The power cables will be concrete encased and approx 10'-15' below some rooms that could have some sensitive digital equipment. Someone on another forum recommended running them in steel conduit and grounding the conduit that would provide some shielding.

Well someone has brought up the concern of EMI issues with the installation. The setup involves 8 parallel conductors for each phase both carrying approx. 345A all at a frequency of 60Hz. Someone has suggested twisting the wires to reduce EMI radiation, but I tend to think this won't have a...

If you have a 3 phase 4 wire distribution where the 3 phase conductors and 1 neutral is inside a pvc conduit, how would you model the force of the electromagnetic field at a certain distance away from the conduit? Assuming the loads are balanced, the currents would sum to zero on the...
