Power Limited Circuit Cable Form 3

That makes sense when talking about power limited circuits.

Power limited circuit cable form 3.

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

Wiring is it power limited or non power limited. For lv what you are asking about is class 2 power limited circuits which according to the nec means voltages of less than 30 volts and power of less than 100 va. They are considered to be a special condition other than a normal power circuit. If the power source is power limited the circuit is power limited.

3043a multi conductor 300v power limited tray cable. Class 1 2 and 3 circuits are classified as remote control signaling and power limited circuits in the national electrical code nec. By itself wiring does not show if a circuit is power limited or non power limited. What i am asking about is when power limited is part of the cable description.

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. The wiring has to be good enough for the type of circuit. 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.
