I mentioned that in a previous post, if you look at a panel each leg "leap frogs" as it goes down the panel. This is why a 22ov breaker is side by side, it grabs "both" hot legs, so any issue from the transformer, and ANY of the connections through the OUTPUT connections of the main breaker will cause the malfunction on every circuit, which is at every other breaker.
Generally breakers directly across from each other are also on the same leg.
For basic understanding a 220V supply has TWO 110 volt legs, that are out of phase by 180 degrees. So voltage between the 2 hot legs is 220v, but between EITHER leg and the neutral is 110 v.
So 220 comes in through the main breaker and down the 2 buss', that skip every other space in the panel. A 110v circuit grabs one side and the neutral, a 220v circuit grabs both hot legs.
