Eaton MB816B200BTS – Frequently Asked Questions

1) Will an Eaton MB816B200BTS meter breaker work for a 200A residential service upgrade at 120/240V?
That's what it's built for. The Eaton meter breaker main is rated 200A single-phase at 120/240V, which is the standard residential service entrance configuration in North America. It combines the meter socket and the service disconnect in one enclosure, so a service upgrade needs one unit on the wall instead of a separate socket and panel.
2) Can this Eaton all-in-one meter breaker be mounted outside on an exterior wall?
Outdoor mounting is the intended use. The enclosure is NEMA 3R, which is the rain and sleet rated construction used for service equipment on an exterior wall. The enclosure and bus are aluminum, so there is no painted-steel rust path at the meter ring.
3) How many branch circuits do Eaton MB series meter breakers hold, and which model has the most spaces?
Two circuit counts are offered. The MB816B200BTS and MBX816B200BTS carry 16 circuits; the MBT48B200BTS is the 8-circuit unit. If the house needs anything close to a full complement of branch circuits, take the 16-circuit version, or plan on feeding a separate subpanel from the 8-circuit unit.
4) What size service entrance conductors and ground can I land in the Eaton 200A meter breaker?
The ground terminal takes #6 through 350 kcmil, which covers the usual copper and aluminum grounding electrode conductors on a 200A dwelling service as well as oversized runs. Feed is top or bottom, so the same unit works with an overhead drop or an underground lateral.
5) Is the Eaton meter socket four-jaw or five-jaw, and which do I need?
Four-jaw. That is the single-phase 120/240V three-wire socket, the one used for a standard residential service. Five-jaw sockets are for network or certain three-wire configurations the utility specifies separately, so if your power company's spec sheet calls for five jaws, this is not the unit.
6) Does this Eaton meter breaker have a bypass so the meter can be pulled without killing power?
It has a lever bypass. The lever shunts the socket so the utility or the electrician can pull the meter for change-out or testing while the load side stays energized. That is the feature many utilities require on a 200A residential socket, and it is what separates this from a plain non-bypass socket.
7) Is the Eaton meter breaker UL Listed and approved by my utility?
It's UL Listed, and it carries a utility approval for Ameren in Illinois. Utility acceptance is issued company by company, so on a service outside Ameren territory the local power company's approved equipment list governs which socket they will set a meter in.
8) Do I need a separate meter socket and load center, or does this Eaton unit replace both?
One unit does both. An all-in-one combines the meter socket, the 200A main disconnect, and the branch breaker spaces in a single NEMA 3R enclosure, so a service entrance needs one set of terminations instead of a socket outside feeding a panel inside. The trade-off is that the branch breakers live outdoors at the meter; if you want the distribution panel in a garage or utility room, use a separate meter socket and run service entrance conductors to an indoor load center instead.
9) Is the bus in the Eaton MB series meter breaker copper or aluminum?
Aluminum bus. That matters at termination time: land conductors on the lugs with the correct torque and use an antioxidant compound where the utility or the inspector calls for it on aluminum connections. The enclosure is aluminum as well, which is why it holds up in an outdoor NEMA 3R location.
