Zone Classification

Helpful Hint

Although zone classification provides an alternative to classification by division, the most significant aspect of the alternative is in the different protection methods that are available. The wiring methods are not very much different. However, because the highest risk areas of a Division 1 area are treated separately as Zone 0, and wiring is severely restricted in Zone 0, the remaining areas of Division 1 (the Zone 1 areas) may allow somewhat less rigorous protection methods than would be required in Division 1.
