17 New Can 10 Gauge Wire Handle 40 Amps Photos - Changed to in shape to new furnished data. Rapid petey's answer incorporates the circuit breaker you want to put in to correct the scenario. As you could see from the breaker inter-ties, they basically take of those breakers and manually end off what the installer turned into trying to do in a secure way.
Also related is the fact that all and sundry now not taking note of the panel setup may power off the circuit to work on it and no longer comprehend they switched off adjoining pairs in preference to change pairs of each 240v circuit, leaving a hot leg within the circuit they assume is powered down. You need things to be fail-safe. This is not fail-secure, however is a booby trap awaiting the inattentive or moved quickly. Nec frowns heavily on things like this.
I ran throughout a panel these days that has a water heater and a dryer installed the usage of tandem breakers. They may be not split either. This panel is configurable to half a slot, meaning a everyday 110vac breaker could be clipped into 2 prongs of a live bus, and there's a small plastic wall isolating the b aspect from the a side retaining you from shorting the 2 110vac circuits together. But, the tandem breakers have a slot reduce out allowing you to plug into each aspects. Each aspect of the tandem breaker gets its own feed from its very own prong at the buses making 220vac.
It seems like you will be fallacious as to how that is stressed out, or that possibly i am just no longer information your clarification. As others have mentioned, it's now not feasible to get 240 volts from a single pole in a a hundred and twenty/240v split phase system. Each tandem breaker offers 2 one hundred twenty v circuits, this is real. However, if you measure among the terminals on a single tandem breaker, you'll get zero volts. That is due to the fact the terminals are both powered from the identical leg, and so are at the same voltage potential. If you degree from a terminal on the top tandem breaker to a terminal on the bottom one, then you'll measure 240 volts. This is due to the fact every breaker is hooked up to a unique leg, which are each one 1/2 of a 240 volt circuit.
