What advice can you give concerning running a 3 metre run of mains tails under ground from the meter head to a new CU in a newbuild property (barn conversion)? and what size would you say?
I'm assuming at this stage the earthing will be tncs.
The requirement is 100A and I see in the TLC catalog that 16mm 2-core is specced at 110A.. so could use 2 core with a separate 10mm/16mm earth? or best to go for 25mm 3-core? (big difference in price.. )
Ive used swa before but not in such a size.. or would it be a better option to use ordinary mains tails thru a metal duct?
The only problem I can see with a tube/ducting is to slow bend it upwards at each end and I guess you would still need to bond the tube but not to faff around with terminating it with conductive glands..
Cheers
