Rubber grommet on new consumer unit install - fire risk?

[terrific]

Hi All,
Just looking for some advice, had a new CU fitted and the installer incorrectly drilled a cable access hole in the side of the CU. Once he noticed the mistake he just fitted a rubber closed grommet.

I'm a little unsure if this meets the requirements as surely the whole point of the new(ish) metal CUs is that it will contain fire. Obviously this will now not be the case?

Any advice greatly received,
Thanks in advance,

Which plane is the hole on the vertical or horizontal?
If horizontal, top or botom?
Can you see the hole or is the hole up against the ceiling?
Is there any chance of anyone taking the blind grommet out and sticking pinkies into the CU?

Hi Pete999,
Thanks for your message - It's on the RH side, the board is approx. 1.8m from floor level. So yes its possible to remove the grommet and access.

There's nothing wrong with it. I would of used a rubber membrane grommet such as this so it blended in with the board a bit better...other than that is fine. https://www.NoLinkingToThis/p/wylex...gclsrc=aw.ds&dclid=CNPIm9XF9toCFYZh0wod2xsBHg

As lee said, there's nothing wrong with it regards maintaining a fire. I would have done exactly the same thing... however, I would also have kicked myself and sworn quietly at my stupidity in taking the wrong cut out out.

Did you ask your spark about this or did you think you would ---- on him by coming here and hoping we would slate him?

Like the customer that couldn't get the Texecom app (notifications) to work on his mobile as he thought it should work so refused to pay the bill for the whole install (he specd Texecom after some research, I'd have gone for Enforcer)

Just curious on the views of the peer community, obviously he thinks it's fine otherwise he wouldn't have left it

Thanks very much - good to hear

Assuming 20mm I would have preferred a hex nut ("bung") and lockring (or locknut) - but that said I see no issue with a blind/closed grommet in principle.

Depends on how easily it can be pushed out being it being at 1.8m Part M.

There is nothing wrong with a closed grommet

There is nothing wrong with a closed grommet

Apart from it being inflammable?

who's to say it isn't a fire retardant grommet?

Apart from it being inflammable?

As is the plastic insulation on the cables, the plastic protective devices, any plastic grommets or glands used, the paper labels etc etc

And if you want to be pedantic the paint and the steel will combust if you get it hot enough.

only thing i'd perhaps do is to put a bit of gorilla snot glue on the grommet

They have been about for years, if they are not compliant
it would be pulled.

 

[telectrix]

complaint.? or compliant?
