Eaton MBB200BTS – Frequently Asked Questions
1) Is a four-jaw meter socket the right one for my service, or do I need a five-jaw?
Four jaws is the single-phase 120/240V three-wire configuration, and that is what the MBB200BTS provides. The fifth jaw is used where the utility requires a network or three-phase meter, so if your utility spec sheet calls for five jaws this unit will not accept their meter. Confirm the jaw count on the utility's service requirement before you set the can, because swapping it after the mast is up is a whole redo.
2) Is the Eaton MBB200BTS approved by my utility?
The approval carried on the MBB200BTS is Central Maine Power in Maine. Meter equipment has to appear on the serving utility's accepted list before they will set a meter, and that list is utility by utility. If you are outside CMP territory, check the unit against your own utility's approved meter socket list before ordering.
3) Does the Eaton MBB200BTS have branch circuit spaces, or do I still need a load center?
This is a meter main, not a combination panel. It gives you metering plus a 200A main breaker for service disconnect and overcurrent protection, and nothing else. You still run feeders from it to a separate load center for your branch circuits. If you want the meter, the main, and the breaker spaces all in one outdoor can, you want a combination meter load center instead.
4) Can I use this Eaton meter main on a 208V three-phase commercial service?
No. The MBB200BTS is single-phase only, rated 120/240V, with a four-jaw socket. A three-phase service needs three-phase metering equipment and a different jaw configuration. Use it on single-phase residential, small commercial, professional office, or retail services drawing up to 200A.
5) Can I feed the Eaton MBB200BTS from underground, or does it have to be an overhead drop?
Both work. Feed type is top/bottom, so the MBB200BTS accepts an overhead service entrance through the top or an underground lateral coming up through the bottom. That is the difference between a meter main you can use on a riser and one that locks you into a single approach.
6) What size grounding and neutral conductors will the Eaton 200A meter main lugs take?
The ground terminal range is #6 through 350 kcmil. That covers the grounding electrode conductor on a 200A service and gives room for oversized aluminum service conductors on longer runs, so you are not fighting a lug that is too small at rough-in.
7) How big is the Eaton MBB200BTS and how heavy is it to hang?
Measures 25 x 14.44 x 5.38 inches and weighs 33 pounds. That is a one-person set on a stud wall if you preload the top screws, and the 5.38 inch depth matters when you are planning clearance on a narrow side yard or an alley wall.
8) What is the model number to order and what breaker is inside it?
Order Eaton MBB200BTS. The main breaker inside is the CSR2200, a 200A device, so if you are matching an existing installation or specifying a replacement main, that is the breaker catalog number to reference.
9) Does the Eaton meter main have aluminum or copper bus, and does it matter for the inspection?
Bus is aluminum on the MBB200BTS. It is UL Listed as assembled, so the bus material is not a compliance issue. Practically it means you torque the lugs to spec and use the correct antioxidant practice on aluminum service conductors, same as any aluminum bus service equipment.
