Capacity and configuration: The 200 A rating aligns with mid-size commercial and light industrial feeders, enabling a single, consolidated metering point for many projects. This unit supports both overhead and underground feed configurations, so you can standardize metering across diverse sites without sacrificing performance. In practice, engineers design layouts around the 324 C NB - MTR 320A 4J, which simplifies conduit routing, reduces the number of components, and provides headroom for future loads as facilities expand. Mechanical integrity: The ring-type contact with four jaws delivers a low-resistance, high-reliability connection that resists loosening under vibration and temperature cycling. The 2-position option matches common panel geometries and makes phase alignment easier during commissioning, decreasing field errors and accelerating startup in busy electrical rooms. Durable construction and installation ease: Built from steel with a painted finish, the socket withstands harsh shop and field conditions, resisting corrosion and impact. Its surface-mount design supports fast retrofits and new-build installations in standard enclosures, reducing the need for custom housing. The unit’s 65 lb weight adds stability on mounting surfaces, helping to prevent movement during service or in seismic zones. Compliance and utility readiness: UL certification and EUSERC approval ensure adherence to safety and interconnection standards utilities require, minimizing approval delays. The product’s 1Ø/3W specification further aligns with common single-phase metering practices, enabling straightforward integration with typical panelboards and feeders without complex adapters. Lifecycle and ecosystem: Being part of the Eaton B-Line family means easy access to compatible accessories and spare parts, shortening maintenance cycles and keeping metering points consistent across sites. This socket’s robust construction and clear documentation reduce support costs and improve total cost of ownership for building operators and integrators.
