TESTING AN RCBO AT A LIGHT SWITCH

I asked this question some time ago, but during the site changeover I somehow got locked out.

So I would like to ask again.


Is it acceptable, using a two-wire RCBO tester (Megger RCDT320), to test at a light switch using the phase and earth wires?

If it is acceptable are there any disadvantages?

Regards,

Mike.

    If you are just replacing a broken light switch are you really going to dismantle the consumer unit for testing?

    Does not the 'scope' section of the notes for the person producing the [minor works] certificate,  in Guidance Note 3 (pg 130), suggest that the answer is yes? I also know one trade body says that although a MWC need not need completed for replacements, relevant testing pertaining to the certificate must me carried out [which would include RCD testing], noted in writing, and given to the relevant person.
