Hi all you electrical specialists out there. Following a five-year fixed electrical test, it has been noted we need to change our fuses for our lighting and socket circuits, for the RCD type.

This issue was not picked up on the last inspection /test (4 years ago) and I didn’t think that changes to legislation and codes of practice are generally intended to be retrospective. Is this a case that they are retrospective and the last person missed this issue or are the new company taking us for a ride?

Is there something official I can refer to either way, when either going back to the company or convincing those upon high to agree this work.

Thanks for any help

Chris

These requirements are laid down in BS 7671. Lighting does not need to be on an RCD. Sockets on the other hand do, and this was the case even in the last amendment of the regs. 

The link below will provide you guidance on this.

Chris42,

Where in the country are you please?

Can you PM me with an email address, and send me the report & I will willingly make comments on the EICR.

Yes, I am more than competent to do this, and actually undertake the EICR if needed.

However, I am not looking for the work, what I HATE, is contractors who potentially drum up work from false requirements from remedials that are not required.

I am not stating that this is what has happened, but, it is not unknown.

It will be awkward to discuss this in open forum, as it will mean publishing the document and thus identifying all parties involved, which would be unfair.

Obviously the decision is yours, but, I am offering to do this for you as a fellow IOSH forum member, in the interests of trying to show that not all electrical people are out to tuck their customers up.

The requirement for change depends on the exact specification of the installation, it is not black and white.

There have been changes that have increased the requirement for coverage by RCD's, across both sockets & lighting, however, without seeing the reasons, and having more information on the installation then it is impossible to state what is required.

Thank you both, it seems from your posts there can be retrospective requirements.

I have requested a copy of the report, as I have only seen the quote so far which states " No RCD Coverage for lights and socket circuits, requires 18 RCBO's to be fitted into fuse box number two (c1)".  With C1 meaning requires urgent attention. This has an approx. cost of £780 for this element.

They have said to the manager that as they are members of NICEIC they actually checked the RCD issue with them first. It just seemed odd that this was not noted previously and is something that requires urgent attention.

Paul - Once I get the report I will take you up on your kind offer and PM you my contact details.

Thanks

Chris

As an aside and apologies to Chris for hijacking his post, but what is a reasonable timescale for C2 & C3 remedial works from an EICR to be carried out i.e. days, weeks, months?

Chris,

Changes in regulations such as that requiring an RCD from Amd3, will never, I repeat NEVER, result in a C1 code on an EICR on a circuit which is otherwise compliant with all other aspects of previous editions of BS7671, especially if it was compliant when it was installed.

The person coding the absence of an RCD on an otherwise sound circuit which is only now a requirement following the publication of Amd3 to BS7671 is incompetent to be coding.

C1 means immedate danger to life is present, a simple and easily undestandable example is exposed live parts, which can be touched, thus resulting in an electric shock, which is generally viewed as a fatal outcome.

Ray,

This is a mute point, there is no defined timescale.  In fact a C3 does not even require any redress what so ever, as it would not result in an unsatisfactory situation on an EICR.

I have heard that some insurance companies are requiring C2's to be remedied in months, so < 1 year, but, that is hearsay, not official, and there is no guidance, it would be down to the competent persons engineering judgement as to how dangerous the C2 is, as it were.

C2 is potentially dangerous, in that it would require two simultaneous faults or actions to be dangerous, for example.

A simple C2 that many can understand would be a gas or oil pipe providing the means of earthing for the installation.  This is a latent defect, i.e. a fault, as it is not allowed, however, it does not become a real and present danger until there is a second fault in the installation allowing current to flow down the earthing system to earth through the gas/oil pipe, with all the, then, dangers of using a pipe carrying a flammable substance to carry the prospectively high fault currents that should be generated in the event of such a fault to instigate ADS in the electrical system.

Paul Thank you for your erudite response which answers my question perfectly - every day is a schoolday.
