Class I Division 2 Products & Hazardous Area Locations
Published 28 May 2020
Class I, Division 2″, (or C1D2 for short), products are electrical devices approved for use in a hazardous area or location in North America. They can be manufactured anywhere in the world but, they need to be approved only by North American certifying agencies for use in Canada and the U.S.
The most common among them, for North America, are CSA, UL, FM Approvals, QPS, TUV and other Nationally Recognised Testing Laboratories (NRTLs) listed on the OSHA website.
Manufactures should identify the applicable standards for CLass 1 Division 2 C1D2 for their specific type of products for both “ordinary location” and “hazardous location” required.
The Canadian Electric Code/National Electric Code in the US requires that wiring that enters or leaves such equipment needs be protected by a conduit installation or special cables to protect the wiring system against mechanical damage. (Other than Non-incendive equipment).
Therefore, the equipment enclosure needs to have a provision for the connection of metal conduit or cable glands. This should be considered during the design stage.
