Successfully tested powering my home with 30A ProPower and a generator interlock

Is this a Siemens meter base? I have been looking for a good new meter base, and this matches what I am looking for.

Just wanted to chime in and say I got something very similar to the OP’s setup and it works great. Instead of 30A I opted to get a 50A SS2-50 inlet for future proofing. Requires an adapter you can find off Amazon to L14-30P to SS2-50R.

Similarly, the GFCI trips on the truck end and the electrician disconnected the ground from the inlet to the panel, at the panel side. He felt comfortable doing it since the house side ground still keeps everything inside safe, and the truck GFCI still protects the cable run (he was more concerned about accidental damage to the outdoor cabling run).

I had wanted to do it the “official” way with the Generac GFCI sub panel but it was way too impractical. For some reason just lighting and appliance and bedroom outlets were spread across 15 different breakers so even with tandem ones it was a stretch.

You have an mechanical interlock & breaker inside your main panel then? Which is what the generator inlet is wired to?

That is what I have but since mine is grounded I received the Truck GFCI tripped error.

That is correct, they installed a 200A “main” breaker on the inside panel (the meter has the official 200A breaker), interlocked with a 60A breaker in the panel. The inlet goes to that 60A breaker (got a SS2-50P inlet).

The ground from the inlet was disconnected in the panel side, it’s usually tied to the ground bar in the panel. This resolved the GFCI trip.
