G- I must have misled you some where along the line, I never intended to unhook the ground in the breaker box. All plugins in the house are grounded, and the ones that are close to water are GFI, the way they should be. They will not work unless they have a ground and wired properly. I did ask an electrictian friend of mine, last night, about the problem. He said GFI's just act stupid some times, but he thought when the transfer switch checks the new incoming power (generator), to see if it is better than the inverter, it confuses the GFI and it trips. He checked to see all ground, neutral, and hot wires were correct and they were. When he put a meter on the system, when everything was off, it showed nothing, except the power all GFI's pull to monitor with. He says it's OK to run as is, because everything is grounded, fused, bonded and GFI's where needed. I did call the Aims company, and they said they had never heard of that, but they also said most generators do not have GFI's. They also said this was a new transfer switch, and maybe they had not taken in to account for generators with a GFI. At any rate, I feel safe in running it the way it is. Thanks, BEAR
