FAQs
This meter stack supports main tenant feeders exiting from the top, bottom, or back of the enclosure, offering installation flexibility to accommodate diverse panel configurations. The plug-in socket design simplifies wiring and reduces commissioning time, making it ideal for retrofit projects where space and routing constraints are common. Its 66.625 inch length and 19.375 inch width establish a predictable footprint for planning and procurement.
The unit is a 400A amperage rating with 120/240V operation, supporting three-phase in and single-phase out. It features a five-jaw main and two sockets for metering, and it is designed for ringless installation. These specs enable centralized metering for mixed-load facilities while maintaining compatibility with common commercial service equipment.
Yes. The meter stack employs a NEMA 3R enclosure and is UL Listed, providing outdoor reliability and safety compliance. This combination is well-suited for exterior installations, rooftops, or weather-exposed mechanical rooms where metering must endure environmental exposure without compromising accuracy or safety.
The primary certification is UL Listing, signaling compliance with safety standards for electrical equipment. The NEMA 3R enclosure rating further confirms suitability for outdoor or weather-protected installations. Together, these features support regulatory adherence and reduce risk during inspections and audits in commercial facilities.
Maintenance concerns center on ensuring clean connections and periodic inspection of the plug-in sockets and enclosure seals. The plug-in design minimizes on-site wiring changes, reducing downtime during upgrades. The robust UL Listed certification and outdoor-rated enclosure contribute to longer service life, lower replacement costs, and improved energy management data quality across facilities.
