Duplex Pump Control Panel Development

Project Title: Electrical Engineer – Design of Universal Duplex Pump Control Panel Project Overview: We are developing a standardized duplex pump control panel to be sold as a commercial product worldwide. The goal is to finalize professional electrical engineering drawings, schematics, and a build-ready package for a compact control panel that operates two 3-phase pumps up to 25HP. The panel must be designed as a universal platform that can operate at 208/230V or 460V using simple component changes (conversion kits), without redesigning the control system. This is a product-development project, not a one-time building job. ⸻ Scope of Work The electrical engineer will be responsible for producing a complete construction-ready design package based on provided specifications, including: 1. Electrical Design and Drawings • Single line diagram • Power schematic • Control ladder diagram • Terminal strip layout • Door device layout • Internal component layout for a 30” x 24” x 10” enclosure 2. Bill of Materials • Detailed BOM with manufacturer part numbers • Two configurations: • Initial 230V configuration • 460V conversion kit configuration 3. Logic Implementation • Implement provided operating logic: • OFF / HAND / AUTO modes • Lead/Lag alternation • Remote RUN ENABLE input • Failover on overload • Phase loss and reversal protection • Anti-short-cycle timing 4. Product Standardization • Design must be reusable and repeatable • Support NEMA 1, NEMA 3R, and NEMA 4 enclosure options • Use IEC components for compact footprint • Ensure design fits within 30x24x10 enclosure 5. Compliance and Documentation • Design suitable for UL508A panel shop construction • Wiring standards and labeling plan • Installation and startup documentation outline ⸻ Design Requirements (Summary) • Two pumps, up to 25HP each • Three-phase operation • Convertible between 230V and 460V • Rotary fused disconnect • IEC contactors and electronic overloads • Phase monitor relay • Multi-tap control transformer (208/240/480 → 120V) • HOA selector and indicator lights • Dry contact BMS interface: • RUN ENABLE input • Pump 1 status • Pump 2 status • Common alarm ⸻ Deliverables Required • Complete schematic package in PDF and editable format • BOM with part numbers and quantities • Panel layout drawings • Terminal maps • Conversion kit documentation • Files ready for a UL508A panel shop to build ⸻ Candidate Requirements • Licensed or experienced electrical engineer • Experience designing industrial control panels • Knowledge of UL508A standards • Familiarity with IEC motor controls • Ability to produce professional schematics ⸻ How to Apply Please respond with: • Examples of similar control panel designs • Estimated timeline • Estimated cost • Software you will use (AutoCAD Electrical, EPLAN, etc.) This is the first version of a commercial product line, with potential for ongoing revisions and future projects.
