There is a familiar generator company that supplys a whip for connection from the transfer switch to the generator. This whip contains both power and control wiring from a class (2) transformer. Chap. 725 nec says only functionally associated equipment of a class (1) is allowed to share the same raceway with power cables. The transformer is located in the generator,and is 230/12v.and looks to be 40 or 50 watts. Any thoughts or is this manufactured whip exemp.
