<p class="MsoNormal"><span style="font-family:calibri">Sorry I should have elaborated more from the
beginning. <span></span></span></p>
<p class="MsoNormal"><span style="font-family:calibri"> </span></p>
<p class="MsoNormal"><span style="font-family:calibri">I am using the panel as a service disconnect for
a lineside connection (can’t use a fused/bladed disco because of space
constraints). Originally I bought a QO 70A panel, but soon realized that the
Square D retention clip (PK2MB) is only compatible with their larger panels. So
I bought a larger panel (100A 8 Circuit) and then received some feedback that
having the open spaces (even if labeled that “Do Not Add Loads”) could raise a
flag with an inspector. So then I was back on the hunt for a dedicated 2 Pole
60A or 70A panel with a compatible retention clip for a 30A breaker. Eaton’s retention
options only start in the 60A range (the smaller breakers don’t have the hole
in them to put the bolt through). Square D said they don’t have an option for
their 70A panel. There aren’t any good Siemans distributors near me but I wasn’t
finding an option via google for them either.<span></span></span></p>

<p class="MsoNormal"><span style="font-family:calibri">I talked with another Wrencher on the phone
and received this feedback which I’m just going to cut and paste to include it
in this thread:<span></span></span></p>
<p class="MsoNormal"><span style="font-family:calibri"><br>
“</span><span style="font-family:calibri;color:rgb(26,26,26)">The
NEC doesn’t require a hold down clamp for the circuit breaker unless it can be
backfed from a multi-mode or stand-alone inverter (690.10(E)).</span><span style="font-family:calibri;color:rgb(26,26,26)"><span></span></span></p>
<p class="MsoNormal"><span style="font-family:calibri;color:rgb(26,26,26)">The language implies that a hold-down is therefore not required
elsewhere. Most modern breakers (def. QO’s) are not marked “line” and “load” so
no problem there (also in same code section).</span><span style="font-family:calibri;color:rgb(26,26,26)"><span></span></span></p>
<p class="MsoNormal"><span style="font-family:calibri;color:rgb(26,26,26)"> </span><span style="font-family:calibri;color:rgb(26,26,26)"><span></span></span></p>
<p class="MsoNormal"><span style="font-family:calibri;color:rgb(26,26,26)">Even
when it was a requirement for all PV outputs, John Wiles had argued that taking
off the panel cover, which required a tool, served as the hold-down, and this
was generally accepted.”<span></span></span></p>
<p class="MsoNormal"><span style="font-family:calibri;color:rgb(26,26,26)"> </span></p>
<p class="MsoNormal"><font color="#1a1a1a" face="calibri">So
taken that advice I’m back to using the QO 70A panel but without a retention
clip (or calling the lid the "retention clip").<span></span></font></p>

<p class="MsoNormal"><font color="#1a1a1a" face="calibri">For
what its worth I have passed inspections prior using the retaining clip from a generator interlock kit
(QOCGK2C) on a QO 100A panel, but felt like there must be a better option out there....</font></p>

Siemens has main breaker retainers. The retainers for QO seem work on
some boxes and not others. It doesn't work on 6 space boxes I've
purchased, but does work on the 8. <br><br>

I’m trying to find a 60A 2 Pole Breaker Box that has a compatible
retaining clip. The QO retaining clip (PK2MBCP) seems to only be
compatible with their 4-8 circuit load centers<font face="calibri">. What
are my options? Thanks!<br>
