Eaton 37MM420R12 – Frequently Asked Questions

1) What applications use this Eaton 225A meter stack module?
Commercial buildings requiring three-phase 208Y/120V metering. Common in strip malls, office buildings, and multi-tenant facilities. Seven jaws support multiple tenant connections through one main assembly.
2) Is this compatible with standard utility meter bases?
Yes, uses standard 225A three-phase meter sockets. Verify utility requirements for ringless security configuration. Check local utility standards for approved meter base manufacturers and socket specifications.
3) What does the 1200A lever bypass feature provide?
Allows meter servicing without power interruption. Lever operates main disconnect for safe meter removal. Critical for commercial facilities requiring continuous power during meter maintenance or replacement.
4) How does the aluminum bus construction perform?
Aluminum bus provides excellent conductivity with lighter weight than copper. Properly rated for 1200A continuous duty. Use appropriate connection hardware and anti-oxidant compound per manufacturer specifications.
5) What does factory A-B phase balance mean?
Factory pre-configured phase rotation and balance for proper three-phase operation. Ensures even load distribution across phases. Reduces field wiring errors and commissioning time.
6) What NEC articles govern meter stack installation?
NEC Article 230 covers service equipment requirements. Article 408 addresses panelboard and switchboard rules. Follow local amendments and utility interconnection standards. Verify working space clearances per NEC 110.26.
7) Are additional components needed for complete installation?
May require grounding electrode conductor connections, weatherhead assembly, and riser conduit. Check specifications for required mounting hardware and sealing accessories. Coordinate with utility for meter and CT requirements.
8) What are the mounting and space requirements?
Verify manufacturer template for exact dimensions and mounting points. Allow 36 inches minimum working space in front per NEC requirements. Check building structural capacity for assembled weight including conductors.
9) How do you maintain the lever bypass mechanism?
Exercise bypass lever quarterly to maintain smooth operation. Check for corrosion or binding. Verify proper mechanical interlocking function. Perform maintenance with qualified personnel following NFPA 70E safety procedures.
10) Are there similar Eaton meter stack configurations?
Eaton offers various jaw configurations and amperage ratings in their commercial meter stack line. Different socket arrangements available for specific tenant layouts. Browse our Eaton electrical products for compatible options.
11) What field conditions affect performance?
Outdoor installations require proper weatherproofing and drainage. Salt air environments may require additional corrosion protection. High ambient temperatures can affect current ratings. Verify environmental ratings match installation conditions.
