Zones and Divisions - Why the increased interest in North America?

The US National Electrical Code (1999) and the Canadian Electrical Code (1998) recognize the use of the Zone system of Hazardous Location classification, as used in Europe and other parts of the world. This provides the opportunity for electrical products designed for European hazardous locations to gain acceptance in North America. Also, North American companies now have a local, as well as an overseas market for products specifically designed to offer methods of protection such as the Ex-e method of protection. More detailed information is available from Killark (faq pages no longer on their website, but see Killark hazardous location pages or review a copy of their old faq information (Killark 1997 faqs).
