C2 issues? Consumer Unit & Circuit forms a Figure of 8 Rather than a complete RFC?

[LEighLeigh]

Please help, just had a domestic EICR undertaken, a C2 issue: Consumer Unit does not meet minimum I.P rating, what does this mean and how do I check this out? how expensive to rectify? thanks!

the CU has cable entry holes, these should not be > a certain sizeover and above the cables. . i.e. top is 1mm clearance. sides and bottom are finger size. if not too excessive, some filler would suffice to seal. a picture would help

Nine times out of ten I never view this as a Code 2, can you show a pic of your consumer unit.

 

[LEighLeigh]

Unfortunately this is the only pic I have, not ideal ( I don't live in the property ), I'll try and get a better picture soon

 

[LEighLeigh]

Also I'm told the 'FI' is really a 'C2' as it requires further investigation. I'd really appreciate some help with that, any opinions welcome please

 

[westward10]

From the pic it is impossible to say the extent of the issue.

Yes apologies for that, what does this mean: Circuit forms a Figure of 8 Rather than a complete RFC - is that a C2? He's put FI but in his text msg to me he says that it is a C2, confused

FI means further investigation. this leads to an unsatisfactory report, same as a C2, but in a different way.

as regards the CU IP rating. there are several methods costing very little. a piece of plastic could be cut to fit and glued over the offending hole/s. blue tak, filler.anything that would stop penetration of the enclosure to the relevant rating.basically one does not want a customer to be able to poke a finger in and come into contact with live parts.

really appreciate the replay; what does this mean: Circuit forms a Figure of 8 Rather than a complete RFC - do you come across this a lot?

 

[westward10]

The fact it has been verified as a figure of eight means it doesn't need investigating (FI) it is what it is. A ring final circuit is as it says a ring or a circle a figure of eight is as it says an eight, just imagine them. Is it dangerous, no providing the connections are sound it is just non conventional but does indicate the circuit has undergone non compliant alterations.

I see you're in Swansea... is the property also in Swansea?

It could mean that two RFC have been cross-connected, so instead of circuit 1 ends A and B going to MCB1 and circuit 2 ends A and B going to MCB2 you have 1A and 2A on MCB1 and 1B and 2B on MCB2.

It is quite dangerous as you now have 64A of total current before they trip on cable designed for a 32A circuit so a cable fault could result in serious damage or even a fire.

Less obvious is someone switches one MCB off to isolate the sockets and discovers in a careless way they are still live from MCB2. Careless in the sense they did not follow a proper safe isolation procedure to actually check the accessory they are working on really is dead.

It is indeed

OK if it really is just a loop connected to a 2nd loop, less of a concern than cross-linked RFCs.

Is there any way of telling from the EICR report?
