Descriptive diagram
There are three pairs terminals
Let's designate the left side LINE 1 and the right side LINE 2
The top two terminals connects to the municipal power
The middle two connects to your power distribution panel, this is the common pair
The bottom two connects to your back up power or generator. Don't forget the ground wire, this is for safety and to limit if not stop surges every time a considerable load turn on.
