Fuse board protection against fire

[Spoon]

As an alternative to using fire retardant foam that makes it harder to add circuits, has anyone used intumescent pads? Something like this:

Intumescent Putty Pads

Provides 2 hour fire barrier at 180°C

Yes it's more expensive but looks like its good to alter for future circuits.

Why not if people are willing to pay for it, regulations are a bare minimum even if not asked for you can do more than necessary if you want too

Because why would you?

Yep, that where I saw them.

Maximum safety

I've a fear your countering a hazard that doesn't exist, no harm in it other than the inconvenience for the next spark.

Problem would exist if fast fix boxes hadn't been invented. Horrible things, I've only ever used as a last resort.
You used to be able to get proper 35mm metal boxes with 'wings' at the side, that went behind the plasterboard, and a threaded hole in the back of the box that you fitted with an appropriate length 3.5mm screw to push against a piece of wood glued to the inside of the opposite board of the wall.

useless grommet strip

For large holes which are basically rectangular, even if the corners are radiused

I've found that that plastic slide binding strip (e.g. Coloured Plastic Slide Binders - https://www.printfinishingsuperstore.co.uk/coloured-plastic-slide-binders-299-c.asp ) works well.

Car edge protection detailing strip works well too
