Non-power-limited circuits operate with voltages up to ?

Explanation:
Non-power-limited circuits are defined by the voltage they can carry in life-safety wiring, and the standard upper limit for these circuits is 600 volts. This threshold is used by codes to separate circuits that require different protection and installation rules from those that are more restricted in hazard potential. So the maximum voltage for a non-power-limited circuit is 600 V. The other voltages either fall below this limit, which would still be considered within the non-power-limited range, or exceed it and would involve different classifications and protections.
