consumer unit ip ratings

[sparky351355]

does anyone know where i could download a diagram showing the minimum ip ratings on a consumer unit i.e. front/ side top and bottom with regard to ip2x/ip4x/ipxxb , thanks

no, but it's 1p4xx top and ip2xx sides and bottom.

This applies to all accessible electrical enclosures, not just CUs. So, for example, if I have a surface light switch, I'll generally try to run the cable into the bottom or sides rather than the top. (IP4X is a surprisingly small hole, 1mm.)

I've looked everywhere for a diagram, we have been audited on some ecr's and the --- has put a c2 on the entry hole for the 16mm earth with about a 4mm gap , I want to stick the diagram down his throat, we are being audited by ******s.

where's the entry, top or bottom. even if at top, it's only a C3.

Where's the hole? top/side/bottom?

Bottom , low level board in a mains cupboard !

U don't know the half of it mate , pull chords 2.4 m high in a bathroom.....c2(in the zone 1 apparently . Small chip on low level cooker out switch on side , filled with cork ......c2. *removed*

My understanding was as far as consumer units are concerned top and front IP4X, sides and bottom IP2X / IPXXB.

My understanding was as far as consumer units are concerned top and front IP4X, sides and bottom IP2X / IPXXB.

All surfaces at least IP2X. Readily accessible horizontal top surface at least IP4X.

See BGB 416.2.1 and 416.2.2

Might do my own diagram!

the muppet wants reporting to his or his company's scam provider.

I agree the bloke does sound like a tool but teletrix i thought holes in the top bigger than ball point pen (ip4x) was a C2 as the ip rating is compromised and dust etc could fall in and cause a short (v likely i know!!) - i always stick it down as a C2. Maybe i'm getting it wrong...

 

[telectrix]

bit of a judgement call. if CU is situated in such a way that it's easy to poke something in, then a C2. if it's close to, say , a ceiling, then a C3, IMO.
