To me it looks like a through the wall extension cord, I guess it might be suitable for a very small cottage where everybody lived, ate. worked and slept in the same room.

Wow, are you going to buy a bunch of extension cords and run them all over the house every time the power if out? Personally I would not bother as it is not convenient.

Do the setup where you back feed a double breaker with a lockout kit on your main panel. Easy and you have limited power for the whole house. you might have to shut off a few breakers for equipment with a huge current draw, but you have lights and power for appliances every where.

One thing I did, and consult a licensed electrician before attempting, was I put a light fixture over the transfer switch , fed off the gen feed before it hit the panel.

As soon as I get the generator running, that light comes on ( I use a LED for low power consumption) and when I go to the basement to throw switches I have light going down the stairs.
Excellent idea! I'll have to copy that when I wire up my transfer switch kit.

Inside though . At least not through a window or door, which would be very appealing in cold weather

...........and fed through a door or window, letting in critters, insects, water

Just exploring simple and cost effect options

In an emergency situation, extension cords running in the house are necessary options

Thoughts on this kit?

It's just through the wall power distribution.. 30A connector generator size to 6 outlets. Better than a cord for situations where a cord is not ideal. Someone will have to reply about the NEC on this, it's not a "transfer switch" and technically power from the generator and the grid at the same time, not that you'd use it that way.

What gauge wire is typically used for a portable generator (5k) remote 220v plug in?

Or does it also depend on the length of the run?

I watched alot of Youtube videos, and they all seemed to use 10G

Would 8G ever be needed on something less than, say 50 feet
Yes. Depending on which ampacity chart you refer to, 8ga would be called for at either 10ft or 20ft. Most 30A generator hookup cords are 10' for a reason. You can't place your generator closer to the box?

Thats a 30a inlet so you would need minimum 10gauge

Here's my setup use a 6500watt lp generator have a lp cast iron stove gas logs for temporary heat, can run the fridge, electric water heater, some lights, well pump and a 5k window ac in a bedroom not at the same time. Hook the generator outside with a quick connect hose and a short cord to a weatherproof 4 wire male plug. Have a 500 gallon lp tank and only use it for the cook stove and cast stove.

if you use #8 on that PLUG you might have trouble connecting the wire....It might be too thick.

I need to look and see if my generator has a 3 or 4 prong connection

The small load centers are not that expensive -- no extension cords inside ... safe and quick when you need it.

IANAE, but I have not run into any panels that will not accept SOME tandems. May be a limited number. Last time I needed to add tandems, the limit was 4 and that was exactly what I needed !
This was my case. My LC has 28 slots, but the cover states "maximum 40 circuits". I popped in tandems in to give me the space for the generator feed with interlock, EV charging, and a extra circuit for the garage.
Looking at these again.

Wondering how many watts and circuits

Sump pump, fridge in kitchen, freezer in basement, fridge in basement, and furnace?
Google has some ideas on those numbers. Sump pumps vary with size but your average one is about 6 amps. Fridge and freezers are 5-7 amps. Gas furnace is just 5 amps or so running. All loads have an inrush requirement of up to 3x their running amps. a 3500W generator would keep these items running. A 2k generator could probably keep the furnace and refrigerators running but the startup draw of a sump would be too much.

... <trimmed for space>

Anyone ever use one of these?

Thoughts on this kit?
I think these are excellent ideas for keeping it very simple. The trick though is to make sure you can plug your furnace in. There's been some debate on if it's legal to put a cord on a furnace and plug it into an outlet. IANAE and the chat always revolves around "it depends". Some say they've never had an inspector blink an eye. Others can quote codes that can be interpreted as prohibiting it. These generator switches wire inline with your furnace and provide a way to feed the generator while it remains hardwired. These kits are also great if your generator has a bonded neutral which many are because you can order it with or without switched neutrals.

Wiz, you need to get out more. My last house had twice that many 240 breakers. 3 heat pumps + air handlers, 1 AC + air handler, two ovens, range top, two water heaters, hot tub, one mini split, 3 branch circuit breakers to feed other subpanels.
How big is your generator? With only 5500 watts I don’t run any of the 240v stuff. Gas fireplace for heat and gas stove top for cooking. Heat pump is a no. Would love to have a bigger setup that runs off the natural gas but not in the cards right now.

OP, if you cannot install the interlock, a proper transfer switch would be prudent. Reliance makes a 30A 6position and a 50A 10 position that seem popular.

I bought the 50A 10 position (model 510C), used 9 positions and left the spare capped in my panel “just in case”, wired with 8ga to a 30A generator inlet from the same company. My wire run was about 42 feet, therefore the 8ga. And it didn’t cost much more. Also the inlet was rated up to 8ga, you will want to verify this before purchasing.

All this to a 30A 4 prong outlet on my generator, which can only provide 7000 running watts and has a 30A breaker. I use a 25 foot cord from the generator manufacturer (not the cheapest way to go, but not bad on sale) with molded ends.

I say all this to say that all of the parts to install this are over-the-counter items and can be shipped to you from any number of suppliers.

For me, this works. If I had to do it again, I would install the interlock. I would have looked into the generlink (above post) if I knew about them at the time and if they were allowed in my area.
