I sent my electrician the wiring diagram from the Caldera pre delivery guide for a Utopia Tahitian and he said to order a #6 4 wire all copper for the hook up. Right now I only have the #6 4 wire to run electrical. Looking at the diagram it looks to me there needs to a completely different type of wire for the whip? Can someone clarify for me if I can use a cut of the same wire or do I need to pick up additional wires. Thanks!
