Jason, Any additional OCPD downstream of the 200A load output breaker could allow for a smaller wire size to be used at these terminals. For example, load output conductors run to a 100A main breaker panel board. Obviously depending on circumstances, a #4 copper could fit the bill.
What I’m 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. -Chris On Sat, Apr 16, 2022 at 5:35 PM Darryl Thayer via RE-wrenches < re-wrenches@lists.re-wrenches.org> wrote: > Hello, The overcurrent device is to protect the conductors. you can put > any size wire, but you must protect with the overcurrent device.
