Hi all trying to build a house and not sure of the cable/wire size. its 200m from the box to the house and its?
for underground power and to go under a 2m creek. i will be installing a aircon and and outdoor spa, dishwasher and lighting and power for 7 rooms i also want to be able to run tools like mig welder and power tools. i was tolld to run three phase but not sure of size and amp and insulation. thanks for your help.
Get a licensed electrician to do this. Specially with the creek involved.
You need to calculate your power needs first, but it seems like you need somewhere in the 200-500 amps area.
500 amps three phase 208 is 170 amps per phase.
copper, you would need 00 for the current. But calculate the voltage drop for 660 feet, which comes to 26 volts, too high. To keep the voltage drop to 14 volts, still too high, you need 0000 wire, very expensive.
Given the very high cost of the wire, talk to the power company, and see if they can run a 6kV line to your house, and put a transformer nearby. This will avoid the high copper cost.
I can't find someone selling 4x0000 copper, my guess would b US$50 per foot.
