Tesla:
Yes, a 'pull section' is common here also, along with line-top; load-bottom on CBs. However, a CB could be line-bottom, from the mfg.
Noting the barriers on the lower section of the main, I believe that is the 'line' side.
No provisions for CTs? I have come accross some that use 'donut' CTs out in the pad mount xfr, along with the meter at the xfr location. Not common, but I have seen it.
This also may be downstream from the MSB. Pehaps the OP could shed some more details on this.
