Fire rating of fuseboard

[Calebp43]

I recently came across a video on YouTube and the guy fit a fuseboard. Very tidy job but I was confused as he used couplers to have the board not flush with the wall and there was massive holes in the back where the cable comes through.
1) doesn't it need to be ip rated so nobody can get there hands in?
2) doesn't it need to be fire rated?

Just posting this as I want to know if there is a flaw in my thinking somewhere. Here is the link to the video -

Have seen quite a few YouTube celeb Sparks space off a board from the wall using conduit couplers or a 2 inch off cut of pipe for example. Giving them a nice space to bring all the cables round under the board and in Via the back.
A consumer doesn't need to be Fire Proof / Rated. It needs to be constructed from non-Combustible material e.g Metal.
If it is spaced so far off a the wall that you can reach your fingers underneath and poke your fingers in Via the back then it would fail on IP rating. I believe sides and back must be IP2X. But from a Video its hard to tell how far one can poke your fingers inside.
Much will depend on how skinny your wrist is and how long your fingers are I guess.

"How long do you want your fingers?"

" I'd like to keep them"

Or preferably this (example)!

Some manufacturers sell stand off brackets for their consumer units

I do like to space a board off the wall a bit for 2 main reasons...

1, it allows you to bring all the cables in from the back and thus keep all the sides intact
2, often garage walls are not straight so by spacing off the wall a bit you avoid having a twisted board

An inch off the wall there is no real someone can get all their fingers into the rear knock-out, not unless they have incredibly long fingers

I've always used 2 vertical 2x1 pieces of wood when doing this, sometimes with a piece of ply across them if I'm feeling generous.

Wouldn't it be being able to touch live parts with a standard finger and not just accessing the board? Going through the back is usually much simpler in domestics.

I prefer the busbars to have a cover instead of the the barriers like in the fusebox boards, some of the better ones are IP2X with the cover off.

He should have fitted SP+N rcbos as an N to E fault could still trip others.

Is this something you have experienced? I don't generally fit DP rcbos. I like that they make ir testing easier but I don't feel it's worth the extra expense.

Yes, I have experienced this many times, twice I recall on outside lights that had water ingression.

Any ideas on what would cause that?

Leaky fittings and/or condensation.

Isn't the correct term Single Pole and Switched N. Not DP

Neutral earth faults where you can get circulating currents, particularly on tncs systems

Unless you disconnect the Neutral, the fault is going to remain
