Wire Size Calculator

Understanding Wire Size Calculation

Proper wire sizing is crucial for electrical safety and efficiency. The calculator helps determine the minimum wire size needed based on:

  • Current carrying capacity (ampacity)
  • Voltage drop over distance
  • Conductor material properties

Why Wire Size Matters

Using the correct wire size prevents:

  • Overheating and fire hazards
  • Excessive voltage drop
  • Energy waste and inefficiency
