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.

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.

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.

Insert the valve cutter pilot into the valve guide, and gently place the appropriate valve cutter into the pilot. Using the “T” handle apply gentle finger pressure downwards while rotating the tool. This is all it takes to cut into the valve seats. Do this for a few revolutions. Finish, by turning the “T” handle a few times without applying finger pressure. When done correctly you should see that you have cut a uniform area around your valve seat. Repeat this process with your other valve 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.

Now that we have a basic idea of electrical theory, let’s examine how it is all wired together. The example below illustrates wiring for an engine that uses battery ignition and a stator charging system.

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.
