I have a 600v 19 conductor #10 tray cable and 2- 300v beldon cables in the same conduit is this legal ?
Maybe, maybe not. It is likely that the rules in Article 725 apply. 300.3(C) even has an informational note that tells you to look at 725.136(A) if the low voltage conductors are Article 725, Class 2 or 3 circuits. There are even restictions on mixing Article 725 Class 1 conductors with power conductors. 725.48...
If I'm reading 300.3 C right, It seems to me that the OP could certainly have 277 volts on any of the conductors right along with 5 vdc. (or less) on the next ...
Is this an Article 725 Class 2 or 3 circuit?More information, the beldon is 300v rated carring a signal between control panel plc's.
Is this an Article 725 Class 1 circuit?The tray cable is used for control (dry contacts) between the same control panels 120v max. (e-stop, alarms, ect.)
