1. It depends on how the boundaries are established but basically a seal within 10' of emergence from grade and no other fittings between it and the boundary will do. 2. Burial depth(s) are still controlled by Section 300.5. 3. As long as the junction box is located outside the classified envelope it can be any Type otherwise suited for the .
3. Explosion-Proof (Ex d) Junction Boxes. Explosion-proof junction boxes are constructed with flame-arresting materials that help cool down and contain an explosion within the enclosure. This prevents flames or sparks from escaping and igniting the surrounding atmosphere, making them ideal for areas with a potential for explosions.The most important thing for a proper functionality of the equipment and to avoid the spread of fire/explosion is the correct installation of sealing devices next to the equipment to be protected, as clearly indicated in paragraph 13.5.3 of EN 60079-1 / IEC 60079-1, where it is written that "the distance from the nearest surface of the sealing to the housing (or the housing provided for .
The switch (in an explosion-proof housing) activates the remotely-located starter for the motor. The blue line represents the wires to the switch. The orange line represents the wires from the starter to the motor. The junction box below the switch is just a pull box; there are no splices in the box. My question is do explosion proof boxes typically need seal offs on the conduits coming into the box if the conduits are less than 2" in size and the box contains just wire nuts? I see seal offs are required if the box contains switches, outlets or other "ignition sources". Are wirenuts considered ignition sources?
