What medium-voltage equipment does a commercial facility use?
Large commercial facilities use service-entrance switchgear, distribution transformers, metering equipment, junction cabinets, secondary connectors, and grounding to take medium-voltage service and step it down to building distribution.
The six equipment categories on this page cover that scope. Each links to its full category page with the manufacturers Hawk carries for it.
What standards apply to commercial medium-voltage work?
Commercial electrical design follows the National Electrical Code (NFPA 70), NFPA 99 for healthcare facilities, IEEE 3007 maintenance and operations practices, and energy standards such as ASHRAE 90.1.
NFPA 99 adds essential-electrical-system requirements for hospitals; ASHRAE 90.1 sets the building energy-efficiency baseline that the electrical and mechanical systems are designed to.
Which facilities take service at medium voltage?
Hospitals, university campuses, airports, large retail centers, and other big commercial buildings often take medium-voltage service and own the transformer step-down, rather than taking low-voltage service from the utility.
Owning the step-down means the facility also owns the medium-voltage switchgear, transformers, and distribution past the service point.

Medium-voltage equipment for large commercial facilities.
Large commercial facilities — hospitals, university campuses, airports, and retail centers — increasingly take service at medium voltage and own the step-down to building distribution. The medium-voltage scope includes service-entrance switchgear, transformers, metering, junction cabinets, and secondary connectors, designed to the National Electrical Code and, for healthcare facilities, NFPA 99. IEEE 3007 covers the operation, maintenance, and electrical safety of these systems, and ASHRAE 90.1 sets the building energy requirements.
The commercial scope Hawk MV Supply sources spans the six categories on this page: switchgear, transformers, metering equipment, junction cabinets, secondary connectors, and grounding — from the seven manufacturers listed above.
