GE, Siemens, Eaton...
maybe I’m missing the question...
MBE2040PV200BTS
copy and put that in your search engine, it’s an Eaton.
I am looking for a Meter with a Main breaker only with copper buss to feed an interior panel.
I checked the Siemens 'Speedfax'.
All Siemens meter mains are aluminum buss.
SQ D catalog looked the same,
Eaton catalog did not specify the buss type, but the one you linked to is a copper buss trailer panel.
Ill look into those more.
Oh Ok! I knew I was missing something.
Siemens MM0202B1200 200-Amp Meter Main Combination
this one says copper buss.
I was a little surprised about Square D, since their QO load centers have a copper bus, but some searching on their website confirmed that on what they call Combination Service Entrance Devices, the bussing between the meter base and the main disconnect is aluminum. See:All Siemens meter mains are aluminum buss.
SQ D catalog looked the same,
