<div dir="ltr">Jason - <div><br></div><div>Yes, it's definitely a violation of 110.26 to have batteries/enclosures below things like panelboards if the batteries stick out more than 6" past the face of the panelboards (etc). Specifically, it would be a violation of 110.26(A), which is distinct from 110.26(E) (the section that addresses "other systems" such as ducts, etc). 110.26(A) is all about providing a safe "working space" for an electrician to maintain the panelboard, disconnect, etc without having to reach over or around other equipment (of any kind), which would put the electrician in a compromised position when maintaining potentially energized equipment. </div><div>Additionally, the 6" allowance granted by 110.26(A)(3) is only valid if the batteries are "associated" with the electrical installation (which they would be, if the panelboards and other equipment whose working space is being infringed upon are related to the batteries).</div><div><br></div><div>When we are pressed for space, we have built out the wall above the batteries so that the face of the panelboards, etc are within 6" of the outside face of the battery enclosure(s). One example is attached here (with three Powerwalls stacked). </div><div><br></div><div>Best,</div><div>Blake</div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Sun, Jan 31, 2021 at 12:28 PM Jason Szumlanski <<a href="mailto:jason@floridasolardesigngroup.com">jason@floridasolardesigngroup.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr"><div class="gmail_default" style="font-family:arial,helvetica,sans-serif"></div><div class="gmail_default" style="font-family:arial,helvetica,sans-serif">I'm seeing a lot of pictures of LiPO battery systems and people are mounting equipment above them like load centers, inverters with disconnects, and other serviceable enclosures. Some of these battery systems are 24 inches deep or more. This seems to violate NEC 110.26 requirements for the other serviceable equipment, but the pictures are proudly displayed as models of success. Even slender Tesla Powerwalls stick out significantly when stacked 2 or 3 deep and would be more than 6 inches deeper than a standard load center. Sure, the battery cabinets make great places to rest tools while working, but does anyone else see this as problematic? </div><div class="gmail_default" style="font-family:arial,helvetica,sans-serif"><br></div><div class="gmail_default" style="font-family:arial,helvetica,sans-serif">Jason Szumlanski</div><div class="gmail_default" style="font-family:arial,helvetica,sans-serif">Florida Solar Design Group </div><img width="0" height="0" alt="" style="display: flex;" src="https://mailtrack.io/trace/mail/bdd06583d462e3938bb1d19f5a2b8d4e4bf8dda6.png?u=1613865"></div>
