It’s a nice enclosure, but they’re mighty proud of that bad boy.
As it’s a UL 508 listed assembly, from what I’ve read, the NEC does not apply.
However, there are rules specific to 508 type devices.
Ref:
The cost for that item alone will more than likely be a showstopper for most users.
WRT the Sense device being installed inside of a load center…
There must be something in the NEC that allows them to do that with a device that
uses a radio link vice a wired connection. (the NEC is a large document)
As a retail company, they have too much to lose if it wasn’t legit to install their
device in a load center.
