29. ELECTRICAL DESIGN AND CONSTRUCTION

Topics:

• Electrical wiring issues; cabinet wiring and layout, grounding, shielding and inductive loads

• Enclosures for industrial environments

Objectives:

• To learn the major issues in designing controllers including; electrical schematics, panel layout, grounding, shielding, enclosures.

It is uncommon for engineers to build their own controller designs. 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. In some factories, the electricians also enter the ladder logic and do debugging. This chapter discusses the design issues in implementation that must be considered by the designer.
