Abstract: A protector is made of electrical insulating material. It has a central member sized and shaped to fit over the top of an insulator attaching a power wire to a support structure. The central member has a first connecting structure and a second connecting structure unitarily formed therewith and extending away. A first arm is connected to the first connecting structure to extend away therefrom; and a second arm is connected to the second connecting structure to extend away therefrom. The arms have apertures selectable for attachment to wires of different dimensions. The arms also have internal and external facing ribs to register with the internal and external facing ribs of the first and second connecting structures to effect a snug mechanical connection.
