I suspect that it is because a coiled wire becomes an electro-magnet which disipates and uses energy, and is therefore not recognized as a short.

Why is it that if you take a piece of Copper wire and plug it into a power supply it creates a short circuit but if the same wire is coiled then it acts as an inductor and doesnt make a short circuit?
=== === This answer assumes the wire is properly insulated along its length so that it does not have any shorted turns if it is wrapped around a core made of a good insulator such as wood or plastic. Whether or not it is wound into a coil the resistance of a piece of copper wire depends on how long and thin it is. The thinner and longer the wire, the higher the resistance it will have and the less current it will draw from the power source.A very short piece of thick wire will have such a low resistance it will take so much current that it will behave just like a short circuit. (Whether it is insulated or coiled even a little bit will make no difference.)If a sufficiently long length of insulated wire is made into a coil it will act as an inductor. If it is wound around a cardboard or wooden core containing a piece of iron, the iron would make the coil have a much higher inductance than for just air.
What is principle of Current transformer?
why does have to short-circuit secondary wire of current transformer ?
What is shot circuit?
When there is a very current flow with virtual no voltage caused a hard wire short
Will voltage or current be higher in a circuit during short circuit?
Since a short circuit is, essentially, a zero impedance connection between nodes, the current in a short circuit is limited only by the ability of the source. In the case of an ideal voltage source connected to an ideal short circuit, you would have infinite amperes.
Can one use 1 circuit of a 3 wire plus ground 2 circuit cable as a GFI circuit with the other as a lighting circuit?
A GFCI can not be used on a three wire branch circuit. It has to be on a single two wire circuit.
Why is the three-layer insulated coil less prone to short-circuit failure?
Coiled around copper core wire, no flow blocking element. Why is this insulated wire coil not prone to short-circuit failure?
When you make a homemade electromagnet with wire and a nail and a battery does stripping the wire that is coiled around the nail make the electromagnet stronger?
No, this will stop the magnet from functioning and is the same as using a short thick wire instead of a long coiled wire.
How does short circuit occur?
short circuit occurs when two wire which consist of one live and neutral wire are in contact with the main and the other end of the wire are touched each other short circuit occurs
Why wiring short circuit?
A "hot" positive wire has made contact with ground = short circuit.
Why would a computer wire melt?
Short in the circuit or the circuit was overloaded.
What happens if a wire breaks?
The circuit stops working because of the short circuit

How do you correct a short circuit?
A short circuit is repaired by first finding out where the short circuit occurred. On major faults usually the wires are removed and new wires are installed. On minor faults, the wire that shorted is separated from the offending wire or separated from the grounding medium. To put the conductor back into service the wire's insulation has to be brought back to the level of what the wire was when it was new. Once that is done the circuit can be re-energized.
Does the green ground wire have to be grounded to the stove?
Yes, the ground wire should all ways be connected. This is the short circuit current return path that trips the breaker in case of a short circuit in the unit.
What two wires touching causes a short circuit?
the red wire and the blue wire A touching of two wires coming from any potential power source will cause a short circuit Short circuit relates to the quickest path back to the source with out any resistance to the current flow.
How a fuse can provide time delayed protection for normal overload and high speed protection for short circuit?
There are two sections of the fuse; a straight wire section that provides quick acting response to short circuit conditions, and a coiled spring section with a soldered lump with thermal mass that provides time delay for normal overload. When inspecting a blown fuse, you can tell if it was a short or an overload by looking at where the blowout occurred.
Why a short circuit happen?
Presumably, the current follows a path (a circuit) to do whatever it was "made" to do. If water, for instance, enters the circuit, a shorter path may develop, and the current will (partially) take the short circuit. Or a wire could become lose and short circuit the intended path.
