6000xp and transfer switch

What gauge wire did you use for GRID? The manual states 8 AWG but, a 50A breaker usually requires 6 AWG, does it not?

I too have a 50 A breaker in my main panel tied to GRID. Charging from GRID works fine other than a hum that occurs when the changeover occurs from GRID back to inverter on a couple of devices. These devices are two battery backups that contain low impedance transformers in them. Other's have noted a similar hum and there are a couple of threads on it.
Wire size and breaker depends on the loads connected.
If inductive/motor loads are the reason for the breaker size, the breaker can be 125% of the conductor rating due to nuisance trip prevention.

I used 6 AWG for inverter to transfer switch and 6 AWG for main panel to inverter. I did have some difficulty getting the 6 AWG ground and neutral wires to fit in the bus bars as I had put ferrules on them
 
I have a ProTran2 10 circuit manual transfer switch and use it with the EG4 6000XP. Originally, I had the manual transfer switch wired up to only 120 volt loads on my subpanel and a couple of 120-volt loads on my main panel. For those circuits with no Arc Fault Breakers, everything worked fine. For those circuits with the arc fault breakers, yes, they would trip when the power was coming from the 6000XP. These breakers are overkill to me (I live in the country but most electricians wire things to the city code). So, I just lived with it. The only pain is if I switched those circuits back to the grid, I would have to reset the arc fault breaker in the subpanel.

Fast forward, I now have changed the circuits such that I power the sub panel entirely, a pool pump, the AC, and the AC blower. I also have the dishwasher and the microwave on two 120-volt circuits, but I rarely use them. If I do use them, I do have to reset the arc fault breakers in the main panel. So, I really don't have much of any issues with it now.
