Would I get away with this?

Right, here comes the story...

Me mum had an extension on her house few years ago, which I completed all the electrics for when i was an apprentice, many moons ago and pre 17th edition. As I was living there at the time and as you do I never actually completed the install.

The extension was a down stairs shower room and utility area. When I done it I put in a new lighting circuit, new ring circuit and shower circuit, all wired to the mains in the garage. Existing was a 10 way crabtee split load, with all the existing wiring. Next to it was a proteus 4 way board which only had one lighting circuit attached to it.

About 6 years ago I just connected all the new circuits onto the proteus board.

Well today 6 years after I started I finally decided to change the board and get everything on an RCD, using a split load board I purchased 6 years ago.

Obviously it was pre 17th edition so was main switch type with 30mA RCD on the other side. I've connected all the ciruits from the proteus board onto the RCD side of the split load, inc shower lighting circuit, sockets and shower, but I haven't touched the other board that has the rest of the house wiring in it.

So everything on that board complies to 17th Edition. I do mainly commercial works and not much domestic, but next month I'm wanting to do my Napit assesement and was going to use this as an example. I have done the bond to the main gas (which was at the opposite end of the house) but not yet the main water as its abit more akward.

I guess what I'm asking is will the assessor accept just looking at the board i've done today or will I have to test the existing installation and move the existing upstairs lighting circuit onto the RCD side, because there is a bathroom upstairs??

I assume he will want to see that I have actually bonded the main water, since its taken me 6 years to complete the extension.

Also will he want to see the LABC notification as I don't think it was ever actually signed off since the builder left the site before it was fully completed?

Any other advice with regards to a Napit assesement are more than welcome.

Thanks (apologies for the lengthy post)

The water bond will have to be done, as this is very important, like the gas bond. If you declare you only done the small sub board that should be fine, have you tested this board and filled out an electrical installation certificate, as he or she will want to see this too. You should be fine as long as what you have done is up to scratch, hope this helps bud.

Cant really add much more to what micky has said. But just make sure your assessor is fully aware that it is the 17th compliant board that he is assessing you against and not the rest of the install. Make sure all the conductors in switches are properly sleeved, grommets are fitted etc, you don't want to fall over on minor detail. I cant comment on Napit assessments because i am with Elecsa, but i would imagine they are all similar, and I know Elecsa are keen on the finer points like sleeving, warning notices, IP ratings and such. These assessors are also very keen with the paperwork and accuracy, so make sure that your schedule of test results accurately reflect the actual test results on the install.

Good luck

just hope the assessment doesn't take 6 years, you'll spend a fortune in tea and kit-kats

got a similar problem Iam doing my napit assesment within the next 2 weeks just paidup and sent my application over, I have done an install in my parents garage put a ring main in and a lighting circuit and put these 2 circuits on a new board with rcbos and not touched anything on the original board, the gas is very clearly bonded but there doesnt appear to be a water bond well it isnt next to the stop cock which is strange as the house is only 15 years old i phoned napit I didnt mention about the water bond but asked if I would only be assesed on my little install and they said yes.

So surely anything on the original wiring isnt down to me is it? But none the less I need to get the water bonded just not sure I have time before napit come round.

What do you guys think

Technically, because the design was done to the 16th, even if construction starts after the 17th came into force, the installation can still be installaed to the 16th, and appropriate certification issued.

Thanks guys, I guess I should get pulling in the 10mm water bond then, oh the joy

And my mum doesn't even make me a tea!

Cant reall add much more to this as micky and howard have nailed it except coffee and Kit kats like tel has said but for brownie points get him a kit kat chunky and good luck
