For example, load output conductors run to a 100A main breaker panel board. Obviously depending on circumstances, a #4 copper could fit the bill. </div><div dir="auto"><br></div><div dir="auto">What I\u2019m not extremely excited about with the new design is that in an off-grid scenario with a generator and smart load, we would now need to integrate an AC disconnect for generator input (grid) and either a fused disconnect or loads panel for any smart load output. With the 12K unit, the integrated breakers help cut down on BOS and install time. </div><div dir="auto"><br></div><div dir="auto">-Chris </div><div dir="auto"><br></div><div>On Sat, Apr 16, 2022 at 5:35 PM Darryl Thayer via RE-wrenches <<a href="mailto:re-wrenches@lists.re-wrenches.org">re-wrenches@lists.re-wrenches.org</a>> wrote:<br><div class="gmail_quote"><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left-width:1px;border-left-style:solid;padding-left:1ex;border-left-color:rgb(204,204,204)"><div dir="ltr"><div class="gmail_default" style="font-family:"times new roman",serif;font-size:large">Hello, The overcurrent device is to protect the conductors. you can put any size wire, but you must protect with the overcurrent device.
