2 wire start conductors with power conductors

[electrofelon]

Can the generator two wire start conductors be run with the power conductors? What type of circuit conductors are these?

They would have to be 600 volt rated, and Generac is the only manufacturer that I know of that allows them to be run with the power conductors. Cummins and Kohler require them to be in a separate conduit. Alarm wiring can also be in the same conduit.

Is there an NEC issue or is this just manufacturer instructions?

To answer that you would need to know if the start circuit is a Class 1 circuit or a Class 2 circuit.
Given that most of the start circuits I have seen use the generator starting battery as the control power, it would be a Class 1 circuit and could be mixed as long as the control circuit conductors have an insulation equal or greater than the voltage of power circuit.

Manufacturer instructions which are required by the NEC to follow.

Yes I didnt word that well, I am aware 110.3(B) (probably) requires instructions be followed. I should have said, "Is there another section besides manufacturer instructions"

I am sure if it is listed that way its not allowed.

I've seen every kind of wiring done that does not meet manufacturer specs and never a problem from it, like not even once.

Not advising, just observing

I take pretty much everything a manufacturer says about anything electrical with a grain of salt..... Or just ignore it.... or dont even read the instructions.

I realize my comment above seems generic, I am talking about generators in particular.

From 2 wire start to RS485, seen them all mixed up on loose THHN along with power conductors, no ill effects.
