Recommended Wire Size and Breaker Table
The following table shows standard wire sizes and corresponding breaker ratings for typical EV chargers. This reference is helpful to quickly compare the results from the calculator with common setups:
| Charger Amperage (A) | Wire Gauge (AWG) | Breaker Size (A) | Voltage (V) | Continuous Load % |
|---|---|---|---|---|
| 16 | 12 | 20 | 240 | 80% |
| 24 | 10 | 30 | 240 | 80% |
| 32 | 8 | 40 | 240 | 80% |
| 40 | 6 | 50 | 240 | 80% |
| 48 | 6 | 60 | 240 | 80% |
This table highlights how different amperages require specific wire sizes and breaker capacities. Using a wire smaller than recommended can overheat and damage the insulation, while an oversized wire increases costs without additional benefits.
