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.

You're permitted to use wiring channels if they're made of a flame-retardant insulating material. If you're working with back-connected control panels, you must provide access doors or swing out panels that swing about a vertical axis. Multiple-device control panels must have terminal blocks or attachment plugs and receptacles to terminate and connect all outgoing control conductors.

If the screen is to be connected then make it off in the same way as for coaxial cable with a soldered pigtail and a sleeve.

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

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.
By Blandine Honorine. Electrical Wiring. Published at Sunday, January 28th 2018, 23:39:19 PM. Workshops manufacturing parts in PVC or rubber use high-frequency welding processes to perform assembly. The propagation of strong magnetic fields and high-frequency waves is not easily controllable.
By Severin Theodore. Electrical Wiring. Published at Sunday, January 28th 2018, 21:58:26 PM. The combined cross-sectional area of all conductors and cables is not permitted to exceed 50% of the interior cross-sectional area of the raceway. The fill provisions are based on the actual dimensions of the conductors or cables used.
By Annette Noele. Electrical Wiring. Published at Sunday, January 28th 2018, 19:28:59 PM. The dedication of panels by power class is the most efficient measure to obtain an excellent “EMC” result. Moreover, separate routing of disturbing and sensitive cables ensures minimum coupling.
