We are installing temperature switches at the discharge side of pumps in our JP-4 Test Area ( Jet Fuel ). Switches are sealed and rated for Class 1 div 2 . We will mount a hazardous location " C " on the switch and make our terminations there . I say because these are not a arcing device such as a light switch and are sealed we do not need sealoff until the conduit leaves the class 1 div 2 area. The area supervisor thinks seals are required at each switch . Any opinions are appreciated ....
