BG consumer units

As above, plus the lid must close when subjected to gravity!

Really?

Not sure BG have released a AMD3 one yet.

Really?

As far as I am aware yes. Think about it; what is the point of a metal enclosure to help contain a fire if the front flap can be left open exposing the plastic blanks and breakers, which would melt and allow for fire to 'escape' easily.

All the Amd3 boards I have seen have the un-proppable flap!

I can see your point but, as far as I'm aware, it's not a stated requirement for the lid to close under gravity.

I think the BG one has metal sprung catches which hold it closed (assuming that it's been closed in the first place).

I've got one in my home and was going to replace it for a new metal one
Looking around found
The BG consumer unit, I was looking at
95340: 20-Way Metal Consumer Unit & 100A Switch

figured be a direct swap as they looked a like
But turns out just the back is metal and the front is some plastic
What is the full requirements for Consumer units AMD3 for well less than 30 days away

Duane, why change your board if there is not much wrong with the previous board. I am not sure if the first assessment requires very recent work. For my 1st assessment with NAPIT I used a board change I had done three years previously! Maybe niceic are different tho.

Must admit, never seen a part plastic part metal board as far as I know of. Ib personally like the new metal enclosures, find them easier to work with than the insulated ones.

Except for the BG one in the link that is! I am starting to wander where I read the flap bit now...I know I didn't make it up!

Maybe it does comply Tel, and I have been fed some misinformation.

 

[telectrix]

it may be that the flap clips in place and needs a bit of a flick to get it to drop.

What a load of cobblers,the sort of misinformation that soon gets into every day sparking folklaw then gets written up by NICEIC as THE LAW.

Having spoken to the regional manager of BG at my local wholesaler last week on an open day come & see our wares type thing; I can pass on that BG have written confirmation from IET that there is no requirement for the front flap/lid to be hinged from the top.
They have conceded that there may be a requirement for the flap lid to hold in the shut position to complete & full metal faced enclosure. As has been stated BG achieve this by having retaining catches on the flap/lid when it is pushed shut where as others rely on gravity to drop the lid/flap.

I've fitted a few BG Amd3 boards, I don't particularly like the lid hinged at the bottom, but I use this one if I need the main switch on the right - mainly because it is reasonably priced (cheap). When mounted high up, it is sometimes a pain to try and see anything due to the lid being in the way, unless you get out a step ladder.

I used to use Wylex for a RH main switch, a nicer board, but their Amd-3 boards are a bit pricy for the moment.

And I use an MK one if I need the main switch on the left - which has a much nicer lid hinged at the top.

However, I have noticed some places selling "metal" consumer units that are old pre-Amd3, and forgetting to mention they don't comply from Jan-16, leaving unsuspecting customers to get caught out.

Yep I agree, cobblers it is in the sense there is no regulatory requirement. It comes under good practice in my view. Having thought about it where i heard it from was either general guidance from either NAPIT or one of the manufacturers (when Amd3 first came about).

Regarding the bit you say about the BG saying there may be a requirement is wrong though. In my view there is definately a requirement for the lid to hold in a shut position, otherwise the fire containment is not maintained. Wiring Matters article on this states the enclosure must form a complete envelope.

One reason I am not so keen on the bottom hinged BG CU, which I have only just become aware of, is Joe public could have a loose neutral tail causing RCD to trip. They may leave the flap down if the tripping is problematic for a few days before getting round to calling a spark. In the interim if a fire arose then the remaining steel enclosure is not much better than a chocolate teapot!

Having said all that, and despite my preference for steel CUs, I do not think insulated CUs should be effectively (for all intents and purposes) banned from domestic use.

I shall get the Eyre & Elliston manager to chase up the BG fella to email a copy & by all means Ishall post it up.

and a cow could fly past the window and fart the lid open.
