If that could EVER happen, then the electrician that installed it should lose his or her job.
Stuff like that can not happen if installed properly.
And Your "Short" would have to be in the breaker box, or the current for each breaker will not be divided by half, It will depend on the resistance of the wire on the Other "Short".
Is everyone confused yet ?
We all need to stay on the same page.

Theory only works perfect in a vacuum.
Residential wiring is so simple I would generally agree with you, however, even then, I've seen mice chew through insulation and people put nails through wires.
Yup.. that is correct. That said, the difference in the lengths of the wires would have to be significant to create enough of a resistance to have any real world effect.And Your "Short" would have to be in the breaker box, or the current for each breaker will not be divided by half, It will depend on the resistance of the wire on the Other "Short".
Wouldn’t your two wires also add up?
Hasn't this died down yet?
I too have a piece of paper that says how wonderful I am -- BSEE from University of Washington. The funny thing is, I think I forgot more while at the U than I learned. I wired my first light switch when I was 6 years old...
As JW was busy quoting the NEC, I was Googling for dictionary definitions and reading Wikipedia, etc. After filtering out all the fluff, the one "definition" that stood out said something like "a short bypasses part of a circuit".
I don't agree that a short is always unintentional -- if you intentionally set a crescent wrench on a car battery that would be a short in my book (don't do that BTW).
I roomed in a house once that you needed to turn off three breakers to kill anything and everything. Wonder if it's still there.
I have been doing electrical work since 1966. I have done about everything one can think of from wiring single wide mobile home to water plants at 4160 volts and the one thing I have never seen is what you are describing.
Yes I know that industrial maintenance men get to see everything but in most cases it is because they install the mess.
Having done consulting in many plants around my area I too have seen some pretty sloppy work done in the industrial plants. It has been my experience that the reason behind this type of work is the lack of education and supervision. In other words if the boss don't know how can he guide.
One of the other posters in this thread commented he had a house that had this problem happen.. but his breakers were on different phases so they popped immediately. That said, I'm sure there are lots of things you have seen that I have not.. I am not an electrician who pulls wire for a living. I've certainly done my share of it, but its not my normal daily job.I have been doing electrical work since 1966.

My daily job is to cruise forums and nik pick at folks like you! LOL
At my ripe old age all I do is sit around trying to remember those things I have forgotten.
Now let’s see, is it the base times the height or is it the base squared plus the height squared then we have to make a root square…………… no, no, no it is if you have a tree that has square roots then it won’t get very high and you will have to hide the pot in a noose. Yea that’s it and also if you try to borrow money at the bank and they won’t let you sine you have someone to cosine for you. Well let’s not get off on a tangent here.
I still feel sorry for poor ole Oscar because Oscar had a heap of apples and that is all anyone needs to know to find the sine or the cosine.
Lots of fine folks think that ½ equals one half but to the wise they will say that ½ is one divided by 2 or that ½ is the reciprocal of 2
Such nonsense that I once remembered while the young of today can only think about getting horizontal.
