FAQs
When planning installation, verify that main tenant feeders can exit from top, bottom, or back, and ensure compatibility with Myer type hubs if mounting on rainproof caps for outdoor use. Confirm voltage compatibility for 120/240 V or 208Y/120 V networks, and plan for a 1200 A bus with 200 A rated main to accommodate future expansion. Ensure UL Listed and EUSERC approved status is recognized by the local utility during interconnection.
The meter stack supports both 120/240 V single-phase three-wire and 208Y/120 V three-phase networks, enabling flexible metering for mixed-use facilities. With a 200 A amperage rating and 225 A socket amperage, it provides solid headroom for peak loads while maintaining safe, balanced feed pathways. This versatility reduces the need for multiple metering assemblies on mixed-voltage sites.
Yes. The unit features an indoor/outdoor enclosure with a NEMA 3R rating, enabling reliable operation in varied weather conditions when properly mounted with rainproof-cap considerations for top-exit configurations. UL Listed and EUSERC approved credentials further support outdoor interconnection with utilities, ensuring compliance during field commissioning and ongoing service.
This meter stack carries UL Listed certification and is EUSERC approved, two key marks that reassure electrical safety, reliability, and utility compatibility.
