Happy to. I don't have more pics as it's all closed up, but can explain. I'll assume a 30amp trailer install.
A 120V automatic transfer switch has 3 thing going to it:
1) Input source A (default)
2) Input source B
3) Output
It automatically switches to whatever input source is powered. If both A and B are powered, it defaults to A.
Input A is the 30amp trailer power input.
Input B is my GZ
The way to install this is to locate the trailer input wire (big orange 10 gauge romex). The power center will be fed by this big orange wire at its backside.
Idea is to cut said big orange wire. The feed side goes to input A of the transfer switch. The other end of the wire that goes to the power center will install to the output side of the transfer switch.
Note that this 10/3 gauge wire is super stiff and hard to work with. You may also not have enough slack in the line and have to add another segment. I removed the original line from the power center, fed to auto transfer switch. Then added a new ~3' segment of 10 gauge romex for the auto transfer switch output to power center.
Now get an extension cord or suitable wire, to install to input A of the transfer swtich. This will now plug into your new GZ (or any other 120V source like an inverter or genny).
One more detail. The specific transfer switch I used has a 30 second delay timer meant for generators such that it can stabilize its output before it switches. The manual tells you how to disable this by jumping points on a circuit board which I did.
