When
specifying cables for field installation in raceways, does anyone have any best
practices for keeping Class 1 600V rated cables separated from Class 2 300V
PLTC and communication cables. The projects I am working on use bulk 24VDC
distribution which drive the us to using standard 600V rated TC but most of the
instrument cable and ethernet cables fall into the PLTC realm. My understanding
of the NEC 725 is that I must physically separate these cables even though they
are all 24V. Do I just need 1/4" separation in cables or should I be looking
at barriers or a whole differnent tray system? Perhaps I should find a way to
use all 600V rated cables?
