CH Meter/Breaker Combo Question - No Main Breaker

[SingleSided]

Hello,
Questions in reference to a CH/Eaton MB1212L200BTS. It's a combination box with the meter on top, 12 circuits below and only a main lugs. So although it is a main (meter combo) panel has no disconnect. From what I've read, it's primary purpose is as a service box with 6 double pole breakers. 6 throws and all power is off, which is Code compliant and hence no requirement of a main disconnect.

My question is about serviceability. Does this panel work like a split panel? If the 6 switches are thrown (off) is the panel de-energized? Else how would one add any future circuits without pulling the meter (and who'd want to do that...)

Thanks!

The "MB" in the stock number usually means its a main breaker panel.

Welcome to the forum!

ETA: looking this up, apparently they broke their own rules about "MB" meaning main breaker. In this case it is "meter breaker".
Turning off any/all of the six breakers does not de-energize the panel any more than turning off a main breaker in a main breaker panel does. Turning off the main does kill the panel below the main but there is still voltage present.

Thanks for the response. The panel does not have a main breaker. The "L" in the part number is for Main Lug type. Added a couple pics and the label in the breaker is that of Fig 26 page 11. The MB is for Meter Breaker (i.e. combo box).

Thanks Again.

I edited my post to reflect that, probably while you were posting.

Our responses crossed. Thanks, that's what I thought on the MB definition.

That's discouraging...pulling the meter to add a circuit?

Don't know of anyone that does that.

You would only need to pull the meter to de-energize the lugs, and that should theoretically supply a main breaker either near this panel or within the supplied panel.

The 90amp breaker in the panel supplies a sub panel in the garage with the remaining home circuits.

Pulling the meter kills the lugs but also the bus in this case, unlike service with a main breaker which will have only energized lugs when the breaker is off. Thanks for the responses. With all circuits off effectively no different than a mains box at that point, given the bus is covered by breakers.

Appreciate the time...
