:) I know sounds silly, and its clutching at straws but everything was in the place was on a spd extension leads.
I didn't pay too much attention at the time but he did mentioned that the mcb for the rfc tripped once when he was reset the RCD while carrying out the auto test.
We unplugged...
I looked after it, test leads always coiled up nice after each use too..
The only thing I can thing of is prior to this I got my trainee to carry out a RCD test at a property that had loads of surge protected extensions leads. He left them plugged in along with other stuff when doing the auto...
My Dilog DL9118 died in the middle of an EICR on Friday.
Shows a continuity reading of 0.24 on low ohms even with test leads disconected.
Lasted around 2years :(
Had to pop to CEF ended up getting the Megger 1941+ with the new EV adapter. Didn't really want to pay that much. Fingers crossed it...
Bsi have now released A2 in pdf format.
Still split up into sections but definitely easier to read.

As above Wylex is the best option!
Proteus do one but its cr@p has old AC type RCCBs so its not really reccomended either.
I had to sort one out the other day.
Think it was in the thread about pulling DNO fuses.
I'll see if I can link to the thread...
For those that are interested ammendment 2 got released earlier today..

From a quick glance it looks like we will be installing AFDDs for AC final sockets and final circuits upto 32amps with the exception of some safety...
I think your right! I did see a snippet of A2 (which is due to go to DPC soon) which Sparkninja put on his instagram, I expect you saw it too!
The wording was something along the lines of,"Type AC rcds can only be used to serve fixed equipment, where it is known the load contains no DC...
I recently was called out to look at a possible rewiring job, The customer had someone in to do some work in the bathroom (6 months prior) as part of that work they changed to consumer unit and put an Earth stake in.
Anyway the consumer unit was a mess, you could tell the previous electrician...
It is acceptable for the SPD to be installed in parallel to the intake, the combined lengths of conductors connecting the SPD should be less than 1meter this is to keep resistance and inductance as low as possible, the Bema guide states that its good practice to twist or cable tie the conductors...
Were you sponsored by someone like the JTL when you did your apprenticeship? You might be able to contact them?
When you speak to the ECS its like speaking to the Little Britain character, the one who said, "The computer said no".
C&G do this alot especially in multiply choice papers, although the wording they use is generally "maximum volt drop" I believe they just do it to check the candidates knows how to apply basic correction values, as they always give both answers.
Another one they like to check is that the...
Let the other person crack on, i think you were a little cheap, its alright if you can get in and out, but its very rare in these larger jobs. there's always a few niggles to get around on the second fix so id be looking at around £16,000 at least.
IMO the statement about SPDs in the regs could be clearer.
How do you justify that?
A small SPD CU can be purchased for around £50, a more expensive Wylex main Isolator with SPD can be purchased from TLC for £140 labour costs for a mornings work is approx £150, So if you work on the generous...
I'd be about £1750, if it were a particularly easy job I might go as low as £1500. Did you say you quoted £1250 I think that is very cheap especially with two cooker circuits.
NAPIT aren't suggesting that you code no RCD protection o lighting circuits a C2?
Quote from the Codebreaker book.
"Circuit supplying luminaires in a domestic dwelling,class 1 fittings, No 30mA RCD protection C3.
