As others have cited, it is not feasible to get 240 volts from a single pole in a a hundred and twenty/240v break up phase system. Each tandem breaker offers 2 120 v circuits, that is real. But, in case you degree between the terminals on a single tandem breaker, you may get 0 volts. That is because the terminals are both powered from the same leg, and so are at the equal voltage potential. In case you degree from a terminal on the top tandem breaker to a terminal on the lowest one, then you will degree 240 volts. That is due to the fact every breaker is hooked up to a one of a kind leg, that are every one half of of a 240 volt circuit.
I ran across a panel nowadays that has a water heater and a dryer set up the usage of tandem breakers. They are now not split both. This panel is configurable to half of a slot, which means a regular 110vac breaker might be clipped into 2 prongs of a live bus, and there may be a small plastic wall setting apart the b facet from the a side preserving you from shorting the two 110vac circuits together. But, the tandem breakers have a slot reduce out permitting you to plug into both sides. Every side of the tandem breaker receives its own feed from its own prong at the buses making 220vac.
Notice how the internal handles are tied collectively, and that the outer handles also are tied to every other. This way if either experience (or are became off by using the user), the complete circuit is shut off.
The handiest trouble is connecting the two switch handles. Manifestly a nail or piece of twine will work but it looks shoddy. There truely is a actual product for this, known as a circuit breaker cope with tie. I just sold some myself on the local large orange home development save to replace a bit of cord caught through one in all mine.
