What type of Fiber Otic can be used in the different classes (class 1, clas 2) and divisions (division 1, division 2) of Hazardous Area Classifications?
From 2008 NEC:
<i>(F) Hazardous (Classified) Locations. Cables installed in hazardous (classified) locations shall be any type indicated in Table 770.154(E). Cables shall be sealed in accordance with the requirements of 501.15, 502.15, 505.16, or 506.16,as applicable.</i>
These are listed in the table:
OFNP
OFCP
OFNR
OFCR
OFNG, OFN
OFCG, OFC
With that said, 500.8 (F) requires the following:
<i>(F) Fiber Optic Cable Assembly. Where a fiber optic cable assembly contains conductors that are capable of carrying current, the fiber optic cable assembly shall be installed in accordance with the requirements of Articles 500,501, 502, or 503, as applicable.</i>
Therefore, if you use any with a "C", the fiber cable will be treated as any other current-carrying conductor (OFCP = Optical Fiber <b>C</b>onductive Plenum etc)
