Note that I do NOT recommend MOV surge suppression products, which
is what these devices are. MOVs can be really bad news on branch
circuits, because they can actually CAUSE destructive failures of
interconnected equipment. The only good application for them is as
part of a "whole house" suppression system installed at the service
entrance. For a technical discussion of this, see the Power and
Groudning tutorial or the RFI tutorial on my website.
