I'd like some feedback on an issue I'm having. I want to upgrade the automatic transfer switch we're using for the substation station service AC feeds. The station service transformers from each bus need to feed into an ATS which should feed into an AC load center panel. In the past, we have let contractors who put in the AC load center panel provide a couple of contactors with AC coils and throw those into a junction box with the two AC feeds wired through them so only one contactor at a time is feeding the load center. It's cheap and dirty; but I'd like to move to an actual ATS switch like you would buy from ASCO or LakeShore.
Can anyone help me with some arguing points against wiring the loose contactors in a junction box and moving toward a real ATS? I don't believe what I'm seeing out there now is the right way to go.
Thx
