Hi All,

I've just had a new condition report. He's given C2 for no fan isolator which I don't agree with.
He also given C2 for the boiler being on a plug/socket rather than a DP switch. I really can't see that being potentially dangerous, what do you guys think?
Also the free standing electric cooker has the cooker switch/isolator on the wall above it. I agree there is a burn risk but C2 or C3?

Thanks,

Keith.

Can't see why a boiler on a 13A plug even warrants a comment. What's the issue with it?
No issue, as far as I'm concerned. This is a money making chancer, he's even said the extractor fan shouldn't be in zone0/1. It's actually in zone 2 and I've just looked out the invoice for it, 3 years old and IP44.
What's the deal with 10mm main earth and 6mm gas/water? It was in regs at the time of installation, isn't that what matters? Do i need to upgrade unless i'm getting new circuits added or new consumer unit?

Cheers.

Boiler on a plughead satisfies some of the requirements and probably all from the boiler manufacturer POV. The only issue i can see is that you also remove the earth connection when you un plug it. You would want to ensure that the earthing is providing protection for instance from UFH valves or zone valves or anything that is powered independent from the boiler plug top. Typically the copper pipework at the boiler is earthed independently anyway which is the best solution.
I would ask him why he has C2 the boiler just in case he has seen something that worried him.

I’m fed up reading about chancers using Eicr s as a license to scam people into unnecessary remedial work

thr whole indusrty is going down to toilet
Yep. Well unluckily for him I had half an idea he was wrong. But how many others just accept it. Not good.
Do you have any thoughts about C2 for 6mm main earth and 6mm bonding? Do I really need to upgrade unless i'm getting new circuits added or new consumer unit?

The Best Practise Guide on EICR codes says that 6mm for bonding is fine, if no sign of thermal damage and does not require a code but should be noted

10mm main earth would depend on the main cutout fuse and supply type. For PME supplies the DNO often specify 16mm - but unless it's a TT (earth Rod) then the size is what they have supplied from their equipment - and they often won't upgrade it unless changing something else...

The adiabatic equation could be used to determine the required size of main earth - and 6mm will almost always be fine.

I much prefer EICRs that list the reg number beside observations -at least it gives some idea of what basis they are stating something is dangerous...

EDIT: The BPG does say that "Absence of a reliable and effective means of earthing for the installation", so worth checking that the Ze is acceptable - that would be the only reason I could see for a non-thermally damaged 10mm main earth to be given a C2.

But in theory if you unplugged it for the report, then it isn't part of the fixed wiring (though I know there are arguments that it's not that simple)...

I really think that there needs to be a system - where they are all electronically placed on file with some suitable national body (or even a respected forum of experts ahem) - who then checks a small %ge of them manually...

From what I've seen - they would pick up so many significant errors just from a tiny percentage overview that it would force something to be done...

Also would resolve any arguments down the line if something happened, as to what was written down - so a protection for the inspectors who are doing a proper job.

The problem is two fold at the moment

1. Inspectors massively over coding to gain extra work, or because they have a copy of CodeBreakers and no experience...
2. "inspectors" passing dangerous properties with no more than a 10 minute site visit and picture of the consumer unit...

IMO, it really does depend, from an EICR POV, i would not get excited by just seeing a plug top but i would immediately look to see how all the other controls are powered, e.g. timer, valves and the pipework. It is not un-usual to see 240V going to the boiler from a call for heat of a timer or thermostat, it is not a given that the 240V originates from the boiler, hence my comment about the earth being removed when un-plugged.
