UNSPSC 39121325: Electrical operator interface unit enclosure

UNSPSC 39121325 Electrical operator interface unit enclosure is a Commodity code describing enclosures and interface hardware for electrical control systems at utility and municipal facilities. State and local governments procure these components as part of water and wastewater system upgrades, substation modernizations, and pump station automation projects. The work spans fabrication of custom control panel enclosures rated for specific voltage and amperage configurations, integration of circuit breaker assemblies and protective relay housings, and installation of operator interface hardware within larger electrical systems. Issuing bodies include utility authorities (water and wastewater), county public works departments, school districts, state correctional facilities, and city and county purchasing offices. Kissimmee Utility Authority, Hillsborough County, Broward County, and city-level community development departments appear as repeat or related buyers seeking electrical control system work.

Recent opportunities reflect activity across Florida, Michigan, Mississippi, Texas, Wisconsin, Georgia, and Virginia. The Kissimmee Utility Authority issued IFB 17-003-CV in October 2026 for 15 kV circuit breaker replacement and installation work at Marydia Substation, with two bidders competing at lump sums near $75,000–$77,000 and a mandatory pre-bid meeting held in October 2016. Hillsborough County Board of County Commissioners advertised ITB-26-00393 in August 2026 for pump station control panels and other enclosures across a two-year estimated value of $3.66 million, requiring UL 508A certification and factory acceptance testing; ten contractors bid, with unit prices ranging from approximately $21,000 to $112,000 per panel depending on configuration. Broward County solicited fabrication and refurbishment of water and wastewater control panels on an open-end, indefinite-quantity basis with responses due June 2026, requiring Florida Certified Electrical Contractor or Broward County Master Electrical Contractor licensure and 24/7 emergency response capability. The City of Bartow, Florida sought proposals for a new Master Lift Station Motor Control Center installation including MCC sections, VFDs, starters, and SCADA electrical connections. Fairfax County, Virginia issued a five-year term contract IFB for switchgear testing and preventative maintenance across eight facilities, requiring 10+ years' experience with high-current test sets and Virginia Master Electrician licensure on staff.
