Generator -> eg4 Chargeverter in garage for battery bank charging
I have a portable suitcase style inverter that has 30A and 50A outlets. Two of them can parallel to provide 12000 running watts. I have an interlock kit on my panel and 30A inlet - I can comfortably get by on 5500 watts with 7200 watt spikes (hairdryer, tea kettle, coffeemaker)
I’d like to install a 30A generator inlet in my backyard (where my natural gas line is) run 100’ of 8 awg cu to my garage and have a 30A twist lock outlet in the garage- near the Chargeverter
Now in the past (during and after hurricanes) I’d have a 100’ gen cable running along The side of my house, in the garage door side door window and then twist lock the eg4 Chargeverter right into that 30A 240v gen cord -
Now my question is anything I install becomes premises wiring right ? So now my 30A twist lock (that’s powered by the backyard outside gen inlet ) has to be gfci protected right? Or is there an exception (doubt it)
So I could install say a two space disconnect(or subpanel) and put a two pole gfci in there to protect the generator feed - then out of that pop of a 30a 240V twist lock the eg4 Chargeverter requires
The gen is N-G bonded at the unit it’s a tri fuel Westinghouse that’s 7200 running watts on natural gas.
Am I overthinking or under thinking?
Separate thought - say I have that 30A inlet in my garage powered by the gen outside - what if in a pinch my inverter failed and I wanted to use a short gen cord from the garage twist lock outlet to the panel interlock kit inlet - I’d unbond at the gen (n-g bond at service equipment where interlock is installed)
Any violations of art 702 or other ? Worst case I just use the long gen cord for this
