FAQs
Installation begins with locating a suitable enclosure, ensuring the NEMA 3R rating covers the intended environment. The plug-in socket design simplifies wiring, and the unit supports 3-phase in, 1-phase out with 120/240 Vac operation. Use proper lifting procedures for the 320 lb assembly and secure the unit with the correct mounting hardware. Follow the catalog notes for feeder exit options (top, bottom, or back) to match your panel layout and MCB configuration.
The meter stack is designed for mixed configurations, including 2 sockets with 1-phase out and 3-phase in, along with 400 A main and 350 A secondary breakers installed per the catalog notes. It supports 120/240 V single-phase networks and 208Y/120 V three-phase networks, with a 1200 A bus. Ensure selected MCBs align with the upstream electrical design and clearance requirements.
Yes. The unit carries UL Listed certification and a NEMA 3R enclosure rating, which provides outdoor and damp-location resilience. For outdoor installations, ensure rainproof cap hubs are mounted if exiting from the top and follow the catalog notes on outdoor mounting and weather considerations. Regular inspection and adherence to the warranty policy help sustain performance over time.
The product is UL Listed, confirming compliance with recognized safety standards for electrical equipment. Its NEMA 3R enclosure supports outdoor use, offering protection against the elements. While the data sheet highlights UL Listing, always verify project-specific requirements (local codes and client standards) and keep the warranty documentation (one year from install or 18 months from shipment) readily accessible for audits.
The meter stack reduces installation time with a plug-in socket design, lowering field labor costs and commissioning risk. Its rugged build and UL/NEMA ratings minimize downtime, while the warranty provides protection against early failures. Regular visual inspections and clean connections during scheduled maintenance help sustain measurement accuracy and extend service life, contributing to favorable total cost of ownership in commercial facilities.
