The difference between explosion-proof lighting distribution boxes and explosion-proof power distribution boxes

WithWhenWeatherTheseTwoVariousDistribution BoxIsConnectinOneRiseUse的，Explosion-proof power distribution box And Explosion-proof lighting distribution boxShouldClassOpenWiring Layout。

Explosion-proof lighting distribution boxes are mainly used for power distribution and lighting control. Since explosion-proof lights have lower power ratings, the load on lighting distribution boxes is smaller than that on power distribution boxes. The total current is generally below 63A, and the single output current is below 16A.。They are generally single-phase powered, but three-phase power can also be used according to actual needs.。

Explosion-proof power distribution boxes are mainly used for starting, running, and stopping control of motors for fans, mixers, oil pumps, water pumps, or other machinery such as mold temperature controllers and chillers.。They control relatively high-power motors with larger loads.。The total incoming line current is generally above 63A.。

according toUse Environment，Explosion-proof Electricalindustrydivided intoIVarious And IIVarious，IVariousIsIndexCoal MineundergroundEnvironment，IIVariousIsIndexCoal MineundergroundLocationsDemand的Explosive Gas Or DustEnvironment。When selecting, Category I requires a coal mine safety certification (MA certificate), which requires special attention.。

Category II environments are further divided into IIA, IIB, and IIC based on the ambient gas. Except for acetylene, hydrogen, and carbon disulfide which require IIC-type explosion-proof distribution boxes, all others can use IIB level.。

Based on the duration of flammable gases and dust present at the site, they are further subdivided into Zone 0, Zone 1, Zone 2 and Zone 20, Zone 21, Zone 22, corresponding to explosive gas atmospheres and dust atmospheres respectively. Explosion-proof distribution boxes are not commonly used in Zone 0 and Zone 20; we mainly focus on Zone 1 (Zone 21) and Zone 2 (Zone 22) conditions.。Except for pressurized (Ex p) enclosures which use different explosion-proof levels in Zone 1 and Zone 2, flameproof (Ex d) explosion-proof distribution boxes can be used in both zones.。
