Have an existing building I'm struggling to get all the pieces and parts in to add an ATS (Actually two ATS, one for normal loads and one for emergency). Making sure I'm not crazy.
I have a 480/277 3 phase generator. Stepping down to 208/120 3ph at the building. So there will be a transformer in between the ATS and the Generator. Is there a way I'm not seeing that I can use the transformer primary over-current protection to protect an ATS? It looks like I need to add a fuse or circuit breaker between each ATS and transformer. Thanks for any input.
