Explosion Proof Junction Box and Panel, Engineers Should Understand!

Every electrical and Instrument engineer must understand about explosion proof junction box and panel if he will work for hazardous area (oil and gas). That is because he will face areas that have high risk of fire and explosion.

An explosion proof junction box or panel is serving as a delimiter, while an explosion proof junction box or panel is placed in hazardous area (area that flammable materials exist around) and there is any spark occurs in the junction box or panel then it will not make flammable materials outside on fire, it muffles the spark and keeps inside.

Explosion Proof Junction Box Material

There are options in material of explosion proof junction box. They are metallic and non-matallic. The metallic explosion proof enclosure is generally made by aluminium, stainless steel 304 or 316, cast iron materials and more. When non-metallic, the most used is GRP (Glass-fiber reinforced polyester) and other non-metallic materials could be other options according to supplier’s offers.

Explosion Proof Tested Junction Box

Explosion proof enclosure has to be accurately made. To ensure a junction box can be used in hazardous environments then this should be made with reference to the standard. If in North America, several testing laboratories that are recognized by government and international such as FM, UL and CSA have their respective standards used to test electrical equipment for hazardous areas. So if your project is using North American specification standards then make sure the equipment you use in the hazardous area has a testing mark of FM, UL or CSA. Whereas in Europe, testing laboratories use EN 50.018 standard for explosion proof apparatus.
