Wire, hookup wire to be specific, is the unsung hero of a control system. Making the connections is what ties all the electrical hardware together. Since one bad wire can spoil the show, there are several essential considerations when selecting what type of wire to use in a control system. Unless some special requirement is needed, stranded copper wire is almost always used to supply power and control signals to most everything we connect. The wire size selected is not always based on ampacity—the maximum conductor current capability before damage—but is often dictated by an end-user specification. Although the specification may call for all signal wires to be 14…Full Story
