I am having trouble understanding 725.41 (B).
I am thinking that there is some type of benefit to a circuit being classified as Class 1 unlimited power source.
Benefit such as relaxed requirements. Relaxed from Art. 300 rules.
But I see overcurrent protection, wiring methods, conductors of different circuits in same raceway, number of conductors in raceway. All following Art. 300 rules.
What am I missing about 725 Class 1? Why does this Section exist if it could be covered under Art. 300? These type of circuits have to be used as "remote-control and signaling" but to receive what benefits?
Or, relaxed requirements are not what are given to these circuits.
Why the special classification?
