Pending Code Change Item for 2011
As noted in the NEC Committee Report on
Proposals, 2010 Annual Revision Cycle, Code-Making Panel 14 has
voted to accept a Code change submitted by Eliana Beattie, ISA (Log
#4449 NEC-P14). Beattie recommended adding a new Fine Print Note (FPN)
to 505.9(C)(2), which should help eliminate confusion on the use of
equipment in hazardous (classified) locations.
The new FPN would read as follows: "Equipment installed outside a
Class I, Zone 0, electrically connected to equipment located inside
Class I, Zone 0 may be marked Class I, Zone 0/1. The "/" indicates that
equipment contains a separation element and can be installed at the
boundary between a Class I, Zone 0 and a Class I, Zone 1 location. See
ANSI/ISA-60079-26, Electrical Apparatus for Use in Class I, Zone 0
Hazardous (Classified) Locations."
