Is all the electrical add up about 6000 watts or so
75 square meters of cable diameter should be about 5mm. Cable (electriccable; powercable): usually consists of several or several groups of wires. Safety requirements: When the cables cross each other, the high voltage cable should be under the low voltage cable. If one of the cables is in the range of 1 m before and after the cross-pipe protection or partitioning, the minimum allowable distance is 0.25 m. When the cable is close to or intersecting the heat pipe, the minimum distance between parallel and cross is 0.5m and 0.25m, respectively. When the cable is crossed with the railway or road, the pipe should be protected from the rail or the road 2m. The distance between the cable and the foundation of the building shall be such that the cable is buried outside the building; the cable shall be pipe-protected and the protective pipe shall be outside the building. Directly buried in the ground between the cable and the grounding of the grounding device should be separated between 0.25 ~ 0.5m; buried directly in the underground cable buried depth, generally should not be less than 0.7m, and should be buried in the frozen soil layer.
4.9 or 5 bar 75 square meters? Too big, is it not 75 square millimeters?
