Buying Guide
Power, enclosure, and wiring are the three pillars of selecting a submersible motor control box. Consider these practical questions:
- What is the horsepower and voltage of your well pump? Match the box to the exact motor rating for safe operation.
- Do you need indoor/outdoor protection? Enclosures with NEMA Encl. 3 ratings perform better in exposed environments.
