Hi Adam,<br><br>
It ok for the main lugs to be hot. There will always be a hot wire in the
box somewhere. The main lugs are a very safe place to land it. Even with
main breakers, the lugs feeding the breakers are always hot. <br><br>
This is a lot safer than having an "always hot" wire going to a
breaker that could conceivably come loose even with a retainer. <br><br>
Best,<br><br>

Drake if I went from the tap right into the lugs, it would leave those
lugs hot and exposed. Is that my only option though? <br><br>

<dd>Can you come out of the line side tap to the lugs, and connect the
solar to the breaker terminals? This way a retainer clip is not required.

<dd>Sorry I should have elaborated more from the beginning. <br><br>
<dd>Â <br><br>
<dd>I am using the panel as a service disconnect for a lineside
connection (can̢۪t use a fused/bladed disco because of space
conconstraints). 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 N 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. Eaton̢۪s retention options
only start rt in the 60A range (the smaller breakers don̢۪t have the
hole in them to to put the bolt through). Square D said they don̢۪t
have an option fo for their 70A panel. There aren̢۪t any good Siemans
distributors near me be but I wasn̢۪t t finding an option via google
for them either.<br><br>
<dd>Â <br><br>
<dd>I talked with another Wrencher on the phone and received this
feedback which I̢۪m just going to cut and paste to include it it in
this thread:<br><br>
<br>
<dd>“The NEC doesn’t require a hold hold down clamp for the circuit
breaker unless it can be backfed from a multi-mode or stand-alone
inverter (690.10(E)).<br><br>
<dd>The language implies that a hold-down is therefore not required
elsewhere. Most modern breakers (def. QO̢۪s) are not ot marked
“line†¬ and “load†so no problem there (also in in same code
section).<br><br>
<dd>Â <br><br>
<dd>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.†<br><br>
<dd>Â <br><br>
<dd><font face="calibri" color="#1A1A1A">So taken that advice I’m
back to using the QO 70A panel but without a retention clip (or callingÂ
the lid the "retention clip").<br>
</font><br>
<dd>Â <br><br>
<dd><font face="calibri" color="#1A1A1A">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....<br>

<dd>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>

<dd>I’m trying to find a 60A 2 Pole Breakeaker Box that hashas a

be compatible with their 4-8 circuit load centers<font face="calibri">.
What are my options? Thanks!</font>
