FAQs
The 117 TB MS20 is designed for 3Ø/4W metering with seven jaws and #14-2/0 lug connections, enabling straightforward integration into standard three-phase distribution systems. Its surface-mount form factor accommodates common electrical room layouts, while the test block bypass supports routine checks without disconnecting service. For retrofit projects, the unit minimizes field rewiring while preserving metering accuracy.
This meter socket is UL listed and EUSERC approved, providing third‑party verification for safety and electrical compliance. It features a 3R enclosure rating suitable for outdoor or protected indoor installations, and the ANSI 61 gray/mill‑galvanized finish adds corrosion resistance. These certifications reduce project risk and simplify procurement for regulated facilities.
Yes. The unit carries a 3R enclosure rating and uses galvanized steel with a weather‑resistant ANSI 61 gray finish, making it appropriate for outdoor or exposed indoor environments. The combination of ring protector features and robust build helps maintain performance under environmental stress while meeting applicable safety standards.
The ring cover with a ring protector and a test block bypass facilitates safe testing and continuous service during maintenance. Installers should follow standard metering practices for ring terminals (#14-2/0) and ensure secure seating of all lugs. This setup minimizes downtime and supports quick fault diagnosis in field operations.
Plan for a footprint of 12 in width by 24 in height and 4.625 in depth, with an approximate weight of 25 lb. This dimensional profile supports surface‑mount installation in typical electrical rooms and retrofit spaces, enabling efficient planning for mounting clearances, service access, and cable routing around the meter socket.
