How do you test RCBO's Same as RCD's

[KEV 1 N]

On the schedule of test results simply put 6100* instead of 60898/3036/etc etc. Obviously the x1 x5 results are on the far right hand side..

I was just thinking about a CU that only has rcbo's in it. Would each circuit be tested as an rcd.

yes is the answer.

do you know how to test the RCBOs.

You need to test the RCBO's before connecting the circuit ... Then take the Zs at the end of the circuit. Obviously you can't do global ir tests so ir tests on the circuit come before the Zs

Thank you so much for your help. Appreciated.

Actually I probably don't.

you treat the rcbo has a mcb but having a mcb you will have the tails going to the neutral bar from the circuit and the earth goes to earth and the line into the mcb.. on a rcbo the line and neutral goes in to the rcbo on the rcbo the fly lead neutral goes to the neutral bar & the fly lead earth white goes to the earthing bar with the earth from that circuit .

Many thanks, I've just never thought about it. Should test sheets then say RCD / RCBO tests?

Only if you ignore the definition of an RCD.

What you are referring to as an "RCD" is in fact an RCCB. It is just one of many types of RCD, which includes RCCBs; RCBOs; SRCDs; PRCDs etc.

Thanks for all your comments. I can see how obviously silly my question was. I respect the forum members opinion's and appreciate all advice.
