Eaton Specification Sheet - 124 TB MS20
200 A amperage rating with four jaws and #6-250 MCM line/load lugs provides a high-capacity connection in a single meter socket, reducing the number of terminations. This translates to lower installation labor, fewer potential contact points, and improved reliability in feeders and service entrances. Ring cover with ring protector offers secure, tamper-resistant access and straightforward visual indication of meter status. Bypass is provided via a test block, enabling safe verification without energizing the circuit, which shortens commissioning time. Surface mount mounting method and 1 position design allow for a compact footprint of 6 in depth, 14 in width, and 30 in height, enabling fit within standard enclosures and simplifying site wiring. Material and finish use galvanized steel with ANSI 61 gray paint, delivering corrosion resistance and long service life in challenging environments. Certification and standards—UL listed, EUSERC approved, and 3R rating—support regulatory compliance and utility requirements, reducing project risk. Compatibility with Eaton B-Line series enhances modularity, serviceability, and long-term maintenance planning.

FAQs
Begin by confirming enclosure compatibility with a 200 A service and #6-250 MCM lugs. Mount the unit on a clean, level surface, secure the ring cover, connect line and load conductors to the 4 jaws, and route wiring through the provided test block bypass. Verify 1Ø/3W configuration and ensure UL and EUSERC compliance labeling is visible. Finally, perform insulation and continuity checks before energizing. This process minimizes fault risk and supports reliable commissioning in commercial and light industrial applications.
The 124 TB MS20 supports a 200 A amperage rating with four jaws and both line and load lugs sized #6-250 MCM. It is configured for 1Ø/3W wiring with a ring-type cover and a test block bypass. The product footprint measures 6 in depth, 14 in width, and 30 in height, with a total weight of 32 lb. These specs enable a high-capacity, secure, and code-compliant meter installation.
Yes. The unit carries a 3R enclosure rating and is UL listed with EUSERC approval, making it suitable for both outdoor and indoor service locations. The galvanized steel construction with ANSI 61 gray finish provides corrosion resistance in harsh environments, supporting long service life and reduced maintenance in outdoor applications such as external meter pedestals and building risers.
This meter socket is UL listed and EUSERC approved, with a 3R enclosure rating for reliable protection in varying conditions. These certifications verify electrical safety, utility compatibility, and suitability for outdoor use in many jurisdictions, helping ensure compliance with code requirements and minimizing project risk during procurement and installation.
The 124 TB MS20 combines a 200 A rating with durable galvanized steel, a test-block bypass, and a ring cover, enabling faster field testing and fewer maintenance interventions. Its UL and EUSERC certifications validate compliance, while the ring protector feature reduces tampering risk. Together, these aspects shorten commissioning time, extend service life, and lower lifecycle costs in commercial and light industrial power distribution projects.
