## What is Wire Gauge & Size Calculator?

Wire Gauge Calculator

Find the minimum safe wire size in seconds. Enter voltage (V), current (A), run length (ft/m), and allowable voltage drop (%) — the app returns the smallest conductor that satisfies both voltage drop and ampacity, and shows you which one set the size.

New in this version
• IEC (mm²) sizing — now alongside NEC (AWG/kcmil); switch standards in one tap
• Ampacity check — sizes by current-carrying capacity, not just voltage drop
• More accurate AC — power factor, conductor temperature, and reactance
• Continuous load (125%), insulation rating, and installation-method options

Features
• Results in AWG/kcmil, inch, mm, and sq.mm at a glance
• Conductor materials: Copper, Aluminum & Steel
• Multiple parallel conductors per phase
• DC, AC single-phase, and three-phase (3- & 4-wire)
• Quick-pick common supply voltages + shareable results

Perfect for
• Low-voltage DC — automotive, RV, solar
• Residential AC — single-phase 120 V / 230 V
• Industrial three-phase — 480 V (US) / 400 V (EU)
• Long-distance power runs

Always verify results against your local electrical code.
