Wire Ampacity Calculator
Calculate the safe current-carrying capacity of electrical wires based on wire size and type.
Understanding Wire Ampacity
Wire ampacity refers to the maximum amount of electrical current a wire can safely carry continuously without exceeding its temperature rating. This is crucial for:
- Preventing electrical fires
- Maintaining system efficiency
- Ensuring code compliance
- Extending wire lifespan
Factors Affecting Wire Ampacity
Several factors influence a wire's ampacity:
- Wire size (AWG rating)
- Conductor material (copper vs. aluminum)
- Insulation temperature rating
- Ambient temperature
- Number of current-carrying conductors
Safety Considerations
Always consult local electrical codes and a licensed electrician before making any electrical installations. This calculator provides general guidance but may not account for all installation-specific factors.
