Wires and cables (conductors) are insulated and protected by a variety of materials (insulators) each one having its own particular properties. The type of material used will be determined by the designer who will take into account the environment in which a control panel or installation is expected to operate as well as the application of individual wires within the panel.

Wiring diagrams, sometimes called “main” or “construction” diagrams, show the actual connection points for the wires to the components and terminals of the controller.

A highly disturbing device (variable speed drive, frequency converter, etc.) will have less radiation in the panel if it is “encapsulated” in a small, electromagnetically sealed, unpainted metal enclosure.

Modern electrical machine tool equipment may vary from that of a single-motor machine (such as a drill press that performs simple, repetitive operations) to very large, multimotored automatic machines, which contain highly complex electrical control systems. Typically, these machines are especially designed, factory-wired, tested by the builder and then erected in the plant.
By Blandine Honorine. Electrical Wiring. Published at Sunday, January 28th 2018, 23:39:19 PM. It is uncommon for engineers to build their own PLC panel designs (but not impossible of course). For example, once the electrical designs are complete, they must be built by an electrician. Therefore, it is your responsibility to effectively communicate your design intentions to the electricians through drawings.

However, an exception allows you to install a splice in leads attached to electrical equipment, such as motors and solenoids.

You must totally enclose conductors and their connection external to the control panel enclosure in suitable raceways or enclosures. Unless used for flexible connections involving small or infrequent movements, or connections to normally stationary motors, limit switches and other externally mounted devices, fittings used with raceways or multiconductor cables must be liquidtight.
