Taking the PW4260L1225CU panel as an example, it lists the ECMBR2 as a breaker hold down and shows (in the diagram a specific location for back-feeding the breaker). This documentation looks to be tailored for the situation of back-feeding a breaker to serve as the main for the panel. I am asking for the situation where one is installing a stand-alone (not cut off when the grid goes down) solar panel system and / or a battery system. The breaker connecting the stand-alone solar system to the panel would need to be secured [by NEC 710.15(E) it needs to be secured according to 408.36(D) which needs an additional fastener that requires other than a pull to release the device]. As an example for a battery, the Powerwall system breaker connection would also need to be secured per 408.36(D) by their own documentation. Is there any documentation that ECMBR2 can be used in locations other than the upper left as shown in the attached wiring diagram? There are suitable holes down the panel but no documentation I could show my AHJ. This would be for the purpose of back-feeding power from solar or batteries into the panel bus. When one designs their solar to *not* go down when the grid fails, one *can't* make use of your product line of solar ready meter combo products as we need to shutdown the connection to the grid to prevent islanding. Is there anything to prove that the holes elsewhere in the panel could also be used with ECMBR2? Best regards, Richard =============== My dream solar-wheel-hub panel would have a high (250, 300, 400) bus rating and allow breaker securing down the panel. The higher bus rating would allow more freedom in selecting where I could secure the breaker by the NEC; instead of the-other-side-from-the-main.
