so if i run lighting to a pump house in an oilfield that is classified class 1 div 1 or class 1 div 2, then those ckts have to be intrinsically safe?
i never saw an intrinsically safe thhn..i have seen shielded cables and explosion proof fittings and enclosures...
the question came up because an inspector is requiring INTRINISCALLY SAFE CKTS at a refuleing station!
some of the control and POS is intrinsically safe but the rest of the building and ckts are normal ckts...these are in unclassified locations...
what could he mean?
here is the exact quote:
"COMPLY NEC 514.11 AND 514.13/SPECIFY ALL CIRCUITS INCL INTERCOMS, LO VOLT CONTROLS, COMPUTERS, INTRINSICALLY SAFE, ETC)."
these articles have nothing to do with intrinsic ckts...that i could tell..
thanks for the replies
