new rcd failure

[GLENNSPARK]

when I worked in BMS systems the service guy tested the outstation alarm by initiating it on the PC but this did not prove the actual input at the outstation he thought it was smart I thought it was lazy now you think when you return the RCD they would have a calibrated tester on hand but I dont think plus the majority of these are built in the far east so that tells me their QC is not very good plus it would bother me if someone got hurt because I saved £15 on a CU

and this one certainly wouldn`t hold up in a court either....should it go that way..

only use hager now.

although if cost isn't an issue.. merlin gerin seems the best

I wonder if you'd still feel the same if you saw the amount of Schneider (MG) RCDs of all types that got returned to the manufacturers on my last project?? I doubt it!! lol!! As i say, it doesn't seem to matter who or where these units are made, the reliability just isn't that, most think they are!!
