Start with the pump duty
A three-phase pump panel is defined by the pump curve, motor data, starting method, duty/standby logic, instrumentation, and site power. “Three-phase” identifies the supply arrangement but does not determine the correct starter, protection, or enclosure.
Inputs for selection
| Input | Why it matters |
|---|---|
| Motor nameplate and pump duty | Establishes current, starting, and operating requirements |
| Starter, VFD, or soft starter | Matches the process and starting method |
| Duty/standby sequence | Defines alternation, lead/lag, and failure response |
| Level, pressure, and flow signals | Provides automatic control and alarms |
| Incoming power and fault data | Supports protection and coordination checks |
| Site environment and cable entry | Determines enclosure, cooling, access, and routing |
Documentation and scope boundary
Request the pump schedule, motor data, sequence narrative, I/O list, alarm matrix, layout, cable entry, drawings, and commissioning responsibilities. This article does not size a breaker, guarantee flow, or replace a pump-system study.
