Not with the live to neutral loop impedence value measured it wont!

Onevery last question; why do the DNO bother to install an incoming service fuse if on TT systems, the fuse is unlikely to blow and protect the circuit?

How nice. At least I will have the comfort in knowing I wont be paying the miserable money grabbing B*stards for pulling the Service fuse and resealing it then. :mrgreen:

To be honest, I didnt ask. Seeing as they have been notified 3 times of a door that is hanging off the meter box with no engineer. Unfortunately, the only point would be upstairs by the henley block, which is pretty pointless.

Well, if you want to suggest how I am supposed to do that with rec requirements for a switchfuse with all tails >3 metres, be my guest... same with a tt supply and associated earth blocks... Bearing in mind a month ago, I had a plastic enclosed CU in the meter box, with all circuits routed up...

What I meant was, the metal adaptable was swapped out for the plastic enclosure the day after, with another smaller adaptable where the current (big) one is currently. As the new adaptable is plastic, I take it induction will not be a problem? Finally, bearing in mind I want to up the supply...

Why not may I ask? Also, how best would I approach the chap about putting it right? There is nothing worse than someone telling you your job. He did, bar the pretty big f*ck up with the RCD protection on the tails, a very good job IMO, so how can I avoid ruffling his feathers?

Was put there temporarily.moved following day to where the metal adaptable is to house 2X100a henley blocks to join the 25mm SWA and the tails. At that stage was purely there to house thejunction between 2 2.5mm cables. Overkill, but its all he had at the time. Would you agree getting the lad...

Unfortunately, there is no guarantee that a registered electrician will do a good job either... as I have just discovered.

I doubt there is space for that now after 2 days work to relocate the CU, plus he is going to need another day for testing in the future, 600 quid total for what isincreasingly sounding like a botched job. Its been sightly modded since, but this is what it looked like after day 1: I...

Will do cheers. Domestic installer with 5 years apprenticeship and 5 years in the trade. Will get some photos on my next visit, sounds like the easiest solution may be to get the DNO to get me connected up to local TNCS supply when they come round next; will solve most of the problems. Only...

So why the hell has a registered NICEIC electrician wired it up without one then? I thought the whole point of these bloody schemes was to ensure the work was safe?

Sure. But the SWA is deeper than 50mm, so would have thought on top of the earthed mechanical protection, no RCD would be required? THe Switchfuse was placed to meet the DNO requirements for one due to the length of the meter tails.

OK, so its less of an issue, other than I have a junction box connecting the 16mm submain and its max rating is 60A.... other issue I pointed out was I wanted the system to be easily upgradable to 100A, which I cant do now without the later addition of a 60A switchfuse, which is a massive pain...

Thanks, its protected by a BS88 80A fuse, why does it need RCD protection as well? Disconnection times? Its currently protected by a switchfuse after the supply fuse, I would have thought that RCD on the 25mm SWA would have been overkill as the SWA is earthed too? As for the submain, I...

Unfortunately, the job I have to do involves 2 radials wired into the CU as a ring. No continuity, so having to rewire from the CU, to every point spurred on the circuit, which makes subsequent explaination to the LABC Nazis difficult. Good job I have a ready supply of 2005 cable then...

Nope, they stamp it now with the date of production. And I question the phrase "serious fraud". Its only fraud if you get caught. Then, only if they can prove that you were doing it to get round the joke that is part P notification. Do you work for LABC or association that relies on...

I had the CU moved 3 metres and had all the wiring removed from the wall cavity... I have 25mm SWA bringing the supply up the cavity now, where its split in henley blocks, 25mm tails to the new CU and 16mm tails to a sub meter supplying the annexe. There is no Overcurrent protection on the 16mm...

cheers. Just had some work done by a decent registered chap, reccommended, who hasnt applied overcurrent protection to the submain before the submeter and has used a type B, rather than type S RCD.... :roll: 16mm is in trunking until it goes beneath the floors
