Oh thats easy, what you need to do is.............

Try and be a bit more specific and people maybe able to help!!!
 
What happened? Please describe your method.
If it/they are fried after a 1/2 test then they should be replaced free of charge so not too much to worry about

As above.
What "first test", exactly?
And how have they failed? ie what don't they do now that they should do if working properly?
 
See the first line of my first post mate.
Describe what happened step by step and then we may be able to advise you

What test(s) have you done with them connected? Insulation resistance testing might well have "fried" them.
 
I remember an incident like this: press the trip button, reset the RCBO only half way so that the load kicked in and the it made a bang and thenRCBO was ****ed. That was an RS own brand. I remember we were betting that a RCBO would never fail, but it did.

Should still survive up to 6KV Icn (in theory). Perhaps he's invented some devious new device for us all to use. A RCBO with overvoltage protection as well ;)

Edit: Not funny then :(

Bit strange that all four failed with the test. Was it the insulation test, perhaps?
If you push it really, you can wreck anythingmif you just try hardmenough. But surely, an RCBO should survive the standard test procedures, unless it is a fake China import.

There are quite specific instructions supplied with RCBO's regarding testing. IR testing them is not recommended :)

Could you be a little more descriptive of 'fried'? Or perhaps they've been sautéed...
