Is RCD needed at both ends of armour feed to outbuilding

[wersolaruk]

Never said I would have a rcd at both ends, either a mains switch at mains with a local rcd in garage or rcd at mains with main switch in garage. So there would only ever be one rcd. Am no fool so please don't make out or judge my competence engineer54 I several years experience from bms, hvac inverter drives, trend plc programming from running a 56 flat domestic installation. I am no dummy but far from the best and always look to learn more

No one is questioning your competence mate, just that of the OP's

That's not what the question posted said:

If you had two 30mA RCDs at each end of your sub-main, there is no guarantee which one would trip first, or even both would trip together, this means they won't discriminate with each other.

I usually prefer to have the RCD local (in the out building), as it is more convenient to re-set if it trips, instead of having to walk (possibly in darkness) some distance away to re-set.

Really makes you wonder doesn't it, and this is after 2 years of practicing on paying customers installations!! Another example of why there is no such thing as a Domestic Installer!!

Oops to my many Stella , I usually take it out on the wife

I was just stating that a napit assessor had told me to when doing a garage or outbuilding installation u had to use a earth rod for the earth in the garage, I would of normally brought a 3core swa across and used a core for the earth. I just gave a brief description of how I would of done the job, then all hell broke loose

 

[spark 68]

Well it proved both NIC and Napit talk ballocks lol, no doubt Elecsa do too!

I don't think I have ever asked them a question, most stuff I do is not part P anyway, I only keep it on for when my usual stuff goes quiet, so long as it pays for itself I keep it going, into my 4th year now, and with it being watered down recently it nearly didn't get renewed this year at all.

If my assessor pulled me up on a job like this I would hand him the regs book and the pile of GNs and tell him to explain to me where I had done anything wrong, I would like to bet him next years fees he couldn't lol
