted a split load... 5 way non RCD, and 5 way RCD protected. And this is before I understood what 17th edition was.

incidentally, if you had a LABC inspection now, would they pull you up on not having a 17th edition CU ?

Technically, if the system was designed before 1st July 2008 then it can be installed, inspected and tested to the 16th edition of the regulations.
If it hasn't been designed yet then it will need to be done to the 17th, I doubt you'll need a new CU - you'll probably get away with the use RCBOs (depending of course if they make them for your CU).
What make of CU?

They shouldn't, as there's no compulsion to have one.

It's a bit hard to discuss the subject when quite clearly there must be loads of 17th edition regs books out there with page 39 either missing or blank..
