This wire gauge calculator helps you determine the appropriate wire size for your electrical projects. It calculates important parameters like wire diameter, cross-sectional area, resistance, voltage drop, and current capacity based on the selected wire gauge and other parameters.
Features:
- Calculate properties for both AWG (American Wire Gauge) and SWG (Standard Wire Gauge)
- Determine voltage drop based on wire length, gauge, and current
- Calculate maximum current capacity for different wire gauges
- Support for both copper and aluminum conductors
- Recommendations based on voltage drop percentage
Why Wire Gauge Matters:
Selecting the correct wire gauge is crucial for electrical safety and efficiency:
- Undersized wires can overheat, causing fire hazards
- Excessive voltage drop can damage electrical equipment
- Proper wire sizing ensures energy efficiency and reduces power waste
- Correct wire selection can prevent nuisance tripping of circuit breakers
Common Applications:
- Residential and commercial electrical wiring
- Automotive electrical systems
- Solar power installations
- Battery bank connections
- Audio and speaker wiring
- Low voltage lighting systems
