yes, it would (possibly) work, but you’re likely to run into quite a few safety-related issues outside of using the suicide cord. the fact that you’re probably injecting power downstream from any RCD units or even any basic current breakers, leaving you open to electrocution, or worst case, fire. the other issue is if you dont isolate your home from the grid before doing thus, then when the grid comes back (and your generator is still… generating) there’s likly to be a loud bang and a dead generator, let alone the risks you put on any workmen who are working on the lines they are expecting to not be carrying current.

TLDR; unless your hourse is specifically wired for this, and you have the necessary protections in place, just use an extension cord and plug your fridge directly into the generator. 🤷
