I was reading the following thread, but I could not find answer to some of my questions
1. Generac classifies the N1, N2, T1 and leads 23 and 194 as class 1 signaling circuits.
2. Generac gives reference on page 8 of the manual for the ATS stating that "AC and DC circuits are permitted to occupy the same equipment, cable and conduit as per NEC 300.3(C)1."
Q1: 300.3(C)1 and article 725.48 does not mention anywhere the word "conduit", it mentions cables, cable trays, enclosures, raceways but not conduit. Do we just assume they include conduit? Some define conduit as a type of a raceway but I could not find any reference to this.
3. 725.46: Class 1 circuits need to be installed using wiring methods of chapter 3, but Exception 1 and 2 allows them to be also installed using 725.48 - 725.51.
4. 725.51(B) Ampacity adjustment only when 10% or more of other conductors.
Q2. As per #4 I would not need to adjust ampacity of the Load feeders from the ATS (250 MCM Copper) while I have the #14 thnn conductors from #1 in the same conduit, if I read this correctly? The question remains about the conduit and if article 725.48 means conduit as per Question 1.
What are your thoughts?
AC/DC wires in same conduit for Generac generator
I have been installing generators for close to 8 years. I figure somewhere in the neighborhood of 1,500 generators. The company has existed for 20 years prior to me. I have always run a single conduit from the ATS to the generator, and pulled the feeder and control wires all in the same conduit...
