The Standards and Regulations addressed here on this site overwhelmingly apply to the prevention of explosion and fire. Proper sizing of short circuit protection components and the size of conductors being paramount. Standards and Rules, by their very nature have a complex structure: multi-paragraphed, sectioned, sub-sectioned, exceptions, cross references within and without. Consequences of not getting the protection and sizing right range from none, (yes none! because the very fault conditions protected against, by good fortune, happen never to occur), to complete disaster when they do occur and even coincide with other bad luck and so lead to damage to machines, and injury to people.
In between the extremes lie the less reported incidents requiring remedial measures and the large amounts of monies and other repercussions associated with them (field modifications, lawsuits, compensations, loss of production and jobs, individual liability, harm to careers and reputations).
Recommended Users:
Corporate Level: There are legal liability and business reputation issues. It will be an advantage over those that do not if your company can keep up with the rules.
Engineering Managers: You can have your engineers record and document their work. Good for them, good for you, good for the company, good for the equipment, good for your customers and their end users. Better than before. (Add performance goal into annual assessment tasks).
Design Engineers: Keep those Standards and other references and materials close by but in your bookshelf for now. Use these (power) tools first, produce the results, then verify. Have your junior engineer check existing designs: great training and potential for improvements.
CAD Designers: You may use these tools under the direction of your engineer. Present the drawings and the print-outs or electronic versions from the tools fully documented under the project for approval. (Good to add an engineering function into your job description at review time).
Student Engineers: You can try these tools as a learning aid. (With the back-up notes, user guides, and integrated explanations back to paragraph levels of the Standards, you can dig deep mostly without leaving the site). It may help to add some examples to your portfolio for job interviews.
Inspectors: You can apply these tools to the equipment that you are looking at or ask for copies produced by their designers. Of particular interest would be breakdown design for branch circuit and feeder circuits protector ratings, and conductor sizes in those circuits.
AHJ: You may like to require records from these tools to be part of the documentation for the installation.
