Hi,
I have a house with a standard mains supply coming down a pole in the front garden to a brick meter housing.
I also have a bungalow that is 350 metres away and is also supplied from my existing mains supply via an underground SWA cable (7 strand 1.1-1.4mm so 10A I think max) 50 metres past that is another building which is to be replaced by a new house.
I have ordered 2 new 5KVA supplies which will also come down the pole and terminate in 2 new utility cabinets which will house the meters on either side of the existing brick built one.
I then intend to run 2 x 16mm 2 core SWA cables underground to replace the old SWA cable to the bungalow and supply a new supply to the new house. The new house will have 5kw solar panels and possibly a Tesla powerwall and be very low energy requirements.
Couple of questions...
1) I intend to put earth spikes on each end of each cable connected to the armouring, is this ok?
2) Is there any reason I can't run the two cables in one 63mm dia twin duct? (I mean is there an issue with capacitance or something)
3) The cable run is across my own land, garden, field, driveway I assume I just use common sense approach as to cable depth and include tape above it?
4) Best place to buy the SWA cable from?
Regards
Jim
