PIR coding

[Sb8389]

Hi guys,
Doing a periodic on a cabin which is to be used for buisness use.
Its a new install and the one thing i have seen which im not sure weather it warrants a code or
not is they have a chandelair type fitting where the bracket is screwed to the beam,
Meaning due to the size of the fitting its possible for someone to put there hand above the
fitting and go into the connection behind it.
The height from floor to the fitting is 2.25m
would you guys snag this.
thanks

The top surface of an enclosure needs to meet IP4x regardless of how high it is above FFL

It's one of the first places you may put your fingers to steady yourself to remove the bracket etc. If my mental image is correct.

Just a bit confused why you are doing a pir on a new install , but as others have said the top should be sealed

416.2.2 - horizontal top surface of an enclosure which is readily accessible shall provide at least IP4X (I've not typed word for word)

2.25m above the floor is not readily accessible to my way of thinking!

If the connections are properly done within the 'cap' then it should still meet IP2X and not pose a hazard with regard to a finger touching a live terminal , who would be stupid enough to poke fingers in there anyway ?

2.25m is within arms reach when standing on the floor, hardly inaccessible is it?

Plus of course the fact that someone has to gain access to the light fitting to change the lamps means that it must be readily accessible.

I thought the reason for the ip 4x was stop the ingress of foreign objects not just someones fingers

Its not as if someone could accidently poke their fingers into something that high! This is similar to ensuring any cable connections are enclosed in an enclosure that requires a tool to gain access. If somebody wants to get a stepladder and don't know what they are doing then they deserve all they get!

The other reference I've seen with respect to 'readily accessible' is the top surface of a consumer unit that is situated immediately below the ceiling, does that need to be IP4X? Especially now when using metal enclosures that in some cases have larger cable knock-outs.

What's all this "above 2.25m" and "readily accessible" chat about ? As far as I am aware the regs make no allowance for these factors and just state that all enclosures shall be IP4X on their horizontal top surface.

I stand to be corrected though


EDIT: Just read the wording of the reg and corrected myself

Yellow van man has the correct reg number to cover this but i would agree with others that it is readily accesable

And by the sound of it , so are the connections.

I was kind of meaning that I have always maintained IP4X on any enclosure regardless of accessibility. Glad to be corrected by me reading the reg properly though. Though without a definition of readily accessible.......... nah that's another debate.

That is your perogative in interpretating the regs!
