TESTING AN RCBO AT A LIGHT SWITCH

ietmgreen
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.

    Thanks  mapj1.

    No particular fault in mind.

    It just struck me that periodic testing Zs at the light switch is very convenient.

    So why not, for the extra minute or so, test the RCBO.

    Some colleagues have been adamant that RCBOs must be tested at the D.B.
