The Future of Fuse boards...?

Looks nice

There shouldn't be a chimney effect as there should be cavity barriers for this purpose.

 

[mainline]

Totally irrelevant. And there is nothing in the Regs about making a CU 'airtight' , if anything that's counter productive as we're told to install in such a way to minimise the build up of heat or words to that effect.

As far as is reasonably practicable, to contain any fire within the enclosure or cabinet and to minimise the escape of flames.

Won't be long before everyone is filling a consumer unit with expanding foam

 

[Dave OCD]

Don't give anybody ideas ! Can you imagine trying to add a cable to that ?!

Intumescent foam, of course.

 

[Dustydazzler]

I can just imagine Delroys face when he turn up to do a Youtuber domestic board change this year only to find some sparky has completely filled it to the brim with builders foam...

NO WAY NO WAY A QUALIFIED ELECTRICIAN DONE THAT I CAN'T SEE IT

Might have been before the sparky pulled them out the way to get his cables down.

Imagine telling a customer that they need to spend a load of money on a new metal consumer unit, telling them how much safer it is in a fire and then leaving a dirty great hole in their wall partition.

There is no argument for not sealing it up.

Here we go again

I tried using that naff grommet strip, including super gluing it, never stays it place, even when carefully inserting a larger cable. Hager bespoke grommet is the same. Manufacturers should come up with something more substantial.

 

[freddo]

We use a much deeper grommet strip (similar to this) than the silly short stuff the wholesalers stock.

people C2 open backed wylex boards on a flammable wall if no paxolin sheet, but then wang a load of these knockouts out for 6 cables to come in

I think that most people would know what Brian meant when saying “airtight”.

Also, I don't understand how you can disagree about leaving a dirty, great hole in a wall cavity.

Have a read of section 527.

Has the penetration breached a fire compartment because if not no further action is required.

The metal CU should be treated as a form of fire barrier/containment, that being the whole reason for having metal CUs in the first place.

Cutting a hole that size in a wooden partition and leaving it cannot be said to be the work of a decent electrician.

Fill it with asbestos. Job’s a good ‘un
