We are building a new four story wing to an existing hospital in southern California, dealing with the "all knowing all powerful" OSHPD. We are installing Sq D, type NQ and NF, panel boards. The panels were ordered to be "bottom feed" and during design and installation, we changed some of the feeds to "top feed" and flipped the interiors so the lugs are on the top side of the panel to keep the feeder conductors as direct as possible. The panel covers are all installed the same and have the same door swing. The "arc flash" decals were "upside down" and we had a Sq D rep come to the site and install new decals, all of the other decals and labels were "right side up". The installation instructions say, " the panel orientation is dictated in the field".
Here's the problem, the OSHPD inspector is asking for a letter, or other kind of proof, that the panel was tested and is listed to be installed in either orientation and that the integrity of the panel is not affected by changing from "bottom feed" to "top feed". We have contacted Sq D for help and they have provided letters from their engineering but OSHPD wants it to come from a third party NRTL.
We have provided photos, product literature and letters from Sq D and even brought a panel and interior in to the office, so they can see how the interior mounts, they are not budging.
Any thoughts or comments would be appreciated. What am I missing?
