Electrical equipment is usually connected to a battery by straps or cables. A strap is made of wires braided or woven together; a cable is made of many strands of wire twisted together. Cables are usually covered with insulation. Generally, straps and cables are covered by natural or synthetic rubber. Sometimes the rubber is wrapped in one or two layers of braided cotton or silk.

To connect a standard battery to a piece of equipment, an insulated cable is connected from the positive battery terminal to the machine circuit. A ground strap is connected from the negative battery terminal to the ground or frame of the machine. A ground strap is usually not insulated.
