An industrial installation requires a single-phase load current of 75 Amps . cable derating factor table

For underground installations, the soil’s ability to conduct heat away from the cable is critical. Standard tables assume a soil resistivity of 2.5 K·m/W (typical for moist soil). If the soil is dry sand or rock, the derating factor can drop to 0.6–0.7, significantly reducing cable capacity. End of Technical Paper An industrial installation requires
