Do I extend the PME outside to a Log Cabin style building??

[MATTMOUSE]

Please forgive me in asking this same question which normally results in an arguement......lol

I friend of mine needs to have a supply installed (a lighting circuit, a heater circuit and a socket circuit) in a SWISS style log cabin located about 2 metres away from their main home which has a PME system.
The BIG question, Can I used the PME to supply the cabin?...........I wish to use either a 6mm or 10mm 3-core swa for the supply cable, RCD protected of course.

Sorry for this post, just wanted a few thoughts on this particular installation.

A huge thanx for any thoughts guys!!

They cant export the immagrants in the uk, PME dont make me laugh

Have we been here before once or twice?:ack2:

 

[telectrix]

maybe if they made PME illegal, then we could'nt export it....

I can sell you some PME Lites from belguim for 5 euros!

Thanx "Rockingit"..............So if theres no ext' metal parts that need "Bonding" in the cabin, then there's no need for the 10mm Equi bonding conductor.............could we not then rely on the 6mm swa 3rd core as the cpc supplying the cabin??............just a thought......lol

Yes, .....But!! If during installation the PVC sheath is damaged, then moisture ingress to the SWA can corrode the SWA in a relatively short time, ...time depending on the chemical make up of the soil it's buried in. I would always advise on using 3 core SWA, the cost difference is minimal, and your assured of a good CPC connection to earth when all connected correctly!!! It's a no brainer in my opinion!! ...lol!!

Respect to you guys for the info!!!.............is there a limit on how many seperate buildings (sheds, cabins etc) that you can use from one PME source?...........i heard that if lets say you have three sheds in your garden, you can only share or use the PME source from your main property for one shed and the other two must have a TT system.
Sorry to be a Parrot and repeat myself...........We can safely say that I can supply this cabin using the swa cpc and armouring (connected to the property PME MET) as the cabins incomming earth to feed various circuits (lighting and perhaps a small panel heater)

Where have you heard it?...I'd try reading 7671 instead.

I tryed reading a 7671 but it was flying past to quick!

Do it properly -make it a TT system
Run SUPPLY from the house distribution board to a new small distribution board in cabin with 2.5mm SWA
New, small distribution board in cabin will require a 30ma RCD for protection
Put a rod in the ground outside the cabin connecting to the dist' board with at least 16mm earth cable.
Put your feet up.

Tell me, ...Are you actually being serious here, you would honestly put in a TT system (and probably a p**s poor one) for this log cabin that's just 2 metres from the main house?? I suppose you would isolate and rod an outside socket outlet too!!!

Oh and please inform us all, exactly what a 16mm earth conductor is going to achieve for this TT system your proposing?? God help your PME customers is all i can say!!

amazing, truly amazing!!!

I was waiting for E54 to reply to this one
