I want to build a smart outlet using a solid state relay. I also want to keep this project up to electrical code.
So pursuant to NEC 2008 section 800.133
Communications conductors shall not be placed in any raceway, compartment, outlet box, junction box, or similar fitting with conductors of electric light, power, Class 1, non–power-limited fire alarm, or medium-power network-powered broadband communications circuits.
Exception No. 1: Where all of the conductors of electric light, power, Class 1, non–power-limited fire alarm, and medium-power network-powered broadband communications circuits are separated from all of the conductors of communications circuits by a permanent barrier or listed divider.
Exception No. 2: Power conductors in outlet boxes, junction boxes, or similar fittings or compartments where such conductors are introduced solely for power supply to communications equipment. The power circuit conductors shall be routed within the enclosure to maintain a minimum of 6 mm (0.25 in.) separation from the communications circuit conductors.
My plan then was to use a low voltage divider plate in a double gang box, but how do I connect the high voltage components with the divider there? Can I cut the divider and use PVC conduit to protect the high voltage components? Would heat shrink be insulation enough?
