According to the NEC, non-power-limited circuits may operate with voltages as high as?

Explanation:
Non-power-limited circuits are allowed to carry higher voltages than power-limited ones, and the NEC sets the maximum voltage for these circuits at 600 volts. This means circuits in this category can operate up to 600V, which is why that option is the best fit. The other voltages shown are common values for different uses, but they do not represent the NEC’s upper limit for non-power-limited circuits.
