Frequently Asked Questions

What is acceptable voltage drop?
NEC recommends max 3% for branch circuits, 2% for feeders. Combined total should not exceed 5%.
Single vs three phase formula
Single phase: Vdrop = 2 × I × R × L. Three phase: Vdrop = √3 × I × R × L. Three-phase has lower drop for same load.
