New Zealand New house supply from 3 phase next door

miner69er · Jun 24, 2013

Hi Everyone, i'm after some input...
New house been built and i need to install a mains cable from 100Amp 3 phase in unit next door (unit is part of the plot and just oversized garage)
Now.... i've never installed bigger than 6mm square for outbuildings etc. House is to be single phase only. Looking at the big green book, 25mm SWA 3 core should suffice with the cable being buried at the correct depth. But should i bury it in conduit or lay direct in the ground. And any other advice on the subject of laying the mains would be greatly appreciated.
