It makes you switch off the main breaker and then locks it off to allow you to turn on your back feed breaker, making it impossible to have you backfeed breaker and main breaker on at the same time. I have my backfeed breaker wired to a receptical that I can plug a 220V extension cord in to from the generator.
That’s exactly what I’m looking to do.
The other thing is our home since we got rid of the kids is small, the mini split, fridge, freezer, and assorted other loads have been taken into consideration, short of both food units, the ac, washer/dryer and microwave all lighting up at the same exact time, this will handle the load.
It might be an 8,000 watt unit, but it is rated for 10,000 start up, at 3x for just our ac it’s still at 3600 watts.
Fridge and freezer are 700 running, so figure 4200 for both if they start at the same time.
Lighting is minimal, especially with LED bulbs, plus the sound is enough advertisement, don’t need our home looking like a Christmas miracle.
