Class 1 Div 2 Seal off requirements

[Gategator37]

Do T8 3 lamp fluorescent fixtures located in a Class 1 Div 2 area require seal offs? I know that 501.15(A)(1) states that a seal off is required for arcs, sparks, or high temperatures, would this be considered one? I would say know, but am unsure and would like to be better safe than sorry.

Thanks a lot.

seal offs are required when entering or existing the classified location. I don't believe you don't need a seal off for every fixture. The fixture has to rated
for classified location.

Thank you. That's what I thought but was unsure.

You were citing rules for Division 1. Make sure the luminaire is suitable for Division 2. See 501.130(B). If it isn't, seals won't make a difference. Don't confuse them with boundary seals.
