EICR question, OLD AC RCD- code 3 or no code?

[J Sparks]

Definitely no code, regs are not retrospective.

Nonsense, try reading them.

I’m sure it says on page 1 that they’re not retrospective.

And if you search the forum for “not retrospective” you will find a good number of posts by different members all saying the same.

BS7671 is not retrospective (from memory page 4 states that) , however we do code the the current edition of the regs as stated in GN3.
to answer the question you have to assess the risk ,if only pure resistive loads are on an AC rcd no code or maybe fyi only, i would code C3 if other loads are present that don’t affect the testing of the (RCD) Residual Current Device at time of test,C2 if it causes rcd blinding and it does not function correctly.

I hate the description of the Regulations "not being retrospective". No such comment is made within the Note from the HSE. What it actually states is that compliance with previous iterations of the Regulations may not necessarily imply that the installation is now unsafe or that it requires upgrading. As such, it also doesn't rule out that aspects of it might actually be unsafe or require upgrading.

Looking at a MEM A100HE RCD earlier today (of which I've fitted many dozens over the years), and was surprised to see it caries the type A (sine wave over half sine wave) markings.
How long have type A RCDs been around? I assumed it was a relatively new thing.
This was a newer grey one, but I've looked at an older yellow one, and still the same markings.

I came across an old wylex one not long ago, and was also surprised that it was an A, and not AC

Most of the old Memshield 2 pods are type A.

We found a old MK LN range RCBO which has a Type A trip and a BS 3871 trip curve
