Eaton 3MMBK – Frequently Asked Questions

1) Which Eaton metering stacks does the 3MMBK barrier kit fit?
The 3MMBK barrier kit is built for Eaton 1MM and 3MM modular metering stacks, specifically ringless stacks with lever bypass. If you are working on a 35MM or 37MM modular stack instead, the part you want is 37MMBK, which is the same kit family sized for that series. Match the stack series stamped on the enclosure before you order, because the two barriers are not interchangeable.
2) Can I use the 3MMBK barrier on a ring-type meter socket?
No. This barrier is made for ringless stacks with lever bypass in the Eaton 1MM and 3MM modular lines. Ringless enclosures use a different cover and internal arrangement than ring-type sockets, so the barrier will not locate correctly in ring-type gear. Confirm your stack is ringless with lever bypass before ordering.
3) What does a barrier kit actually do inside a ringless metering stack?
It provides internal separation between compartments inside the modular metering stack enclosure, so meter positions and bypass hardware are physically isolated from one another. On lever bypass stacks that separation is what lets a meter be pulled or serviced without exposing the rest of the energized stack. It is a sheet barrier that drops into the enclosure, not an electrical device in its own right.
4) How big is the Eaton 3MMBK barrier and will it clear the gear in my stack?
The barrier measures 8.8125 inches wide by 5.5 inches high by 0.375 inches deep and weighs 0.3 lb. That 3/8 inch depth is the number that matters for clearance, it is a thin panel meant to sit between compartments rather than take up wiring space. The footprint is set by the 1MM/3MM enclosure it was made for, so if your stack is that series it lands where it is supposed to.
5) I manage an apartment building, is this the right part when a utility asks for barriers in the meter stack?
For Eaton modular ringless metering stacks in multi-family service, this is the factory barrier kit that provides the compartment separation. It is used in apartment, condominium, and multi-unit residential metering, including service upgrades. The one thing to verify is the stack series: 1MM/3MM takes 3MMBK, 35MM/37MM takes 37MMBK.
