Specification

250/3 Heavy Duty W/GRND THW Submersible Pump Cable - Copper 600V

Allowable Ampacity:

• 255 Amps (based on NEC guidelines for THW conductors in wet locations)

Applications:

This submersible pump cable is designed for continuous submersion in deep wells, industrial water systems, and large-scale irrigation setups. It supplies power from the control panel to single-phase 230V submersible pumps and operates at 600 volts with a temperature rating of 60°C (140°F) in wet conditions.

Size 250/3 Usage: This well pump wire is suitable for 3-wire high-capacity deep well submersible pumps that require a control box. It provides separate conductors for the run and start windings, making it ideal for municipal water supply, large agricultural irrigation systems, and heavy-duty industrial applications. Commonly used for submersible pump motors up to 50 HP.
