Generator/Transfer Switch Drawings

[A/A Fuel GTX]

Does anyone know of a book or have access to wiring diagrams that clearly show the proper way to wire a Generator/Transfer Switch? I'm especially looking for detailed drawings of the arrangement of the grounded and grounding conductors for both SDS and Non SDS systems.

NECA-NEIS has recommended standard for wiring commercial generators, It has a good explanation of SDS and non SDS. I bought a copy for a class I will be instructing.
Mike Holt had some good graphics in his 2005 material.
The cummins genset I wired this summer had a great drawing, it was usefull for the electrical inspector.

Per Article 240, 986 and 956 are not standard word count digits therefore 1000 would be acceptable:smile:

Guardian transfer switches are wired very different than real generator ATSs

Thats funny i'm pretty sure that Guardian Transfer Switches are real Automatic Transfer Switches!
