Why Do Electrical Prongs Have Holes in Them? | HowStuffWorks 4 What happens if outlet is wired backwards? A place where magic is studied and practiced? So although flipping the plug around and inserting it backwards will probably be no problem with regard to the electrical operation of the appliance, it may create a safety hazard by exposing the hot half of the outlet, the half not connected to Earth, such that someone might touch it and be shocked. The hot wire is the conduit for electricity that powers the appliance, and the neutral wire is the return path for electricity back to the service panel.

Make sure that the earth clamp is made from a strong material, such as metal. On a conventional 120-volt two pronged electrical outlet that accepts grounded plugs (two prongs plus the rounded center ground connector prong), your circuit will have three wires: The white neutral wire this wire is connected to the silver screw on the electrical receptacle, often labeled neutral or white. The negative wire carries electricity away from the power source, and the positive wire carries electricity towards the power source. This may not sound like a terrible thing, but it is. If you try to insert the plug the wrong way, it wont enter. That is very different from "positive and negative" in a battery, which is direct current (DC): the two poles of the battery have different potential, with a (more or less) constant potental difference (voltage) of, for example, 1.2V; one pole is the "positive" one, the other the "negative". The L or Line side is always hot and carries the full voltage of the appliance or device. 6,144 MB if, Theyre encouraging people to eat mor chikin instead of eating them by going to burger joints.
