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.

When electricity was originally used for practical purposes, it was used for communication in the form of the electric telegraph and the telephone. Petroleum and paraffin lamps were still lighting homes until the late 1800s, when Thomas Edison developed the light bulb.

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

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.

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.

The float should be perfectly parallel to the upper carburetor body or sit slightly lower than level. This keeps fuel below where the two halves of the atmospheric vent meet. Also make sure your carburetor halves are not warped when the bolts are tightened down. If there is a visible gap between the two halves of the carburetor at the atmospheric vent; sand down the two halves until the gap is gone.

From an electrical standpoint, industrial machine equipment and tools - from drill presses to multi-motored automatic machines.
