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.

This is essential for industrial control systems that may contain hundreds or thousands of wires. These numbering schemes are often particular to each facility, but there are tools to help make wire labels that will appear in the final controls cabinet.

Electrical Standard for Industrial Machinery, helps you ensure fire safety by addressing the electrical considerations specific to equipment, apparatus, and systems used in industrial manufacturing processes.

The control panel may be isolated but the lamp will require power so that the engineer can see while working on it.

It needs to be cut with a valve seat cutter. A valve seat cutter is also an expensive tool but not as expensive as a valve grinder.

A circuit is a closed loop of wiring and components beginning at the positive side of the battery and ending back at the negative side of the battery. This loop is often closed using a common ground. Electricity only flows when a circuit is a closed loop. If the loop is open no electricity flows.

This was just a basic overview of wiring concepts. You can add additional components to your tractor such as safety switches, fuses, ammeters, hour meters, indicator lights, etc. They all will be wired in a similar fashion to above. The most important concept to remember is you need a closed loop or circuit to have electrical flow, and it’s best to visualize your wiring in separate circuits.

Two of the phases are also connected to the transformer to power the logic. The start and stop buttons are at the left of the box (note: normally these are mounted elsewhere, and a separate layout drawing would be needed).
