These conductors must be yellow throughout the entire circuit, including wiring in the control panel and the external field wiring. • White or natural gray represents a grounded circuit conductor. • White with blue stripe represents a grounded DC current-carrying circuit conductor. International and European standards require you to use light blue for the neutral conductor. • White with yellow stripe represents grounded AC current-carrying control circuit conductors that remain energized when the disconnecting means is in the OFF position. For additional circuits powered from different sources that remain energized when the main disconnecting means is in the OFF position, you must use striping colors other than green, yellow or blue to uniquely identify the grounded conductors.

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.

Electrical equipment uses a wide variety of wire and cable types and it is up to us to be able to correctly identify and use the wires which have been specified. The wrong wire types will cause operational problems and could render the unit unsafe.

Line diagrams, also called “schematic” or “elementary” diagrams, show the circuits which form the basic operation of the controller. They do not indicate the physical relationships of the various components in the controller. They are an ideal means for troubleshooting a circuit.

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

It only requires finger pressure to make the cut. These cutters hold carbide cutters at perfect angles for cutting your valve seats. Depending on your engine you may need to cut your valve seats with a 46 degree or 31 degree cutter. There is a 1 degree interference angle to allow your valves to wear into the seats to form perfect seals. The valve seat cutters require a perfect valve guide in order to accurately cut the seat.

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.

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.

Now that you have replaced the valves, cut the seats, and confirmed it all makes contact with each other, your engine will start easier, produce more power, and give you less trouble as you work them.
