The first thing to mention is the quality of the wire. eXtreme Max Grade wire is a 14-gauge, solid copper core cable. It has a thick, 60 ml polyethylene jacket on the outside of it. It is so durable that you can place the wire on top of the ground, without having to bury it at all, if you so desire. Completely waterproof and UV-resistant, eXtreme Max Grade wire can handle anything that Mother Nature sends its way.
