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

Voltage Drop Calculator

Computes the voltage drop across a wire run given current, one-way distance, wire gauge, and conductor material. Essential for ensuring devices receive adequate voltage at the end of long cable runs.
