NIGP 28509: Cabinets, Electrical Service Entrance

NIGP 28509 Cabinets, Electrical Service Entrance is an Item code encompassing the procurement of electrical service entrance cabinets and related motor control centers that state and local governments buy for water treatment and distribution infrastructure, facility operations, and flood management systems. Recent solicitations show governments purchasing complete motor control center units for booster stations, medium voltage soft starters integrated with existing control systems, and variable frequency drives in NEMA-compliant enclosures — equipment that functions as part of larger electrical distribution and automation systems rather than standalone components. The code also captures fabrication and refurbishment services for custom-built water and wastewater control panels, including automatic transfer switch panels and remote telemetry unit panels that comply with National Electrical Code, NEMA standards, and local building codes. State and local issuing bodies include municipal water districts, county governments, school districts, and transit authorities, with Eastern Municipal Water District in Riverside County appearing as a repeat buyer across multiple recent procurements for booster station equipment upgrades.

Activity under this code concentrates in California and Florida, with recent opportunities spanning Riverside County municipal water infrastructure, Broward County water and wastewater systems, and school district operations in Texas. Representative recent solicitations include Eastern Municipal Water District's RFB 3957 for two Motor Control Centers at Antelope Booster and Olivas Booster facilities (due August 11, 2026, as an IFB with individual project evaluation and award), Broward County's open-end contract PNC2132148B3 for fabrication and refurbishment of water and wastewater control panels (RFP posted May 21, 2026, due June 22, 2026, with mandatory Florida Certified Electrical Contractor or Broward County Master Electrical Contractor licensing and 75 percent performance requirements), and Northside Independent School District's IFB 2026098 for electrical equipment, parts, supplies, rentals, repairs, and services (posted June 8, 2026, due July 1, 2026, replacing an expiring incumbent contract). Broward County's two control panel solicitations reflect longer-term framework contracting with estimated annual pass-through allowances of $38,000 to $80,000 for materials, equipment, permits, and specialty services.
