Guess you can back-up this statement with some facts.

To any thinking person, it should be quite obvious why Sonthi will say nothing on this matter.

Ok, thanks for the info. I'll sleep a bit easier knowing that they (RCBO's) function and not just there for decoration.

Thanks for the info on the volt meter, I didn't even consider the low current draw across the multimeter - the RCBO's are seperate units on each of  the power circuits.
Would a 15 watt test lamp work ok to test L to E to ensure the RCBO's  function.

Please clarify some confusion on my part, my house wiring system has just been completed. I'm afraid I don't really trust the sparkie to have done the right thing thru-out the complete system so have started a check of my own - first thing I noticed and which is contrary to good practice and completely against what I instructed was " no twisted and taped wire connections" looked at 2 power outlets that I knew would have problems if there was to be a problem - and yes - twisted and taped connection - this is also a problem on some of the light fiitings.
Of course this is enough for me to say to the builder "not acceptable - the wiring is not as I wanted nore is it correct - get it fixed" - final payment is now being negotiated.

Secondly, RCBO's and the confusion,using my multimeter - from L to N I read full voltage - from L to E I also read full voltage and the RCBO doesn't trip  - I expect the RCBO to trip as I assume the L to E is what we are supposed to be monitoring. I haven't established as yet if the N and E are connected,  the earths are supposedly all connected outside of the switchboard somewhere so can't easily check this out or see if E and N is connected anywhere.

Any comments welcomed on the RCBO (my confusion)
