120V Electrical Wire Tracer - I inherited a major panel field from a homeowner that wasn't always fond of meeting the desired nec codes. As such, there are some oddities inside the panel. One such oddity is the fact that he installed more than one tandem circuit breakers to be used in a hundred and twenty/240 circuits.

I've study that tandem breakers may be mounted to either feed power from one leg of the bus bar or from two special legs. If it's the latter for your case, then you definately'd be getting 240v in spite of everything. Test the terminals of the breakers in question (or test at the retailers wherein your appliances are plugged in) with a voltmeter, if you have not already, and confirm what's certainly being fed in your home equipment.

I want to strain that this clearly is working. Both the dryer and water heater were stressed out this manner properly earlier than i moved in and it is best now, years later, that i noticed what turned into taking place. It is worked exceptional all along.

It sounds like you may be mistaken as to how this is stressed, or that perhaps i am simply now not knowledge your explanation. As others have stated, it is now not possible to get 240 volts from a single pole in a a hundred and twenty/240v break up phase device. Each tandem breaker presents 2 a hundred and twenty v circuits, that is proper. However, in case you degree among the terminals on a single tandem breaker, you will get zero volts. This is because the terminals are both powered from the identical leg, and so are at the same voltage potential. In case you degree from a terminal at the top tandem breaker to a terminal on the bottom one, then you'll degree 240 volts. That is because each breaker is connected to a exceptional leg, which might be each one 1/2 of a 240 volt circuit.

Within the case of the dryer circuit, there may be one 10/3 nm twine, with the recent black attached to one of the facets of the tandem breaker and the hot crimson attached to the alternative facet. The neutral is attached to the impartial bar. Inside the water heater case, there is a ten/2, with both the white and black connected to their respective sides of the tandem breaker.
