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.

    I suppose that 643.8 applies. I test R.C.D.s by plugging a tester into a 13 Amp socket outlets sometimes, so I can not think of a reason that you can't test an R.C.B.O. at a light switch as long as any loads that may be connected are disconnected that may affect the test results.
