hi all,

Failed my AM2 on IR test.
Just a query do you have to remove both the nuetral and the cpc fly lead from RCBO when doing a global test? I did this but I did not put the cpc from the ring final in to the MET bar. I tested the ring circuit, motor and strappers separately. That’s the only thing I didn’t do. Would this be a fail?
 
my understanding of the fly leads on rcbos is that the fly lead should be removed prior to a IR test unless the manufacturers paperwork that come with them say its okay to do with it connected. Having said that I have oftne tested with it connected with no noticeable impact. In a exam though its by the book. Some of the newer rcbos no longer have the fly lead.
 
Yeah, I removed the fly leads completely. I just missed putting the cpc from the disconnected ring final from the RCBO. Like I say the only thing I can think I didn’t do. Silly thing to miss and fail on. Get it the next time
 
Why would you disconnect the cpc any way that is not connected into the rcbo just take out the line and neutrals and remove fly leads and sorted i would say.

It is stated all cpc need to be connected when testing ir so dont remove any cpc at all
