10 Gauge Wire On 15, Breaker - Murray bus backplane with interleaved arms so adjacent complete length breakers are on opposite legs. Now not authentic for the mh-t mp3030 breaker pair, every breaker within the set is 1/2-width and the aggregate is fed off handiest one leg blade. The setup is running because every breaker pair feeds off the right panel bus leg (one attaches to l1, the opposite to l2). Out of your delivered data, each 240v circuit is break up across the 2 breakers to try this.
I inherited a chief panel box from a property owner that wasn't usually fond of assembly the required nec codes. As such, there are a few oddities in the panel. One such oddity is the reality that he established a couple of tandem circuit breakers to be used in 120/240 circuits. It seems like you'll be mistaken as to how this is wired, or that perhaps i'm simply no longer expertise your explanation. As others have stated, it's not possible to get 240 volts from a single pole in a one hundred twenty/240v break up section gadget. Every tandem breaker presents 2 120 v circuits, this is actual. However, if you measure between the terminals on a single tandem breaker, you will get 0 volts. This is due to the fact the terminals are both powered from the same leg, and so are on the same voltage ability. If you measure from a terminal on the top tandem breaker to a terminal on the lowest one, then you'll degree 240 volts. This is due to the fact every breaker is hooked up to a different leg, that are every one half of of a 240 volt circuit.
In particular, there are two murray mh-t 30-amp breakers. These are tandem breakers and no longer "slimline" or "thin" breakers -- the two breaker switches on every aren't linked in any way. This sort of breakers is used for the garments dryer and the other for an electric powered water heater. Additionally related is the fact that everyone not being attentive to the panel setup can also electricity off the circuit to work on it and not recognise they switched off adjoining pairs instead of trade pairs of every 240v circuit, leaving a hot leg within the circuit they suppose is powered down. You want things to be fail-safe. This is not fail-safe, but is a booby entice watching for the inattentive or moved quickly. Nec frowns closely on things like this.
