Low Voltage DC Wire Size Calculator
Low voltage DC wire size calculation is crucial for ensuring safety and efficiency in your electrical systems. Our calculator simplifies this process, helping you make informed decisions.
- Enter the voltage and current values.
- Select the conductor type.
- Click ‘Calculate’.
The calculator uses the following formula to determine the wire size:
Wire Gauge = (Current * 78.8) / (Voltage * Conductor Resistance)
Conductor Resistance is 1.68 for copper and 2.83 for aluminum.
| Current (A) | Copper Wire Gauge | Aluminum Wire Gauge |
|---|---|---|
| 10 | 14 | 16 |
| 20 | 12 | 14 |
| 30 | 10 | 12 |
- Always use the correct wire gauge to prevent overheating and fires.
- Consider using larger wires for long runs to minimize voltage drop.
- Regularly inspect your wiring to ensure it’s in good condition.
What happens if I use a wire that’s too small?
The wire can overheat, leading to melting, fires, and electrical shorts.
