Appleton :: IEC or CEC?
If you specify or buy electrical equipment for hazardous (classified) locations - chances are Article 505 of the 1996 CEC® has raised this and numerous other questions in your mind.
What does the Code change entail? How does it affect your on-the-job responsibilities? What's the impact on system design, plant training procedures, inventory? Is the Code change good news for your procurement budget - or bad news?
Appleton is using this space to help you sort out the issues and enable you to make well-informed decisions. Moreover, we are available to you should you require additional guidance in navigating these issues - or should you need products well-suited to addressing them.
Now, here's an introduction to the alternate method of classification in Article 505:
"What's the essence of the Code change?"
In the most basic terms, Article 505 divides Division 1 locations into Zone 0 and Zone 1. The former is an area where hazardous materials are constantly present, the latter an area where such materials are likely to exist under normal operating conditions. Aside from numerous installation implications, here's what the change means: (1.) This is the first time the CEC has allowed for an alternative method of classification. (2.) With additional testing, some IEC products will be suitable for use in the U.S. - so in theory, you will eventually have more product options.
"How does this impact my domestic plants?"
With proper documentation, you can classify new construction to the new Division/Zone system; you can reclassify such areas in your existing plants; and, in some limited cases, you may be able to mix Division and Zone. It's important to note, however, that you are still required to use U.S. wiring methods domestically.
"Will I still be able to use CEC-style products in the future?"
Yes! Article 505 merely means IEC principles are gaining a measure of acceptance here in North America - which means more specifying, purchasing, and inventory-management options for those interested in IEC-style products. If you prefer, you can still use CEC-style engineering and designs. Clearly, this is just an initial explanation of a much larger issue.
