Hi Mac;<br>
<br>
I'm not sure I understand how you would extend the wires without
splicing. BTW you only need to extend the hots, not the neutrals or
grounds. <br>
<b>NEC 312.8</b> sets a cross sectional area limit of 75% for the
splices and wires inside an OCPD Enclosure.<br>
I just found these inline splices to use instead of the infamous
wire nut:

These should make for a cleaner install, and take less precious
space, but I haven't tried them yet.<br>

<div dir="ltr">Hello wrenches,
<div><br>
</div>
<div>We run into many scenarios where we are locating a critical
load panel adjacent to an existing service to make it easy to
move the loads. I've always taken it for granted (as have the
electricians that we use) that we can't do a splice in the
main panel and extend the load wiring to the critical load
panel. Is there code violation for doing a splice in the main
panel and extending the leads to the critical panel? You
would be treating the service panel as a pass-trough/splice
box for those critical loads.</div>
<div><br>
</div>
<div>It makes me wonder because of all of the prewired transfer
switch packages with wire whips already attached that seem to
be designed to do just that.</div>
<div><br>
</div>
<div>Code references would be appreciated.</div>
<div><br>
</div>
<div>Thanks<br clear="all">
