<p class="MsoNormal">Seems like the logical place for it… and so far Tom and Bill on this list have the best suggestions… if this isn’t hardware hacking I don’t know what is…<o:p></o:p></p>

<p class="MsoNormal">Here’s my problem… it might have an electronic fix but it more likely is an EE101 and NEC code thing…<o:p></o:p></p>

<p class="MsoNormal">In the aggregate I am fine on current (36A < 40A) but my grains are a little course here… is there a way to load balance the 20A services? There are some rather esoteric tie-bar and breaker ganging ideas out there but I would have to convince
an electrician I would deploy this box only under certain conditions (like the upstream wiring being specced for 40A)…<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">We spent a lot of time upgrading the servers; I suppose I could downgrade them to the point that I could put 2 on one circuit… this is an odd problem and stems from the SCC we are entering next month… kind of a dumb rule seeing as we are
supposed to be solving real-world problems…<o:p></o:p></p>
