Explosion-proof junction boxes are usually made of cast metal. Its function is to work in an explosive gas environment, even if there is a circuit spark in the box, or some explosive gas infiltrates, a small-scale deflagration will occur under the action of the spark, and the box can withstand, this situation can prevent the junction box Sparks caused by internal short circuits have an impact on hazardous areas of the site.
Explosion-proof junction box wiring requirements:
Customers who use explosion-proof junction box products should know that there are binding posts inside the explosion-proof junction box. Therefore, do you need to use binding posts or terminals when wiring? Are there any specific wiring requirements?
Explosion-proof junction boxes are often used for lighting screw connections in explosion-proof areas. Some customers remove the internal terminal, do not use the internal terminal, and wrap the cable directly with insulating tape for insulation. Typically, internal terminals are used for wiring. If using a terminal, the key is to tighten it. And using insulating tape instead of terminals, after day after day, spring, summer, autumn and winter, the insulating tape may fall off and cause a short circuit accident.
