<div class="moz-cite-prefix">Fortunately we haven't had that AHJ
'problem'. It probably wouldn't work (in the mind of your AHJ) to
move the heavy loads to one side and install your backfed breaker
on the far end of the 'lighter' side of the center tap. I know
I'm probably dreaming..... It seems the 2 buses must be designed
to handle 100 amps on both sides of the center tap to deal with a
worst case scenario....how many times have we all seen a X rated
panel (center tap or not) have 2X worth of CBs for the loads. Can
you contact the manu of the panel to confirm the rating of the bus
on either side of the center tap?<br>

<p class="MsoNormal">We are seeing more AHJs not allowing us to
use the NEC 7015.12(D)(2)(3)(b) 120% rule on center-fed
panelboards. For example, if we have a 100 A meter/main combo
with a center fed 100 A breaker we cannot apply the 120% rule
at all and need to do a panel swap. What are other wrenches
doing in this case?</p>
