Cable Schedule Validator

NEC 310-based sanity checks on a cable schedule. Validates ampacity (NEC 310.16, 75°C Cu/Al), 125% continuous-load derate (NEC 210.19/215.2/430.22), 3% feeder voltage drop (NEC 215.2(A)(1) informational), and required field completeness.

Voltage drop uses 3-phase approximation: V_D = √3 · R · (L/1000) · I / N_sets.
