照明電纜必須完全導管安裝喺防爆區域

使用外部導管增加電纜嘅決定唔會影響現場嘅防爆安全措施. 喺指定為防爆嘅區域, 標準係使用鎧裝電纜, 從而繞過了對額外管道的需求.

The critical aspect is to ensure airtight sealing at the point where cables connect to junction boxes, employing explosion-proof cable glands. A key standard to adhere to is routing only one cable through each gland, avoiding the passage of multiple cables through a single point. As for external cables, adding conduits is unnecessary provided their outer casing remains undamaged.
