I am a residential electrical contractor in Seattle, WA and have never come across a Cummins generator. A client of mine lost a phase and I found it was lost in the ATS. I told them I don’t have a strong background in Cummins as I’ve always used Generac and found them a technician by calling Cummins directly.
The technicians have been horrible and weren’t going to pull a permit and scared my client off so they asked if I’d be willing to give it a go and just replace the whole transfer switch. I’m confident in following the schematics and everything I’m just unsure of which model to buy and if I’ll have access to everything I need through online distributors or big box stores.
The model number of the generator is 20GSBB-6714A which has been discontinued.
Does anyone have some insight on this subject? I tried uploading a picture of the ATS as I imagine some of you may have an easier solution then replacing the whole ATS. Power comes in on the top of the switch and has both legs present, then the switch says phase A on phase b off.
I appreciate any help on this subject, thank you!
