Consumer unit as recommended by governing body

[Pete999]

Hi all, I phoned my governing body yesteday to ask the dreaded question about TT system with metal consumer unit. His reply was that a tails gland should be used with clamp for tails in board and a 100mA rcd as main switch to protect tails feeding 30mA rcd's. He also said a fire resistant material should be used in plastic trunking above board to stop fire escaping past holes where cables enter the board and setting the trunking on fire. I said I thought as long as ip ratings for horizontal and vertical edges were met there wasn't a requirement for the board to be fire rated. His reply was that anywhere air could get in or fire could escape from should be sealed else there is no point fitting a metal board.
We both finally agreed that I could fit a 100mA rcd in plastic enlosure before board as it woudn't be classed as switch gear (wylex also recommed this practice on there youtube video even though I disagree and think it should be classed as switchgear).
I understand eveything he said, but where do you stop with extra expense for materias, labour etc
I just wondered how far the rest of you go and what practices you would recommend in this situation. Thanks in advance.

Governing body, do you mean scam, sorry scheme say like NICEIC and the likes

Hager - Mythbreakers story

Lee, Hagar seems to be your choice of units so I hope you don't mind me asking... I can't quite see the difference between the design 10 and 30? Is it just that the 30 comes with the accessories (grommet strip, tail clamp etc)?

Also, costwise they seem quite steep compared to wylex which is what I use at present. What sort of price are you paying for a dual RCD 10 way?

PS.. Sorry dlt for going off track on your thread.

The design 30 also has a lockable lid clasp

I'm paying just under a ton (inc VAT) for a 5+5 design 10 with breakers

That's pretty good Andy, where's that from?

I'm paying similar money to Andy from believe it or not my local CEF. You can buy populated 5 and 5 AM3 Hager boards online for around £110 inc the dreaded.

 

[telectrix]

so, basically double the cost of an insulated CU.

That's from a local independent. I believe that sentate/rexcell do some good deals though if you have one close.
