About this calculator
Overview
This general-purpose calculator determined the required wire gauge for any electrical load, ensuring it meets both ampacity and voltage drop requirements.
💡
Pro Tips
Residential circuits commonly use copper.
Large service feeds often use aluminum to save weight and cost.
Voltage drop should be under 3% for most applications.

Fun Facts
"Electrical resistance generates heat; if a wire is too thin for the current, the insulation can melt."
"American Wire Gauge (AWG) numbers get smaller as the wire gets thicker."
"Superconductors have zero resistance but currently require extreme cold."
