Would this be considered an installation for power quality?
Yep.
If you plan on reinstalling this unit, I would suggest a somewhat larger box, as well as a ground wire run from the ground stud on the filter (between the 2 line terminals) to the ground bus in the panel.
Does the owner realize that this thing offers little to nothing in the way of transient voltage suppression? Maybe you should try to sell a "whole house" TVSS unit along with the service upgrade since the owner seems concerned about power quality...
