When setting up explosion-proof lighting systems, following stringent wiring guidelines is crucial for ensuring safety and adherence to standards. Here’s a clear, concise guide for executing this task effectively.
1. Steel Conduit Wiring: Use steel conduits for all wiring to prevent any cables from being exposed. Where connections are made, employ explosion-proof junction boxes to maintain the integrity of the setup.
2. Explosion-Proof Flexible Conduit Wiring: When connecting junction boxes to lighting fixtures, use explosion-proof flexible conduits. Cables should be routed internally through these conduits to maintain safety standards.
3. Wiring in Areas with Lower Hazard Levels: In locations with a lower risk of explosions, it’s permissible to use sheathed cable wiring. However, ensure that these cables meet explosion-proof criteria. When passing the cable through the lighting fixture’s interface, seal it with a compression nut to maintain the explosion-proof standard.
