Electrical
Wire Gauge Calculator
Determines the minimum copper wire gauge (AWG) needed to limit voltage drop in an electrical run. Ideal for electricians, solar installers, and DIYers sizing cables for long runs.
Electrical Home
Wire Size Calculator
Find the correct wire gauge for any electrical circuit based on current load, run length, and allowable voltage drop. Use this when wiring outlets, appliances, or sub-panels to avoid overheating and energy loss.
