Applying IEC standards to Industrial Power Distribution Systems and Equipment

North American and Pacific Rim engineers with ANSI/NEMA background who need to work with the International Electrotechnical Commission (IEC) Standards will encounter many sources of misunderstandings and pitfalls:

• misinterpretation of the applicable standards due to partial understanding,
• confusion by applying concepts of another standards system to IEC equipment,
• using values which have a different meaning in another standards system,
• incomplete specifications leading to incorrect options taken by manufacturers,
• using obsolete standards.

This Application Guide discusses these points in a “tutorial handout”-style from the general perspective looking down at the detailed equipment concerned.

You can select the whole guide or only the parts you are interested in.
