Zone 22 equipment

[Dilva]

Question in zone 22 (dust) is it allowed to install non-certified equipment, however it meets the requirements of industrial equipment such as IP 6x, surface temperature, non-sparking (junction box, switch, luminaires)If possible, what standard does it indicate?

The NEC, NFPA 70, requires the equipment installed in a Zone 22 location to be listed and marked as suitable for the location. This is a bit more restrictive than the NEC requires for a Class II, Division 2 location.

 506.20(C) Zone 22.  In Zone 22 locations, only equipment listed and marked as suitable for the location shall be permitted. 

Exception No. 1:  Apparatus listed for use in Class II, Division 1 or Class II, Division 2 locations with a suitable temperature class shall be permitted. 

Exception No. 2:  Pressurized equipment identified for Class II, Division 1 or Division 2 shall be permitted. 

Exception No. 3:  For Group IIIA materials, equipment listed for use in Class III, Division 1 or Class III, Division 2 locations with a suitable temperature in accordance with 500.8(D)(3) shall be permitted.]
