Professional 12 Gauge Wire 20, Circuit Solutions - It appears like you may be incorrect as to how this is stressed out, or that perhaps i'm simply not know-how your clarification. As others have mentioned, it is not viable to get 240 volts from a unmarried pole in a a hundred and twenty/240v cut up segment system. Every tandem breaker provides 2 120 v circuits, that is real. But, if you degree between the terminals on a unmarried tandem breaker, you will get 0 volts. That is because the terminals are each powered from the same leg, and so are at the equal voltage capacity. If you measure from a terminal at the pinnacle tandem breaker to a terminal on the lowest one, then you will degree 240 volts. That is because every breaker is connected to a one-of-a-kind leg, that are each one half of a 240 volt circuit.

Also associated is the reality that everyone not taking note of the panel setup may additionally electricity off the circuit to work on it and no longer recognize they switched off adjacent pairs in preference to trade pairs of every 240v circuit, leaving a hot leg inside the circuit they think is powered down. You need matters to be fail-secure. This is not fail-secure, but is a booby lure anticipating the inattentive or hurried. Nec frowns heavily on things like this.

I ran throughout a panel these days that has a water heater and a dryer mounted the usage of tandem breakers. They may be now not break up both. This panel is configurable to half a slot, which means a regular 110vac breaker could be clipped into 2 prongs of a live bus, and there's a small plastic wall keeping apart the b facet from the a aspect keeping you from shorting the 2 110vac circuits together. But, the tandem breakers have a slot reduce out allowing you to plug into both aspects. Every side of the tandem breaker gets its personal feed from its very own prong on the buses making 220vac.

I inherited a prime panel box from a homeowner that wasn't always fond of meeting the desired nec codes. As such, there are a few oddities in the panel. One such oddity is the truth that he established a couple of tandem circuit breakers for use in one hundred twenty/240 circuits.
