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?

  • One could say, in some respects then,that testing at the remote end of a circuit has the advantage of potentially  revealing other faults and thereby improving the integrity of the circuit.



    Any such problems that might affect the safety of thr circuit should have already been detected by previous tests (insulation resistance and c.p.c. continuity) before you start doing any live tests such as RCD tests.
