Type 4 Freestanding Enclosure, How do I Mount it?
Type 4 Freestanding Enclosure, How do I Mount it?
(OP)
All Enclosure manufactures sell Type 4 & 12 Freestanding enclosures. But they have no means of securing the enclosure to the floor. No instructions. No kit.
UL50 says "Floor supported enclosures are not required to be provided with a mounting means."
I called Hoffman. They had no instruction or advise to give on installation. They just stated that they buid to UL.
Thanks for you help!

If you start making holes in a NEMA 4 panel, you'll need to seal them up somehow to maintain a waterproof panel.
If you worried about seismic events, you'll need to enlist a structural engineer.
A lot of these panels are not bolted down at all - but the conduits help keep them from walking away too far.

Our UL508 inspector had issues with us running ANYTHING through the enclosure which itself did not have a NEMA 4 rating. Made us switch to meyers hubs even for NEMA 12 boxes.
