Not quite.
If it's a 220V generator, it has to be plugged into a 220V outlet (electric dryer or electric stove, most likely).
I had to do a field-expedient splice of a generator last winter during an ice storm, and connected it via the service panel in my garage.
Most home generators have a few 110’s or a 220.
Common sense would tell you plugging 220 into a 110 would not be prudent.
Pulling the Meter costs nothing, it unplugs like any other device. My brother in law is a Master Electrician and he showed me that little trick. That’s what they do.
Those big switches are expensive, just for convenience, and I question the reliability. Most generators don’t put out the smoothest power. Nothing is safer than pulling the meter. If you have a digital meter that may be another story.
Unplug everything you have no exceptions, then plug 110 into an outlet that side will be energized, then repeat the process on another outlet on the other side from another 110. Your amps will be limited of course by the quality of your extension cord and the outlet you plugged into. These days you’d be surprised by all the little power eaters you have in your home.
Of course you still have to watch you amp usage. No 2000w hair dryers, garbage disposer, and microwaves. In a crisis only the women worry about that. That is the one big advantage of gas like I have, the stovetop, water heater, and furnaces ect. are all gas. The refrigerator and furnace blower are my biggest ongoing amp users and that is periodic.
Most generators will zap many electronic devices. I’ve found generators that vary voltage and phases by 10%. Sometimes because they don’t run the correct RPM.
My first and best generator was a Honda 3000w inverter. Perfectly clean power, and it kept my household(4+2inlaws) humming for a week. It was quite an education for the clan, figuring out their electrical footprint.
