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

[Bul]

May be a silly question but are rcbo's tested the same way as RCD's?

 

[buzzlightyear]

what do you think !

 

[buzzlightyear]

you treat it has MCB but not MCB but RCBO.

 

[The Ghost]

Yes same way.

 

[Bul]

Yes same way.

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

Not really an RCBO is an RCD with overcurrent protection.

which test sheets.

If you read the manufacturers leaflet that comes with them some require you to remove the earth fly lead prior to testing. i do it as a matter of course and have not actually checked to see if it affects results. I know with some it can affect loop impedance tests.
Have seen many a CU with them cut off mind!

My test sheets will allow you to pick and choose whatever device your using (not aiming this at you buzz).

Why do you ask?

The 'function earth lead', does just that I believe. Cut it orrffh or not connect it might cause some functional problems. The earth & neutral fly leads have to be disconnected, if the manufactures state this, during IR testing, as far as I'm aware?

Obviously,MI should be adhered to,if you are writing down the test and result,but you could not damage any RCBO,using standard,IR test gear.

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..

*Bit drunk and can't recall whether it's 009 or 008!

yep , or is it 0010 nuwkie browns.

I was just thinking about a CU that only has rcbo's in it. Would each circuit be tested as an rcd. I've just never came across it and wanted to put it out for discussion.

BS EN61009 RCBO

yes is the answer.

 

[buzzlightyear]

do you know how to test the RCBOs.

 

[Octopus]

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.
