Mv Cable Sizing [exclusive] -

This reveals that ampacity, not fault rating, often drives MV cable sizing in congested installations.

In MV systems with high fault levels (above 31.5 kA), conductor spacing and clamping must resist magnetic repulsion forces. For standard trefoil formation, this rarely governs size but influences cable construction (round vs. sector-shaped conductors). mv cable sizing
