1st day back at work today after a long lay off nothing much to do so the internet beckoned. I decided to have a look at Amd 3 and was amazed at some of the disinformation coming from some of the Distribution board manufacturers, I read and printed off a copy of amd3 from the IET and it clearly states " domestic consumer unite shall be made of non combustible or a not readily combustible material " Where as virtually the same document from a well known distribution board maker (beginning with H~~~r) saying that the domestic CU must be made from NON COMBUSTIBLE MATERIAL scare mongering or what?. I appreciate it's a work in progress but someone ought to take these people to task, we should wait until Ammendment three is ratified before jumping to conclusion, what are your thoughts?

I agree with you young man . There are already fuse boards on the market that will be ok to use , so why not tell us ones that can't be used . To easy ?

its a shambles , picture this..........

after the introduction of the 17th regs virtually everyone in the UK was rushing round to get the new fangled dual rcd boards fitted in their gaff , millions have been slung in , nearly every one plastic.
just as this near monumental task is nearing completion , latest regs now imply - " sorry , should be metal"

Quite frankly , the word on the street is that bs7671 are stepping beyond their remit in any way trying to dictate what kind of product gets fitted , and secondly , the construction worthiness of a product should remain solely under the jurisdiction of the British Standards committee and not the dithering duffers at the IET sticking thier oar in.

the IEE as it was then, in the 90's, made the wiring regs. a british standard in order, so they said, to stop johnny foreigner interfering with our wiring regs. suddenly, in the early 2000's , they then decide to allow said johnny foreigner to alter the wiring colours from what has been used from the year dot, to stupid indistinct, nondescript shyte. so much for british standards.

Pete, you as regular reader of these esteemed forums, I'm suprised you haven't already seen the thread about this bollox.
The conclusion was, that it's bollox.

NIC in their wisdom have been spouting that the only way to comply will be sheet steel.....sounds like a load of sheet to me. It would be infinately more sense if the IET introduced an amendment outlawing single screw cage clamp terminals on main switches and making deep tunnels with two screw terminals standard. CU enclosures could then be made of kindling wood and there still wouldn't be any fires.

and, as geordie spark has pointed out a couple of times.... terminals with more than a couple of turns of thread on them.

That is vaporization of zinc; one that comes up in welding, don't weld galvanized.

Yep, vapourizing zinc is a severe health hazard on its own but the biggest problem is often when the steel becomes hot enough for the zinc coating to liquidize or melt it then runs off and drips over anything in the vicinity causing those things to spontaneously combust.

where do you guys get your bakelight/pakeolin from for your new ccu installs or are you going to add a plastic header?

I want a free copy of the regs and OSG too as these basterwards have got nothing better to do but cost us all money and our clients too for stupidness caused by unskilled labour,I agree that mainswitches should revert back to the switches like the 5419 of yesteryear to which I have never seen one wooden backed old wylex that showed any signs of heat damage after being installed for over 40 years,the amount of old switchgear of that era still in service and still going strong is a testament to the sparks of that time and also the quality of kit available,nowadays cheap as poss and thrown in.So non combustable is really going to solve the issues then,think not IEE.

I was in my local wholesalers yesterday (independant) and there was a BG rep trying to get them to sell his gear. I asked him about this plastic/metal CU thing. He said nothing is concrete yet and they are working behind the scenes to get it dropped. I took this to mean current plastic BG boards will not be ok!

As has already been stated above, they would make all CU/DB plastic or metal, far safer by calling for the reintroduction of twin connection screws/clamps on all main switches and protection devices.

Oh and BTW someone mentioned Wylex wooden backed 3036 CU's, Wylex have never made a wooden backed CU, they made wooden frame ''Open back'' CU's. But he was right about never seeing one catch fire internally, nor have i and i dare say no-one else has either!!

I found one that had obviously had a nail for a fuse or something at some point and there was a hole burnt entirely through the back board and the old fuse carrier (safely protected with insulation tape!) was significantly the worse for wear, but the wooden surround was not harmed at all and the rest of the CU seemed OK, just lucky I was changing it.

Looks like the M&Q regs were right from the outset, everything metalclad.


We all know this is a load of b0££oX. So why perpetuate an unsubstantiated rumour?

Wait until the yellow book arrives, in the meantime STOP PANICING!



At one time electricians were noted for their logical approach to things. Headless chickens is more apt nowadays.

I may be missing something here but in the images Iv'e studied relating to consumer unit overheat/fires.
Its the internal components that show heat damage and bugger all to do with the enclosure being plastic, (have a look yourselves)
Most of these problems are down to loose connections from what I see.
Its the 15th all over again, and back to the days when a terrified young mother is walking her toddler passed a building site to be confronted by a loony sparky with his shiny new copy of the regs book a 10mm bond and clamp that he instantly attaches to her little one's buggy.
