UNSPSC 39121907: Receptacle Blockout

UNSPSC 39121907 Receptacle Blockout is a Commodity code that encompasses electrical control enclosures, junction boxes, and motor control centers (MCCs) serving water and wastewater infrastructure. State and local governments buy electrical equipment fabrication and replacement services under this code — specifically UL 508A-certified control panels, pump station enclosures, generator terminal junction boxes, remote terminal units, and complete MCC assemblies with integrated VFDs, starters, breaker assemblies, and SCADA electrical connections. The solicitations show work ranging from single-unit emergency MCC replacements to comprehensive multi-week fabrication contracts spanning electrical configurations from 3 HP to 75 HP across multiple voltage classes (480/277 volt 3-phase, 240/120 volt 3-phase, and 240/120 volt single-phase). Issuing bodies include county water and wastewater authorities, municipal utilities, special-purpose water districts, and school districts; county boards of commissioners and municipal wastewater departments appear repeatedly in recent opportunities.

Recent activity concentrates in Florida and California. Hillsborough County Board of County Commissioners issued ITB 26-00393 for pump station control panels and other enclosures with a two-year estimated value of $3.66 million, bids due September 29, 2026, requiring UL 508A certification and weekly fabrication capacity of two to four complete panels plus other enclosures with mandatory 24-hour emergency callout support at no additional cost.
