Ensure that identification tags and cable markers are legible, marked with a permanent ink and suitable for the environment where the panel is to be used. They should also correspond with those shown in the machine drawings and instruction or service documentation.

There are quite a few symbols used to represent the devices used in home electrical wiring but some of them are very similar, so care should be used when working with them!

The control panel may be isolated but the lamp will require power so that the engineer can see while working on it.

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, February 11th 2018, 07:33:20 AM. Connections should be secured against accidental loosening. Correctly tighten terminal screws and where a connecting plug is fitted, use the clamps or screws provided to secure it to its mating socket.

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.

The terminations of shielded or screened conductors should be terminated so that the screen cannot fray. 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.
