12 Gauge Wire 30, Breaker - Modified to suit to new supplied records. Speedy petey's solution incorporates the circuit breaker you want to install to accurate the scenario. As you could see from the breaker inter-ties, they basically take two of these breakers and manually finish off what the installer turned into attempting to do in a safe manner. It feels like you'll be fallacious as to how this is wired, or that perhaps i'm just not understanding your rationalization. As others have cited, it is not viable to get 240 volts from a unmarried pole in a one hundred twenty/240v break up phase system. Each tandem breaker provides 2 120 v circuits, that is real. However, in case 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 equal leg, and so are on the equal voltage capability. In case you degree from a terminal at the pinnacle tandem breaker to a terminal on the lowest one, then you'll measure 240 volts. That is due to the fact every breaker is hooked up to a special leg, which might be every one 1/2 of a 240 volt circuit.
Especially, there are two murray mh-t 30-amp breakers. Those are tandem breakers and no longer "slimline" or "thin" breakers -- the 2 breaker switches on each aren't related in any manner. Such a breakers is used for the garments dryer and the alternative for an electric water heater. The setup is working due to the fact each breaker pair feeds off the proper panel bus leg (one attaches to l1, the opposite to l2). From your added statistics, each 240v circuit is split throughout the 2 breakers to do that.
Observe how the internal handles are tied together, and that the outer handles are also tied to each other. This manner if both trip (or are turned off with the aid of the person), the entire circuit is close off. Within the case of the dryer circuit, there's one 10/3 nm cord, with the recent black attached to one of the sides of the tandem breaker and the hot crimson attached to the other facet. The neutral is attached to the neutral bar. In the water heater case, there is a 10/2, with both the white and black connected to their respective aspects of the tandem breaker.
