good idea. then you could use the cpc as a horizontal earth "rod"
 
think he's referring to the other thread about tearing sheath with cpc... another mountain out of a molehill thread.
 
especially with bike frames and Tesco trolleys added to the mix.
My age is showing Tel , I read it as canal board, I don't know where I got that from.

should have gone to specsavers. :p:p:p
 
As some if the others have said 4mm is not sufficient due to voltage drop. 6mm may just be ok if minimal sockets and lighting in cabin, otherwise 10mm.
 
Based on a similar job I have just calculated for 50 Meters. It was 10 mm SWA.

I don’t know your total load after diversity so cannot give you your definite sizing.

You will have to work it out on your figures.
 
he'll fight you on the beaches, on the streets and in the hills.
 
For volt drop on 4mm SWA over 50 meters you are looking at no more than 14A to get below 3%
 
The regs really need to bottom this. They put depths for other areas why don't they do it for domestic?
More to the point, why don't people use 600mm as specified in the regs.
