15 Perfect 30, Breaker On 12 Gauge Wire Collections - What is wrong -- the principal protection problem right here is that with a circuit fault, most effective one of the breakers within the set can also journey, leaving the 240v circuit partially energized. As an example if the dryer heating coil burns through and one end touches floor, that facet will trip, leaving the other leg hot. You truly need a circuit fault to completely power down each legs. In the case of the dryer circuit, there is one 10/3 nm cord, with the recent black attached to one of the sides of the tandem breaker and the new crimson connected to the other facet. The neutral is connected to the neutral bar. Inside the water heater case, there is a ten/2, with both the white and black attached to their respective sides of the tandem breaker.

Murray bus backplane with interleaved hands so adjacent full size breakers are on contrary legs. No longer proper for the mh-t mp3030 breaker pair, every breaker within the set is 1/2-width and the mixture is fed off handiest one leg blade. Especially, there are two murray mh-t 30-amp breakers. These are tandem breakers and now not "slimline" or "skinny" breakers -- the 2 breaker switches on every are not connected in any manner. One of these breakers is used for the clothes dryer and the opposite for an electric water heater.

The setup is operating because every breaker pair feeds off the proper panel bus leg (one attaches to l1, the alternative to l2). Out of your delivered facts, each 240v circuit is break up across the two breakers to do this. I inherited a prime panel field from a home owner that wasn't usually fond of meeting the specified nec codes. As such, there are some oddities inside the panel. One such oddity is the fact that he established more than one tandem circuit breakers for use in 120/240 circuits. Modified to suit to new furnished facts. Rapid petey's answer contains the circuit breaker you need to install to correct the scenario. As you may see from the breaker inter-ties, they basically take of those breakers and manually finish off what the installer became trying to do in a safe way.
