Class 1 div 2 group d

[BasilRW]

If you have a HPS light fixture in a class 1 div 2 group d location and the fixture is rated for a class 1 div 2 location but is not factory sealed does it need a seal at the fixture or just at the boundry limits?

Assuming the luminaire is otherwise properly installed in the Class I, Division 2 location, no additional enclosure seal is required. This would be analogous to any simple terminal box.

The identifying/marking requirements for luminaires can be confusing for Division 2 but, if the luminaire is already marked consistently with the location, the application is pretty straightforward.

I thought so but i feel like ever time I come across an answer in the Code Book it sets me off in another direction and so it confusses me some times.
