what kind of wiring is this?

[tim89s]

I have a 10 conductor twisted pair shielded 22 guage 300 volt cable. The cable is used to transmit voltage and amperage readings from some CT'S on a generator to a power analizer. I have just been told that there is over 400 volts between wires in the cable assemply. I have been told to bring it up to NEC standards. I am wondering how I would classify the wiring. My guess is its a class 1 signaling circuit but there is no overcurrent device. At this time this is all the info I have.

I would classify them as 725.41(B) Class 1 Remote-Control and Signaling Circuits... good for up to 600V and unlimited power output.

Thank you both very much.
