Color-coded conductors let you identify and attach each circuit quickly, while the thicker copper layer gives better electrical performance than typical aluminum-only wires. The cord is offered in multiple lengths so you can choose the span that fits your towing configuration.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this wire improve trailer electrical reliability?\u003c\/h3\u003e\n\u003cp\u003eThe construction blends aluminum strength with a heavier copper coating to reduce resistance compared with standard CCA or pure aluminum wires.
