I want to use this cable to supply two ac circuits to a remote location in the machine.

Power limited circuit cable form 3.

They are considered to be a special condition other than a normal power circuit. What i am asking about is when power limited is part of the cable description. You can wire class 2 circuits with class 2 cable or any of its substitutes permitted by table 725 61 a depending on the condition of use. Class 1 2 and 3 circuits are classified as remote control signaling and power limited circuits in the national electrical code nec.

That makes sense when talking about power limited circuits. By itself wiring does not show if a circuit is power limited or non power limited. Use class 3 circuits when the power demand for circuits over 30v exceeds 0 5va but is not more than 100va chapter 9 table 11. Wiring is it power limited or non power limited.

3043a multi conductor 300v power limited tray cable. If the power source isn t limited the circuit is non power limited. This is a 2 pair 16 awg shielded cable from belden. The nec defines such circuits as that portion of the wiring system between the load side of the overcurrent protection device ocpd or the power limited supply and all connected equipment.

The national electrical code nec class 2 and class 3 covers remote control signaling and power limited circuits covered by chapter 7 in article 725. In class 2 and class 3 systems either the voltage or the current depending upon circuit design is limited to a level that will not cause a fire and under. If the power source is power limited the circuit is power limited.
