Once you do, you are able to read diagrams quickly, and can often understand a circuit at a glance. The more you work with both line and wiring diagrams, the better you will become in analyzing them.

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.
By Claudie Ulysse. Electrical Wiring. Published at Tuesday, January 23rd 2018, 21:01:41 PM. Wiring diagrams show the connections to the controller. Wiring diagrams, sometimes called “main” or “construction” diagrams, show the actual connection points for the wires to the components and terminals of the controller.
By Augustine Yvonne. Electrical Wiring. Published at Tuesday, January 23rd 2018, 20:07:12 PM. 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.

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.

However, an exception allows you to install a splice in leads attached to electrical equipment, such as motors and solenoids.
By Claudie Ulysse. Electrical Wiring. Published at Tuesday, January 23rd 2018, 16:06:25 PM. Conductors and cables should run from terminal to terminal without any intervening joins. This refers to making a joint in the middle of a wire or cable. If it is necessary for any reason then use a suitable connector or terminal block. Don’t use a twisted and soldered joint.
By Claudie Ulysse. Electrical Wiring. Published at Tuesday, January 23rd 2018, 14:12:24 PM. 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.
