Remote Control in Class II, Division 2

[mb123]

Could anyone point me to some information as to what is required for remote control systems located in a Class II, Division 2 environment? About the only thing I have been able to find is in 2014 NEC 502.150(B), where it seems to primarily bring out enclosure requirements. Because these systems create electrical power from an RF signal, do these systems need to be considered as power generating devices needing any sort of intrinsic safety/simple apparatus requirement? Should the transmitter be limited to 25mW per the definition of a Simple Apparatus, 504.2?

Thank you in advance!

You found the correct Section and answer. So, unless you want to jump through all the hoops required by intrinsically safe (IS) or nonincendive (NI) systems, (NI is sufficient in Division 2) you have to use the wiring methods of Section 502.10(B) and enclosures of Section 502.150.
