<div dir="ltr">We have found it so much simpler to not have to deal with 400a rated equipment, and to just to a supply side connection. We have used taps such as the ILSCO PBTD series, inside a typical plastic junction box that comes between the 200A meter and any service disconnect. It is also not much more expensive to make sure all panels and main breakers are rated at 22kair. If the inverters are nearby, you could just install a 200A main breaker panel for the solar combiner, and the main breaker in there counts as the service disconnect, so no additional 200A fused disconnect is needed. <div><br></div><div>Apologies if something in 2017 code makes this all not possible, as we are still on 2014 in NY.

<br>
Yes so you were on to it - but with the addition of having that
downstream of a separate 200 AMP meter box and 200 A Main that works :)
Otherwise PG&E would call it a 400 Amp service which for commercial
accounts means having to have CTs for the metering.<br>
<br>
Thanks!,<br>

in your jurisdiction, you might be best served by installing a new 200A
fused service disconnect ahead of the existing main service panel. Or
even a 400A one to allow for additional work inside (CT\u2019s), then perform
a supply side connection in it. Some manufacturers of switchgear have
an option for lugs that accept multiple conductors, so no piercing of
conductors needs to happen.<u></u><u></u></span></p><p class="MsoNormal"><span style="color:windowtext"><u></u> <u></u></span></p><p class="MsoNormal"><span style="color:windowtext">Good luck,<u></u><u></u></span></p><p class="MsoNormal"><span style="color:windowtext">Glenn<u></u><u></u></span></p><p class="MsoNormal"><span style="color:windowtext"><u></u> <u></u></span></p><div><div style="border-right:none;border-bottom:none;border-left:none;border-top:1pt solid rgb(225,225,225);padding:3pt 0in 0in"><p class="MsoNormal"><b><span style="color:windowtext">From:</span></b><span style="color:windowtext"> RE-wrenches

[RE-wrenches] SolarReady Service Panel vs adding Supply Side
connection?<u></u><u></u></span></p></div></div><p class="MsoNormal"><u></u> <u></u></p><p class="MsoNormal" style="margin-bottom:12pt">Esteemed Wrenches,<br><br>I
am in need of changing out an existing 200 Amp service entrance in
order to accommodate a bus capable of handling a a 200 Amp Solar
backfeed (41 KW system) . <br><br>PG&E is upgrading the transformer
to handle the backfeed but when I proposed a Siemens SolarReady 400 Amp
service entrance they couldn't approve it cause since the building is a
shop - they classify it as commercial and require a panel that can
handle CTs when there is a 400 Amp service involved.<br><br>Anyone else
faced with this have solutions? What is the cheapest equipment I can
provide to satisfy all requirements?<br><br>We don't need to upgrade the
existing 200 amp service entrance equipment for load purposes - only to
meet the bus requirements of backfeed.<br><br>Would it be cheaper and
easier to use the existing (or new) 200 Amp residential panel - not call
it a 400 Amp upgrade but simply add a 200 Amp Supply Side Connection?
Suggested equipment to do that in the most economical manner?<br><br>Any
