I was helping a disabled lady during a power outage this past winter, who had just bought a generator and needed help putting it together. It came with sufficient cabling to run the hot end through the sliding door on her deck, but she instead wanted me to rig up a suicide cord for her so she could plug multiple things in, and not have the door cracked open. I promptly refused; in retrospect, I should have at least suggested she turn off the breakers. The safety of the lineman restoring service to the area would probably have appreciated it.
Would love to have the generator, but without that cord! If it were mine it would probably receive a set of solidly mounted IP 44 Schuko sockets and maybe one blue CEE to provide temporary power in remote locations and run portable appliances.
I've been pestering the local reps to cough up a 100/30A transfer switch, not so you could run an entire 100A sub panel on a 30A generator cord, but so you could leave on the refrigerator and maybe a couple lights, but still have a true 100A during normal operation strictly for the safety of the linemen! -guess I gotta go into production.
