I'm trying to connect a heating cable (heating tape) which is constant wattage type. This cable requires 240V. However, I realized there is no ground cable as you can see in the picture below. it only has two identical bus wires that will be heated up. I am going to connect a neutral wire to one of the bus wires and live cable to another bus wire (using temperature controller and SSR).
Is there any way I can ground (earth) this cable? Also, one question is, what is the purpose of the wire that is covering the yellow cable? Is it only for the protection?
