For example, once the electrical designs are complete, they must be built by an electrician. Therefore, it is your responsibility to effectively communicate your design intentions to the electricians through drawings.

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.

A highly disturbing device (variable speed drive, frequency converter, etc.) will have less radiation in the panel if it is “encapsulated” in a small, electromagnetically sealed, unpainted metal enclosure.

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.

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.
