I would like to add a gen-tran manual transfer switch to my electric panel but I live in a condo where the main panel is in an external meter room and my only interior panel I assume is a subpanel.
The bond screw in my panel has been removed which tells me that it is in fact a subpanel.
Now, the manual transfer switch has a ground cable but I do not know if it needs to be connected to the neutral bar or if I should connect it to a screw directly on the metal case.
Which is the safe and correct mounting point for that ground cable? Thanks
