Hey Bill,
Yes that's pretty much it. Stand-Alone Meter Socket to J-Box with
Splice Tap to Solar Disco and Main Breaker Panel. Max backfeed 200 Amps
(160 Amps rated solar inverters) for single phase.
You'll need to meet the Short Circuit Current Rating (SCCR) for all
equipment and the IC (Interrupting rating) for all overcurrent
protection that is required by the particular transformer - service
entrance circuit. 22kAIC minimum is usually what is needed to meet a
200 Amp service supply side connection.
If you have a residential account with PG&E then Greenbook section 6 is
the equipment you need to meet.
If you have a commercial account with PG&E then Greenbook section 7.
I just proposed to PG&E to use a Eaton (Cooper) B-Line CIR 124TB as
you'll need test bypass blocks as per the Greenbook for commercial.
I plan to follow Bill Hennesey's advice and use Ilsco Splice Taps for
the "T" - I plan on using a steel J-box as I'm outdoor in the sun.
Then I feed to an Eaton 200 Amp Heavy Duty Safety Switch for the solar
with a combined fuse/switch AIC of 200kA
Then I feed also to a Main Panel with a breaker/panel rated to 22 AIK -
some homeline panels meet this criteria and many standard main breaker
Square D and Siemens panels can be found for this.
That's it from my end - just submitted this to PG&E this morning and
will drop by and check with my AJH this week to make sure it all works
for everyone.
Hope that helps.
Best,
Jeff
I just sent my PG&E proposal

After ruminating on Jeff's inquiry about various ways to do a supply
side connection, I came up with the attached drawing. Verbal
descriptions are harder for me to wrap my head around. This is in PG&E
territory, its 3 phase and I too am trying to avoid the extra cost of
higher Amp panels. Please pick it apart.
Thanks,
Bill
