I have a shed 30 meters from my house and i want to supply power to it (for 2 lights & 2 double power-points).
What size wire should I use, 4mm ? Also can a wire still be suspend or does it have to go underground.
Suspended the distance & wire length would be about 30 meters, if underground the length would increase (due to the path it would have to take) to between 35 to 40 meters.
