Class 2 equipment is often called what?

Class 2 equipment is often referred to as "dust-ignition proof." This designation indicates that the equipment is designed to operate in environments where there may be a presence of combustible dust. The term emphasizes that the equipment has been constructed in a manner that helps to prevent the ignition of dust particles that could otherwise lead to a fire or explosion hazard.

The classification is part of a broader system used in hazardous locations to ensure that electrical equipment is suitable for the specific risks present in that environment. Class 2 equipment adheres to stringent construction and performance standards that specifically mitigate the risks associated with dust accumulation and potential ignition.

In this context, terms like "explosion-proof," "water-resistant," and "fire-resistant" refer to different characteristics and protective measures for equipment, but they do not specifically address the concerns of combustible dust. Each classification is important in its own right, but for Class 2, the key focus is on the prevention of ignition sources from dust, making "dust-ignition proof" the correct terminology.
