Is RCD needed at both ends of armour feed to outbuilding

I noticed that before I posted it lol, I do like to lace my posts with a double dose of hypocrisy! haha

I think i'm an excellent smeller, but even I ****ed that one.

Doesnt really work with the automatic edit..........p-i-s-s-e-d.

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

I had a NAPIT mcs assessor attempting to give me a non-conformity for not bonding the PV array frame to the MET on a system using an isolating transformer inverter.

Even back then, isolating transformer inverter should never have had the frame bonded unless it was an extraneous conductive part (not that the TL ones should have needed bonding either, but at least he would have been applying the guidance at the time correctly, even if the authors of the guide themselves had clearly stated that this sections was wrong and shouldn't be followed).... turned out he was a sodding gas fitter by trade.

In contrast my last napit assessor was alright.

Yeah my napit assessor is a spark and to be fair he knows his stuff and generally asks me some good questions which I always have to go and pull my regs book from its holster. But this earth rod thing just got me thinking why? Surely taking a earth from met is going to create a major increase to the pfc via a additional parallel path or am I totally wrong here

Is not going, this iPhone is getting slammed a tell ya

Just noticed that this thread on RCD's is 6 pages long? What does that tell you about posters knowledge of the regs?? It would have been quicker to pick up a regs book and read it yourselves.

Taking your later comment into account I added the 'Not' for you,

Even if it did increase the PFC somewhat, it would still likely not increase the PFC above the 16kA conditional rating of the CU in domestic (Annexe ZA), unless you were right next to the sub-station lol


And to the other poster, there is not 6 pages about RCDs, if you care to have a read, a bit of confusion maybe lol, but not about RCDs.
