They are almost certainly MOVs. Shunt mode surge suppressors (MOVs) on branch circuits are a very bad idea -- If equipment plugged in at those outlets are connected to anything plugged in at a differ

It doesn't even have to be connected to something plugged into a different outlet. If the equipment is connected to a tower ground (e.g., transceiver/antenna) and the tower ground is not bonded to t
