Article 500-516 Hazardous Locations

[Jwelker]

Our company has to install devices in a Class 1 Division 1 area that require 12-24VDC power to operate and utilize between 200mA and 600ma of current. Power supplies will be located in the non-hazardous areas but conductors will be installed to devices in the Class 1 Division 1 area. What devices do I need to install to protect these current carrying lines? Anyone have any specific products they have used for this application? I've looked online but unsure of what device to use at this point. Thanks for any help.

I would suggest getting a qualified engineer on board, have a complete set of drawings and materials list, area classification. Some locations will require permits and inspections. In WA to do this work your company would have to be an electrical contractor, with licensed journeyman or hire an EC to do the work.
From your post you are unsure of requirements, this is not an area to be a DIY
