Typical 1 HP submersible well pumps draw about 10 amps at 240V. Larger 1.5-2 HP pumps may need a 30A circuit.
| Recommended wire | 12/2 with ground (UF-B for direct burial) |
| Breaker | 20A double-pole |
| Voltage | 240V |
| Typical amperage | 10A |
| Circuit amperage | 20A |
| NEC reference | NEC 430 |
| Max recommended distance | 200 feet (without voltage drop concerns) |
Wire must be rated for direct burial (UF-B) or run in conduit underground. For deep wells with long wire runs, consider upsizing to reduce voltage drop.
