Too bad the black wire wasn't blue, it would have made pic #1 look so much more patriotic (especially when the fireworks start).
I especially like the way the installer so conscientiously left the romex EGC wrapped in paper (pic #3), so it wouldn't "short" to the box.
On a slightly more serious note... judging from pic #4, is this really 3-phase equipment? The white wire wanders out of the picture, unlike the black and red, which are spliced to the unit primary, so maybe it's really a neutral? If so, why the 3-pole disconnect?
