Can the equipment and devices in Category A factory areas be designed to be explosion-proof?
Thread Content
Everyone: If an equipment production line is installed in an existing Class A area, does it have to be designed according to Class A, or can the electrical control adopt an explosion-proof design? In addition, can the electrical control design in areas with large dust be based on explosion-proof design? Thanks!
Category A products do not necessarily need to be explosion-proof. Those that are not Category A do not necessarily need to be explosion-proof. If an equipment production line is installed in a Category A area in accordance with the requirements of the specification, the design must of course be based on Category A.
After checking the information, this should be designed based on the content of the "Code for Design of Electric Power in Explosion and Fire Hazardous Environments" (GB50058-92). We in Haichuan also have relevant discussions, address http://bbs.hcbbs.com/viewthread.php?tid=362941 http://bbs.hcbbs.com/viewthread.php?tid=364181 Hope it can provide reference.
It can’t just be explosion-proof, it must meet the explosion-proof grade. Please check the specific grade classification requirements.
Category A and explosion-proof are not the same concept. Category A area is not equal to explosion-proof area.
