Part P assessment question

[markadams]

One of the questions on a recent Part P assessment was how would I wire an external outbuilding if the earthing arrangement to the property was PME.

I said I would run a three core SWA from the property to the outbuilding and use the cable armour and the third core as the exported CPC.

I was highly criticised and was told that I should install a rod at the property and at the outbuilding.

I can find no mention of this in 17th ed AMD3 book, can anyone tell me where i would find this if it is the case.

I have had a couple of other Assessments previously where they have checked out building installs and never mentioned this so I am not happy.

Top result, well done. Let's hope your clown of an assessor is no longer assessing.

Might be better if he carries on assessing, now that he’s learnt something?

Agree. I'm in the habit of putting my reference books on the table in front of The Man, for just such learning opportunities .

Just spoken with them again and have been told that I am correct and it will be removed, what a joke.

Good news, bet the assessor guy can't even hold a screwdriver the right way up.

Worst assessment I ever had was with a stromer assessor, he couldn't stop telling me how good he was and then giving me incorrect information including that if an outbuilding in a garden was more than 10 metres from the house it had to have TT.

I got fed up with constantly having to chase stroma for every certificate I applied for (I complained to the stroma manager over the phone and in emails and nothing changed). The £4 extra a week I pay to the NICEIC is worth it to me.

Time to change assessment company methinks..

But i have to say, I'm with stroma for 2 years now and they've been fine. I guess it just depends who you get.. unless they've been told to get harsher..

Fixed that for you

There's a whole industry built up around
Taking money out of electricians pockets and these parasites seem to increase by the day .

That sounds like the Stroma assessor I had last year. He insisted that any outbuilding FURTHER than twenty metres from the main building needed to be TT.

To my mind it seems everybody is wrong
Firstly the assessor for calling it a non compliance of the wiring regs

Its wrong by the op (and everybody else here) for assuming this is a issue about those wiring reg being contravened or not

As far as I understand,there can be dangerous situations created by incorrect use of the supply earthing arrangement

Its a "suppliers" stipulation that Pme not be used outside of the equipotential zone without their permission

That permission should be sought from the supplier in order to do so,otherwise its get yourself a rod and provide your own

The wiring regs will tell you how to cater with whatever earthing is used,it does not give choices of what to do with the earthing provided by others and whether it should or should not be utilised

So no outside earthed lights without permission from the supplier?

If thats the case then the DNO should be providing that info when they install the supply or a upto date map online so the information can be cross referenced.
