Does the NEC require instrument stands with transducers, transmitters, etc @ 24VDC and under 1A, to be bonded to the ground grid in a Class I Division 2 area?
Fairly common heavy industry/ petrochem project specification. There is no code requirement for that.... - however, our inspectors want to see the stand - galvanized C6-channel - bonded with #2AWG down to the equipotential ground grid which is a buried #4/0 bare copper and runs throughout the entire Plant - mostly Class I Division 2, C & D.
