This article was listed on Wikipedia:Requests_for_page_expansion as being too technical, so I tried to make it a little more accessible. I replaced the following paragraph with a summary statement, but thought I would leave it here for reference.

Really?, If you want "technical", you should read some of the medical articles on Wikipedia, that talk in a language that only doctors and wannabe doctors understand. Having said that, this article uses only US references, as in, the rest of the world calls "ampacity", everyone else in the world calls current-carrying capacity.

Picky detail: Short circuits are not prevented by fuses and such. The short circuit occurs and the circuit then opens because the fuse blows. The fuse prevents damage from a short circuit.. — Preceding unsigned comment added by 66.227.89.85 (talk • contribs) 22:04, September 27, 2004
And your point is? All fuses and circuit-breakers conform to a simple I²t curve, the higher the current, the quicker the protection will operate. Trumpy (talk) 09:30, 25 September 2012 (UTC)
"charge is allowed to flow between a phase and the electrical earth or between two phases" - this doesn't seem very accurate to me - a short circuit can occur in lots of other combinations of conductors (phase to neutral, or any number of other possibilities in the case of more complex apparatus especially DC-powered systems). The "unintended path" definition sounds much better. Any objections to me rewording this? — Preceding unsigned comment added by Ali@gwc.org.uk (talk • contribs) 03:16, January 8, 2005
I think too much emphasis is placed on a short being unintentional. There are many instances (such as illustrated in the final two paragraphs) in which a short is desired. One technical definition might be, “A short is when two nodes of a circuit are directly connected.” In many cases this is a fault and unintentional. Also, the term “resistance” is used in the definition. I feel a more accurate term would be impedance. An ideal inductor has no resistance, but it is not considered a short. In a DC case however, this inductor would act as a short. I also argue that in a transformer (or power outlet as in the article) there is already very low resistance between the phases; but there is a large impedance. I offer that impedance be the prominent term used in the article.Mak17f 19:07, 10 December 2005 (UTC)
You guys don't have a clue about what you are discussing, let alone asking for advice on this sort of thing, I've been a registered electrician and HV technician for 25 years. No, neutral does not count as a phase, it is the earthed component in any electrical system. What a short circuit is defined as, is when two (or more)conductors touch together, that should not do so in normal use, creating a fault current, that operates the system protection, on all poles of that circuit, making it safe. If that is too hard for you folks to fathom, don't bother commenting.Trumpy (talk) 09:47, 25 September 2012 (UTC)
I think we should make this page more useful to students in an intro circuit analysis class. I think, in the class I'm taking at least, we use short circuit to mean a plain, zero-resistance wire. E.g.
These are the only times I heard the term 'short circuit' in this course (I have to admit that I didn't go to class very often, which is why I'm sitting here reading circuits articles the night before the final (the textbook sux)). My only other experience with the term is from the movie about the robot that (who, to be P.C.) got struck by lightning and started to feel emotions and things.
I think where I'm going with this is that this article somehow needs to be sectioned for different audiences and uses: everyday use, and varying levels of technicalness and academicness. But I'm nowhere near qualified enough to decide how to do this, or even to know that this is the right thing to do. — Preceding unsigned comment added by TriniTriggs (talk • contribs) 20:15, December 13, 2005
I havent heard this term. Are there any refs?--Light current 00:14, 8 January 2007 (UTC)
I think that this statement should be removed. Generally speaking, people can die from the resultant conditions of a short circuit (explosions, fires, etc), but this is not always the case.
Also, it is misleading readers into thinking that a person can cause a short circuit. In most cases if a person contacts two phases or a phase to earth/neutral, the resistance of their body is high enough to even prevent the tripping of over current divices such as fuses or circuit breakers.
It is also breaking a point ( it seams to be inserted in a paragraph about something else). I will remove in a week unless someone else see's fit to remove earlier Blaab 08:59, 25 October 2007 (UTC)
Clod amateur home electrician me made a loop of his home wires. When I closed the circuit breaker I knew something was wrong as all thru the house the wires were vibrating loudly in their conduits in the walls. One second was long enough for me to quickly open back up the circuit breaker.
So mention this rarely observed brief phenomenon that is certainly forgotten while extinguishing the probably ensuing total house fire. Jidanni (talk) 00:24, 28 February 2008 (UTC)
That is so retarded, I can't even reply once the tears have stopped running down my legs from laughter. Trumpy (talk) 10:06, 25 September 2012 (UTC)
I suggest a defintion for short circuit current (Isc). This is used in solar panels.--Linegen (talk) 14:23, 13 November 2008 (UTC)
In the opening summary, it says "A short circuit in an electrical circuit is one that allows a current to travel along a path along where essentially no (or a very low) electrical impedance is encountered." Should 'electrical impedence' be changed to 'resistance'? —Preceding unsigned comment added by 67.158.25.23 (talk) 21:49, 14 May 2010 (UTC)
No, Resistance is only valid with DC voltage. Impedance, capacitive reactance and inductive reactance are common with AC voltages and currents. Read your text-books before replying. Trumpy (talk) 09:56, 25 September 2012 (UTC)
This article focuses too much on unintended short circuits. The very first sentence describes it as a fault. In reality shorts are frequently used to bypass certain series elements intentionally, often referred to as shunts. The first paragraph and "definition" sections especially need a broader description. How's this for size? "A short circuit is a conductive path between two otherwise separate conductors, which links isolated networks or causes current to bypass its normal path. Often the short circuit is the result of an undesired event, and causes excessive current to lead to further unintended destructive consequences. In other situations the short circuit can be planned, where current is intended to travel through the short instead of the usual path for maintenance or for some other intentional purpose." — Preceding unsigned comment added by 74.62.48.2 (talk) 20:27, 21 January 2015 (UTC)
The article refers briefly to "open circuit" as the opposite of a short circuit. Someone might elaborate on that, perhaps in a separate article. Most commercial power circuitry today provides a fixed voltage, and a short circuit causes the system to attempt to supply unsafe amounts of current to maintain a constant voltage. If the system were instead designed to supply a constant current, then an open circuit would be a fault, inviting the supply to increase voltage to unsafe levels. Streetlight circuits in the 19th century were like that, perhaps 6 or 8 amps to all the lights in series. Children were cautioned never to attempt to touch a streetlamp.
