<div dir="ltr">Hi Garrison,<div><br></div><div>This is a new one for me - normally we always balance everything when dealing with paralleled conductors. NEC 310.10(H) talks about conductors in parallel and I can't see anything the explicitly forbids what you explained. To be safe, I think it is worth contacting the PE to double check that they were aware that there are three sets of parallel conductors on each phase.</div><div><br></div><div>August</div><div>Luminalt <br><br></div></div><br><div class="gmail_quote"><div dir="ltr">On Tue, Aug 21, 2018 at 8:09 AM Garrison <<a href="mailto:garrison.rie@gmail.com">garrison.rie@gmail.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">Hi Wrenches,<br>
<br>
When making a supply side connection on parallel sets of conductors is it required to tap all conductors on each phase?<br>
<br>
I have a set of plans with an 800A interconnection on a 1200A service. Service has three parallel sets of 500MCM. Plans call for tapping just two conductors on each set of three. Plans are stamped by an EE. I had been working under the assumption that if tapping parallel sets all conductors must be tapped.<br>
<br>
Any issues with not tapping all sets?<br>
<br>
Thanks,<br>
