sealtight? waterproof? if i look in my truck boxes for a fitting, what do i look for? what qualifies in the class 2 div 2 zone?

Cindy,
Standard sealtight and fittings are fine for Class 2 Div 2. In Class 2 we aren't trying to contain an explosion like we are in Class 1, all we are trying to do is to keep the dust out of the electrical equipment and keep the electrical equipment surface temperature far below the ignition point of the dust involved.
