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.

    If the circuit has high earth leakage then the R.C.B.O. would be tripping off at regular intervals so would no doubt be reported pronto. Why not just test the R.C.B.O. with the Test button? 643.8.
