The chapter focuses on electrical equipments required for a division 1 and division 2 locations. For several electrical equipments, individual components should be explosion-proof rather than the enclosures being purged or pressurized. However, in the case of Divison. 2, the electrical equipment for ...
Primary emphasis is on the use of general-purpose enclosures and precautions against excessive surface temperatures and sparking of rotor bars and enclosure joints. The Guide also provides guidance for maintaining the life-cycle integrity of motors in Division 2 locations. Existing codes and standards,...

material that must exist as a finely divided solid of 420 microns (0.420 mm) or less. This will allow the dust to pass through a No. 40 sieve. Just as inClass I, Division 1 and 2, the subdivision ofClass II into Divisions 1 and 2identifies the likelihood that there is an explosion ...

The Pepperl+FuchsBebco EPS Type X purge system reduces the classificationwithin the protected enclosures fromDivision 1 to non-hazardous. General-purpose equipment can be operated within theprotected enclosure. Type Y Purge System The Pepperl+FuchsBebco EPS Type Y purging systemreduces the classification...
but this time with a 6V bias on the input signal. Notice how the output waveform is no longer clipped at the thick grey 0V line and has been shifted up. (Ignore the misleading graph scaling, the AC voltage is basically untouched. Notice how the voltage-per-division boxes are stretched ...
Within the NEC you can use zone rated enclosures for a process area in lieu of division rated enclosures but you cannot mix systems. In a like manner, compliance with the NEC suggests applying the proper zone rated enclosures, etc. As dpc mentioned, if you need to modify a NEMA 7 enclosu...
