EICR unsatisfactory due to 'no RCD protection to lighting circuits'

Hello - sorry to resurrect old thread but it seems to be along the lines of my issue.

I am a landlord with old Volex CU which only has RCD on sockets - EICR inspection has C2's it as no RCD on lighting circuit but reading this thread and spekaing to my usual electrician from London, it would seem it could be a C3 - can anyone advise me please?

Many thanks

Bradley

C2 is perfectly justified in this situation. Its down to the person who is signing the certificate whether to c2 or c3 in this situation.

No it is not. BS7671 does not require RCD protection in these circumstances, so it cannot be a C2.
IET decides the rules, not NAPPIT etc

Can we see exactly what the C2's are for please? Ideally a photo of the consumer unit too. We can then give much better advice.

If it's simply missing RCD protection for lighting, then BPG4 (best Practise Guide 4) has that as a C3.

(It's been interesting to me since joining NAPIT that an awful lot of their members distance themselves from Codebreakers, including some of the leadership (in private).
There's in fact a thread on the Napit forum asking how is it that Napit contribute to BPG4 yet publish a book contradicting it! I've yet to buy enough popcorn to read the thread to the end!)

C2 MAY be perfectly justified. But I disagree it IS justified.

we code to the guidelines layer down. Nowhere does it say in any guidelines or regs lighting circuits without RCD protection in domestic are potentially dangerous.

other factors in the lighting circuit may justify having the lighting as C2 but not just being without RCD protection.

it’s down to the individual tester. Yes but within the guidelines.

I hate showers without rcd protection, but I don’t give them a C2. I can’t. Unless another issue arises that justifies it.

He is having none of it and also says I have to have earth going to switch and light, even if using a plastic fitting - Grrrr

Good for him. If he changed his mind we'd be moaning. Get the work done, as requested by the only electrician who has been on site and deemed it necessary.

Hang on a minute! This was a thread about no RCD, and now it's no cpc.
Same applies though. Lack of RCD and lack of cpc are not C2 per se, if the wiring hasn't been recently modified and was installed to regs.
It's the inspector's decision, but that decision must be made to the guidelines of BS7671, not his personal opinion, or that of a jumped up trade body.
Opinions should be offered in the comments.

You can’t C2 on a whim.

personal feelings, and maybe the tenant will do this or that cannot go into an EICR.

state fact and code appropriately without prejudice.

I'm with Buzz, I'd C2, while industry guides dictate a C3, they are just that; Guides. The inspector may have used thier engineering judgement, the fact it is going to be let out, the fact that this may involve children or unskilled persons DIY (The latter being thr only one that can be controlled by the letting agreement).

There may be further underlying factors as suggested but even without that you're looking at a 2 bed property with a reasonably high likelihood of being rented to a family and so putting forward the requirement for RCD protection is prudent.

Thr client needs to realise they have responsibilities to take necessary steps to foresee matters that may arise during the time the premises are let.

Aside from the obvious elderly persons market there should be zero reason not to have RCD protection in this day and age. The house is nearly 24yrs old, while in the scheme of things it's not old (compared to houses of the 60/70s) we've had the requirement for RCDs for that past 12+ years, that's half its life, and you're telling me we shouldn't be improving these Installations?

I'm sorry but I'm with the inspector on this one purely on the basis you can't Guarantee the type of tenant and so should be planning for all eventualities, no RCDs in (let) properties in this day and age is frankly irresponsible.

To put this all in context, it's been a requirement since 1966 to have an earth (cpc) on a lighting circuit. The idea that electricity should have a safe way back in fault conditions is very much tried, tested and beneficial.

BPG4 slightly controversially says that if the fittings and switches are class II (plastic) it's only a code C3; this is in fact contravening another part of BS7671 that says class II protection can only be used if the installation is supervised (i.e. not a house).

It should also be noted that BPG1 says:

Even if as a literal interpreter of BPG4 I said the installation was just about satisfactory, my next words would be "but I highly advise the lighting is rewired and RCD protection is provided for all circuits. These investments would last for decades and the cost per month over the lifetime of them is almost nothing.

I've been reminded by @Lister1987 that this is a rental property, all the more reason to get it up to scratch for the tenants safety.

I have not fitted a single domestic circuit that wasn't protected by an RCD since around 1980. The customer was given no choice in this. Take it or leave it.
BUT, the coding for scenario in this thread should be C3. It's a statement of fact at that moment in time. What might happen before the next inspection is irrelevant You are there to test to the 18th edition, and the clause referring to installations done to previous editions covers this.
You can recommend what you think is required in the strongest terms, up to the point of refusing to issue the certificate and walking away without payment if the landlord doesn't agree to your recommendations, leaving the landlord to find someone else to test.

Without seeing his wording I cannot give a definitive responce, but from what you say , he is wrong.

I missed the bit about no earth and no rcd in the lighting circuit. I though it was just no rcd protection.

this changes things significantly.

is there anything else.

I really need to see the actual wording of report before condemning or agreeing with the electricians EICR.

I may have been a bit premature in my responses.

RCD protection in accordance with regulations BS 7671 is classed as additional protection & not fault protection.But under regulations relating to the 16TH addition bathrooms containing a bath or shower required RCD protection if supplementary bonding is not in place. Supplementary bonding comprises of a 6mm earth wire earthing all extraneous conductive parts ( metal bath, shower , pipes , towel rail etc) so that under fault conditions where one becomes live they all have the same voltage overcoming risk of electric shock as to get a shock you need to touch between different voltages as in if the bath is 230 volts & the pipe work 130 volts the fault current will be determined my a 100 volt differential.Under the 17 edition the bathroom is described as a special location due to additional risks.I don’t blame the electrician for a c2 as I have attended 2 emergency call outs where pipes where live endangering life which would not have been the case with an RCD. Another thing to consider is where the consumer unit is located. If it is within a fire escape route & made of plastic rather than metal it’s a code 2 as fire regs are incorporated within electrical regs now. With my 33 years experience don’t blame a guy for being cautious when electricity is involved

Interesting discussion. On the subject of coding:

BS7671 does a reasonable job of telling us how an installation should be. It doesn't, IMO, do a very good job of telling us why an installation should be like that, and what dangers result from a particular non compliance or defect. The chapter on periodic I+T can be read in about one minute. Regarding RCDs for additional protection, it tells us we should code a minimum of C3 (guidance from model form). Other than that, it offers no more guidance on coding, leaving it totally up to the the inspector to decide. This is why I think guides such as BPG4 and codebreakers are necessary.

Codebreakers seems to take a bit of a bashing for coding too harshly, and, while I don't code to the book myself (I prefer BPG4), I do wonder if the criticism is a little unfair sometimes.

For example, I believe codebreakers offers a C2 for lack of RCD protection to cables passing through walls containing metal parts, and for cables buried in walls <50mm. These are both C3s in BPG4. However, there have been deaths that would have been avoided had RCDs been in place for the above circumstances, so I can kind of see why codebreakers is offering a C2.

Also, coding can be confusing. Lack of supplementary bonding in a bathroom, C2. Lack of RCD protection to bathroom circuits, C3. Add RCD protection to the bathroom, and the C2 goes away. So how can lack of RCD protection not be a C2? Difficult logic to get the head around sometimes.
