For reference, during the lead up to the Y2K, there was only 1 brand of transfer switch certified for use in Ontario. It was sold by a company I dealt with for other items. According to the information provided, the use of anything other than an approved transfer switch will result in the immediate termination of power to the home in question. In other words if a utility guy saw a powered home during an outage and they didn't see an approved transfer switch, they immediately removed the meter and would not reconnect it until the issue was proven to be fixed (plus applicable fines and fees).
Also, it isn't a good idea.
As for the 30/50 adapter, it either connects both legs of the 50 to the single one on the 30 - 240 stuff sees 0, or leaves 1 leg open - 240 stuff sees 0. Connecting 2 different sources to make 240 gets into that whole misaligned sine wave thingy mentioned earlier.

Wayne the real problem is NOT if it could be done but why these HOW TO HACK THE house wiring done to code threads should not exit because someone without full understanding of the WHY of wire codes may get hurt or hurt others period because they TRUST some internet forum posting. Sorry, I thought after a dozen posts addressing the legality and advisability, including the original poster acknowledging this, it was ok to just address a technical error that was introduced into the thread. I thought the other horse was already beat pretty darn dead.

Just to make it clear to all members, connecting a power source (example a Portable Generator and even a solar powered inverter) to a Utilities Power Grid can kill some one!!
FYI:
Don’t think that Linemen don’t know that there are people out there that could connecting a generator to their house during a black out. They have safety procedures in place to keep them safe from such people, but again the Linesmen are human and things can go wrong and have.
Also Power Generation and Distribution is not a simple subject and cannot possibly be taught over the internet. Most Hi Voltage AC Power Distribution Systems are 3 phase systems which don’t have a neutral. I connect Megawatt Generators to Ontario’s Power Grid, manually by using a synchroscope or automatically by computer control, but either way, they can’t be connected together out of phase. If you do, the big dog (The power grid) wins, but aren’t happy. So don’t think a portable generator will.

I have not seen so many internet experts in my life on this subject.  Google up the square D manual tranferr switch. Sold nationwide.
It is impossible to feed the utility lines with this switch installed.
Me thinks some folks need to come up to speed on this subject, lectricians and mega buck transferr switches are not in style in my neck of the woods.
As far as having to hook a generator to each buss in ghe service panel - I don't need to do that nor do i have the need for 240 volts when on emerbency power (fortunate i guess).
So for me, after I lock out the main circuit breaker that feeds the panel and flip all the 240 breakers on the panel off, I merely have to jump the two busses together to have 120 volts throughout the home.

And you could be over loading a neutral.

Reverse feeding a distribution line is doubly sticky because high voltage transformers can be one of two types: Subtractive or Additive Polarity. This is phase orientation. Generators must be paralleled by matching output potential. There must be zero differential voltage between generator frames. There must be zero voltage between neutrals. There must be zero potential between L1 connections. And finally the machines should be operating at 60 hz. Trying to synchronize out of phase muse be done by computer.

How do you "jump the two buses together", with tin foil ???

The statement that this subject is not suitable to teach in a web forum is all one needs to understand and act upon in my experience.
I think many with military experience know/have seen or HEARD what can happen when changing from one power source to another is not down correctly.
Two cheap generators have not business connected to a home wiring system as mentioned in the OP.

There are many ways to jump two buses together.. Most use wire or a switch. I notice that poster mentioned LOCKING OUT the main breakers.. I assume he has one of the dual breake lock out transfer systems (you turn OFF the main, slide a lock out bar and turn on the AUX. to power the house.
Though I do not like this system as well as I do the external transfer switch (Like the Square D) as opposed to the in-box dual breaker systems. both work well. PROVIDED YOU DO NOT REMOVE THE COVER FROM THE BOX.
I used a somewhat more complex transfer switch, it switched selected circuits over. Not the whole house, but otherwise it worked like the Square D. Absolutly NO way to back feed.
Nothin adds excitment like something that is none of your business

I considered doing it, and even had an outlet wired with heavy gauge wire back to the panel to use with a suicide cord. I talked with an electrician friend who said that a power company lineman would find me if I ever used it, and would do more than just kick my butt.
I relented and installed an interlock on my electrical panel, with a new outlet to properly receive my generator power cord. The electrician installed it and found a 10KW electric-start generator all for less than $1500. In two years, the power has not gone off yet, and my butt has been left un-kicked for that reason.
