<div dir="ltr">Hi Mark,<div><br></div><div>Thanks for that. It makes sense. My preference would be language that said "utility-interactive current" instead of "AC output current". For a bi-directional inverter, I can see how an inspector would assume that the AC output current would be the current supplying the critical load panel and cause confusion.</div><div><br></div><div><br></div></div><div class="gmail_extra"><br><div class="gmail_quote">On Fri, Aug 12, 2016 at 7:39 AM, Mark Westbrock <span dir="ltr"><<a href="mailto:westbrock@positiveenergysolar.com" target="_blank">westbrock@positiveenergysolar.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr"><div class="gmail_default" style="font-family:tahoma,sans-serif">Hi Mac,</div><div class="gmail_default" style="font-family:tahoma,sans-serif"><br></div><div class="gmail_default" style="font-family:tahoma,sans-serif">The wording changed because in the 2011 NEC 705.12(D) you had to use the size of your backfeed breaker in calculating the busbar loading, but in 2014, 705.12(D)(2)(3)(b) now says "125 percent of the inverter output circuit current and the rating of the OCPD protecting the busbar shall not exceed 120%". </div><div class="gmail_default" style="font-family:tahoma,sans-serif"><br></div><div class="gmail_default" style="font-family:tahoma,sans-serif">So, the 2014 wording basically allows all inverters to follow the exception that used to be there for hybrid inverters.
