115 circuit in a low voltage condiut

[Michael.l.smith]

Can you pull a 115 volt fire panel feed circuit in low voltage conduit going to a PLC?

low voltage

low voltage

is the low voltage wiring insulation rated for 115v or more.

 

[iwire]

Most likely no regardless of the insulations rating.

is the low voltage wiring insulation rated for 115v or more.

It's a Honeywell low voltage wire which complies with NEC article 760 class 2

Its not type of the wire, that Class 2 on the cable jacket means its suitable for a NEC Art 725 Class 2 circuit. What determines if the 120 volt conductor can be in the same racewith the limited energy (not low voltage) is the type of limited energy circuit it is, this is determined by the power supply. Most are class 2, and see 725.55(A) and forget 300.3(C)(1). If limited energy is a article 725 Class 1 circuit, then it can be with the 120V as a Class 1 circuit is wired using a chapter 3 wiring method.

Would not the lo-voltage wire need to be rated 600 volts, not 115, as the insulation on traditional building wire (NM, THHN, etc) is 600 volts?

 

[tom baker]

The insulation of the limited energy (its not low voltage) cable or conductor must be adequate for the system voltage and if its an Art 725 Class 1 circuit, then 600 volt rated, to be in the same raceway or enclosure with the 120 V circuit.
