I agree with that, except add if has not degraded, we can advise that RCD protection is added, without needing to code it. The same applies for any other new safety feature.If it was deemed safe at the time of installation as has not been modified in any way then I see no reason as to why it needs a coding. I absolutely agree with an EICR report not being used to generate a sales lead, if you are an experienced sparks you don't have to be worried if you're doing the right thing by not coding it I find it's the less experienced sparks that codes everything just in case..
There is just one small point however, and that is new appliances which could require extra protection or modifications to the supply which are not always notified to the owner.
Two things spring to mind, one is change from TN-S to TN-C-S and the other is EV charging.
Not including solar panels as these are installed not simply plugged in, so suitable RCD protection i.e. the type of RCD used, should be selected when the solar panel is installed. My two EV chargers are class II so no problem with RCD protection or disconnection of the TN-C-S earth under fault conditions, both vehicles are e-bikes, and this is a good point, e-bikes, fork lifts, and milk floats are still electric vehicles, but they do not present the same risk as the charger is not incorporated into the vehicle.
However going back in time we had to fit an RCD to a socket outlet likely to be used for garden equipment, today the question arises what protection is required for a socket outlet likely to be used to charge an EV outside?
I have been an electrician for over 50 years, and I don't know, I look at Mode 2 EV charging and scratch my head, some leads clearly have some thing in the lead, but not sure what is in the lead, and some so called charging units have a type A or even type AC RCBO, with some saying on the installation instructions should be protected with a type B RCD which raises the question why fit a RCBO in the unit?
So be it an inverter drive washing machine, fridge, freezer, or an EV there are items today which SOME claim stop the RCD tripping, yet others claim there is no problem, so the big question is if this equipment is used, is there a potential danger?
With a TN supply the RCD is an extra, we don't rely on the RCD, so no problem, where the problem arises is with a TT supply, if the RCD is frozen due to DC then it is serious, personally I like the RCBO as it means each circuit is independent, but it also means best you can get is type A.
However for the EICR we are not selecting what is used, all we are reporting on is the condition, this is what the C stands for, it is not a safety report, although I think it should be, and it is not a report showing how it complies, again I would like to see the return of code 4, so assuming the installation complied when installed, all we are looking for is degrading and damage.
Yes I agree the EICR is very like the EIC and some clients (local council build control for example) want it completing as if it was an EIC, but question is if no earth required before 1966 then why is it required today? I am talking about where MR16 lights converted from ELV to LV and cables not changed.
If not attracting a code C2 in a 1950's house, why should it attract a code C2 in a 2020 house?
