Power-limited wiring may be combined in the same cable or raceway as which wiring?

Explanation:
Power-limited wiring is designed to carry only limited energy, keeping voltage and current within safe, low levels. Because of that safety limit, it can share the same cable or raceway with other conductors that are also power-limited, specifically Class 2 wiring. This keeps installation simple and cost-effective while staying within the same energy-constraint category. Mixing with higher-energy wiring would violate safety and codes, which is why the pairing is with Class 2 rather than the other classes.
