From my understanding the six monthly test of the "Test" button is actually a "User" check. Now many on here will start saying cant have unskilled people accessing switch rooms and start pressing buttons that could affect sensitive supplies and cause more say production or financial issues.

But thats down to the Duty Holder to determine along with the helpful advice of an electrical practitioner.

So if somebody has been shown how to press the test button and the RCD/RCBO "Trips" to the off position then thats it, job done.

My understanding is all positive successful tests dont need to be recorded, it is only the RCD/RCBO units that failed to trip that would then be recorded, and unique company procedure would be to then call in a maintenance technician/electrical contractor to do some further investigation and likley use of a RCD tester.

I personally dont think it warrants comment or certainly a coded comment on a EICR. As long as the appropriate BS7671 label is present indicating Button pressed etc etc then thats compliant, A good contractor/inspector could have a conversation to ask perhaps because they can tell the six monthly test isnt being carried out, he has that conversation or sends a letter/report indicating buttons should be tested.

Of course if there is a simple log book/file same as testing the fire alarm weekly, that who, when, date, time the test was acrried out  and a signature then to me thats it, they could write "All Ok" and only ever then add what unit failed to work, and that then is followed up to persons who can action a electrically skileld person to further investigate.

I wouldnt code the button test isnt being carried out on a EICR.

If during a EICR the electrical inspector found a RCD/RCBO not working of course thats coded I would say a C2, if label for six monthly test missing a C3.

For a point of interest to people in my area of work on filling stations in our technical publications the test button on RCD/RCBO's should be pressed Monthly!! for all Haz area circuits simply because of the greater risk. So that means we have a modified BS7671 RCD Test button label applied that says monthly test not six months.

Frequency of formal testing during an EICR, unless the manufacturer of the RCD/RCBO stated in their instructions a more frequent pressing of the button or indeed formal RCD tests then thats what should be programmed in by Duty Holder and their electrical inspector/contractor.

BS7671 indicates the designer dictates frequency to the first EICR and thereafter its the actual electrical inspector carrying out the EICR that dictates the period to the next inspection.

Yes there are guidance documents and suggestions out there that indicate 3, 5 or whatever years, but its only guidance, so a high risk, wet  industry application with lots of unskilled people using electrical equipment, machinery, I would want frequency perhaps sooner than guidance indicates. Also age of the installation, would affect duration/frequency of EICR as a newer installation could in theory go longer between inspections than a 30 year old installation, but again thats something the EICR inspector should be taking into account when they make reccomendation to next EICR inspection.

My view is that the installation should be inspected and tested for compliance with the current edition of BS 7671. Any defects or non-compliance discovered should be recorded and Coded.

If the RCD is not of the correct type, fault current rating, does not meet the requirements for selectivity, or other BS 7671 requirement and does not meet the disconnection time when tested with and instrument or does not work on the user test device then that should be recorded and coded. 

It is irrelevant if the user is not testing it in accordance with the manufacturers instructions or the requirements of BS 7671. That said RCDs should be user tested and a record kept in industrial, business premises or premises where the public is admitted or people work whether paid or not.

If requested I could post my views on coding of RCD compliance?

Morning John,

"If the RCD is not of the correct type, fault current rating, does not meet the requirements for selectivity, or other BS 7671 requirement and does not meet the disconnection time when tested with and instrument or does not work on the user test device then that should be recorded and coded."

In my reply I agreed with what you said, wrong type, current rating , selectivity or doesnt disconnect in time while being checked during a EICR inspection, without any doubt is coded appropriately to me a C2, If six monthly test label for the button test is missing I would code a C3.

But why would a "User Test" be coded as you listed in your comments? I agree the actual six monthly or less user test of the buttons should be recorded and made availible by interested parties. But a "User" isnt going to Code anything, they are not doing the EICR, thats the point Im making, and as such the person carrying out a EICR shouldnt code that the six monthly test isnt been done by the user, it doesnt have a place on a EICR, but a competent inspector would in writing back to the Duty Holder highlight that requirement.

So for example, I press all the RCD test buttons on my dist boards here at home and one fails the test button test, of course I would then use my RCD tester to check it or indeed replace it, but I dont record any C code on anything as Im not doing the EICR on my installation when I test the button, I actually get my installation at home inspected every five years by local SELECT contractor not 10 years for a domestic dwelling as per GN3 (Thats my Choice). Before you say its not a place of work my home? The small print of my home insurance dictates that the electrical installation must have a periodic EICR carried out, I also thru choice given I have client meetings here at my home based office and me being pedantic, see th ring main where clients plug in laptops etc as being "A place of Work". 

The Test button check is aimed at the occupier/Duty Holder of the property, not necassarily a electrically skilled or trained person. As I mentioned, on a filling station where we can have over a 100 RCD/RCBO's and our technical requirement for a Monthly Check of the test button as we overule the BS7671 Six month period because of safety concerns for the flammable atmospheres and public using fuel dispensers. Its the retailers staff that check the test buttons, they only log and call if one doesnt work, or that is the plan anyway.

But why would a "User Test" be coded as you listed in your comments?

I suspect you and JP are at cross purposes with the words and are actually in agreement. I think JP actually said "the user test device" rather than "user test" - i.e. he was referring to the T button - operation of which should be checked as part of ordinary BS 7671 RCD testing (col 29 of the schedule of test results).
