Hello, dear sea friends! Class A explosion protection, Class B explosion protection, Class A workshops, Class B workshops – how are Zones 0, 1, and 2 distinguished? Are there any guidelines or markings? I hope everyone will do their part, contribute as much as they know, and bring up whatever is relevant for discussion, so that the issues can be thoroughly addressed
Zones 0, 1, and 2 are zones for explosive gas environments; in the GB50058-2014 Code for Design of Electrical Installations in Explosive Atmospheres, section 3.2； I’m not sure what you mean by the classification of Class A and Class B workshops as per clause 3.1 on explosion-proof requirements in the construction regulations; after all, I’m also new to this field, so let’s learn from each other
This kind of knowledge is related to standards and specifications; it becomes clearer only when faced with actual situations in a factory. Therefore, it’s difficult to explain thoroughly without expertise in electrical engineering. I’m not sure if any teacher can help clarify this
Reference can be made to GB T 3836.1-2021 Explosive atmospheres – Part 1: Equipment – General requirements
