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.

  • Just gone 9.00 pm on a Sunday evening I have finished filing this weeks minor works certificates having been doing the relevant invoices and emailing them along with scanned copies of the MWC.


    So before turning my desktop off I had a look at one of the YouTube video links posted by Zoomup and it rolled onto another one about changing a light switch.


    I cannot image the consumer unit was opened for testing and actually I didn't notice any testers being taken into the building to do any testing at all, but the chances of the installed replacement switch being dangerous must be virtually nil as no shock risk is likely.
