Regulations do not apply to commercial buildings, Document M may not apply either otherwise it would be 1.2metres high max.

Which regulations don't apply to commercial buildings

Quote from Consumer Unit regulations 2022
The particular consumer unit regulation relating to this in the 18th edition is 421.1.201

It should be noted that this regulation does not apply to commercial installations, where plastic consumer units can still be installed.

Not only that, but in domestic outbuildings, for example sheds & garages, you can still install plastic consumer units assuming that the outbuilding is not joined to the main building.

There are some regs that only apply to certain types of building, non combustible consumer units is of course one of them.

but to say regulations do not apply to Comercial buildings is simply wrong,
some Comercial buildings have far more regulations that apply to them than domestic.

Consumer units installed in domestic premises have to be non combustable there is no absolute requirement that they MUST be metal and the reg you quote says exactly that and only uses metal as an example

Agreed . 421.1.201. Ferrous metal is deemed to be one example of a non-combustible material that meets the intent of the regulation.

Might want to have a read of the Approved Document M:
In particular pages 44, 45.

Slight subject tangent. Non-combustible vs metal vs plastic consumer units. Been covered before.

As for consumer units fitted to ceiling… may be ok as per regulation, but the lid shouldn’t hang down.
I’m thinking faulty circuit breaker… user looking up to reset and the thing blows in a shower of sparks.

Might let any water drain out though.

You can order those from the ceiling types from the batcatalogue they come has standed black so you can't see them in the dark.

 

[telectrix]

i agree with you, ref: post 10
just wondered if you could help me back it up with something easy to quote!

the electric will all fall out.

We seem to have extrapolated much from the sparse information provided by the OP - most of which isn't relevant to the questions asked.

Is it okay to mount a DB on the ceiling?

Is it okay if the cover opens downwards?

The only unknown is whether or not the lid has some means of retention and the OP has declined to comment further, despite having been online this morning. I'm guessing that it does.

If it is domestic, you could say that the enclosure will not contain a fire as the plastic parts are not contained within a non combustible enclosure unless the lid is closed.
a check with the manufacturer of the board would be a good place to start.

Sorry, the lid does stay shut
