RCD cop-out

[kingeri]

Was talking with a fellow spark (young chap) tonight and he was telling me about many times he couldn't achieve satisfactory Zs so he just doesn't bother cos the circuit is RCD protected. I said that the RCD is a secondary line of defense....the MCB should still bloody work (in fact it should trip first in most cases). I think some folks are using the RCD as a cop-out.....poor old MCBs / fuses. mg_smile:

Was he talking about circuits he'd installed himself. If so then he obviously needs to learn how to design circuits properly :cowboy:

That is a worry...

What's the betting he's one of these new 17 day herbert's or at best a Electrical Trainee boy!!

But this is a growing phenomenon with RCD devices, they are being relied on far too much these days, as the miracle cure-all device. Any electrician worth his sort will have a working proven ADS in place, before turning his attention to his supplementary protection devices....

He's the type who only sees the regs that he understands.
