Commercial Meter Stack Modules
Features, Benefits and Functions
- Heavy-duty lever bypass socket design
- Single-phase or threephase designs (35 = singlephase, 37 = three-phase)
- Provision for two-pole or three-pole main tenant breakers
- Phase balance kits are included with three-high and four-high modules
- End Walls
The top cap is removable and does not contain knockouts, so contractors can position and punch holes where they need them. There are numerous KOs in the back and bottom for flexibility.
- Ground Bars
The factory-installed equipment ground bars are provided in both the top and bottom gutters.
- Meter Socket
The 5-jaw meter socket and 7-jaw meter socket includes a built-in manual bypass and jaw release. The ground wire is factory connected in both 35MM and 37MM modules.
- Separate Wireway Cover
If work on the breakers or cables is necessary, it can be accomplished without disturbing the meters or meter covers, thanks to a separate cover that allows easy access to the module’s main tenant breaker and wireway section. (Not shown.)
A solid metal barrier separates the meter socket section from the tenant breaker in the wireway section. The unmetered vertical bus is enclosed to guard against power theft.
- Neutral Assembly
Located in the wireway of each module, the assembly permits convenient termination of the neutral conductors.
- Enclosed Horizontal Bus
Non-removable metal barrier encloses 1200A horizontal bus when passing through the tenant breaker section for added security.
- Tenant Breaker Range
All modules accept 15–225A bolt-on breakers in various AIC ratings. The CHH_X breaker carries a UL listed series rating of 100,000A, which allows you to use standard 10 kAIC breakers in downstream loadcenters and panelboards by Eaton.
- Indoor/Outdoor Construction
Raintight caps, meter covers and lockable raintight tenant breaker covers make it convenient for you to use any of our modules on either NEMA 1 or NEMA 3R applications.
- J. Mounting Rail
Rear mounting rail and wall hanger speed and simplify installation. (Mounting rail not shown.)
- Nameplate and Ratings
The nameplate gives you full rating data: 208Y/120, threephase, four-wire; 240/120, three-phase, four-wire delta (high leg on B-phase); and 240/120 single-phase. (Not shown.)
- Mains and Modules
Slip together quickly, smoothly with frontaccessible captive bolts securing the juncture without removing socket interiors or bus access plate. Main bus joint bolts torque to 25 foot pounds.
