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.

When the current is switched on or off, the electro-magnetic field increases and decreases, rapidly causing, in effect, a radio signal. The effect is similar to the crackle that can sometimes be heard on the radio or television when something like a fridge switches on and off. This radiated signal can be picked up by the other wires in the system and cause interference to the normal working voltages in the system

By Claudie Ulysse. Electrical Wiring. Published at Thursday, January 18th 2018, 16:16:34 PM. A conductor is a material which will allow an electric current to flow easily. In the case of a wire connection, it needs to be a very good conductor. Good conductors include most metals. The most common conductor used in wire is copper, although you may come across others such as aluminium. An insulator on the other hand is a material which does not allow an electric current to flow. Rubber and most plastics are insulators.

Figure 5 below shows a schematic diagram for a PLC based motor control system, similar to the previous motor control example.

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.

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. Engine Wiring. Published at Wednesday, January 17th 2018, 18:38:32 PM. The Emulsion Tube/Main Jet sits below the fuel bowl. This results in the emulsion tube and main jet to constantly have fuel pressure against it. The original design relies on the mating surfaces between the carburetor body and the main jet/emulsion tube to be perfect in order to provide a seal between each other. As corrosion and age set into your carburetor, this seal is often compromised. Since fuel is always being pulled down toward the main jet area, fuel will continuously leak out causing an overly rich air/fuel mixture, and loss of fuel.

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.
