electrical equipment that might create a spark (such as with a relay or switch or circuit breaker) can be below 18", that may be the case. I might be completely off base here, but I don't think it has anything to do with it being a battery really, but just
a piece of electrical equipment that might have relays or sparking things inside? Maybe? In which case... does the 5p have any relays or contactors, or is it's BMS all solid state? And second question would be can you document that.<o:p></o:p></p>

We all know there is no open flame from an ESS and I know the 9540A depicts a battery at 6-inches.<br>

Anybody run into this and have suggestions on what I might show back to the AHJ?<br>
