An inaccurate description, technically

A grounded outlet has a wire that runs to a metal plate or frame that is buried in the ground. This is a safety device to help prevent someone from getting an electric shock because electricity always wants to take the shortest route to the ground.

If you attempt to mess with a non grounded circuit you may get shocked because the electricity will go through you to get to the ground. On a grounded outlet, the current will go straight through the grounded wire, because metal is a better conductor.

Normal American-style outlets have 3 holes, two straight conducting sockets and a bottom grounding socket.

However, some extension cords may not have 3 holes, so they are not grounded.

The male end of a cord - the end with prongs, not holes - also matters: if it does not have prongs that go into all three holes, it is not grounded.

Some better descriptions

The ground wire is connected to the outside metal casing of the appliance. It guarantees that if somehow the live or "hot" wire in the appliance shorted to the case, you won't get a shock - because the short circuit current will go to ground and not through you - and, in doing that, it will trip the breaker to cut off the supply of current.


The purpose of the ground wire on an appliance or in a house branch circuit is to provide a low impedance low resistance return path for the fault current to return to the distribution panel. This high return fault current will cause the circuit's breaker to trip and disconnect the fault.


The ground wire usually doesn't have anything to do with the normal electrical functioning of an electrical appliance but - because the ground wire is connected to the chassis or casing of the appliance - if an electrically 'hot' wire breaks or its insulation chafes so that it touches the chassis or casing, it will be shorted to ground via the ground wire, causing a very high current to flow in the 'hot' wire.

That high current will cause the circuit breaker to trip or a fuse to blow, thus cutting off the current and preventing the chassis or casing from electrocuting the user. Shutting off the current should also prevent the wires in the circuit from heating up so much that they catch on fire. Such a fault can easily be the cause of a serious house fire.

It's always dangerous to have a 3 prong outlet that isn't grounded unless it's a GFCI outlet or electrically down stream from a GFCI outlet. Down stream means the outlet is further away from the circuit breaker -- not physically further away, but further from the breaker electrically

Because Brian McFadden was naughty, and Shane Filan told his Dad. Then Brian's dad said "That's it, you're grounded, grounded, grounded, grounded, grounded, grounded, grounded, grounded, grounded, grounded, grounded, grounded, grounded, grounded, grounded, grounded, grounded, grounded. Go to your room. NOW!" Brian then cried to his room, only to jump out of his window, then onto a tree. Then there was Shane. Shane had a gun, then shot Brian. Brian McFadden died.

First you would have to know if the porch light is properly grounded or protected with a GFCI, or both. You cannot have outdoor outlets that are not GFCI protected.

Make sure that all electrical outlets in the bathroom are grounded to prevent electrical shock. When in doubt, consult an electrician and have a GFCI (ground fault circuit interrupter) outlet installed.

No they do not have electrical outlets

The word grounded is a verb. It is the past tense of ground. Grounded is also an adjective. For example, a child is "grounded" when they misbehave and aren't allowed to leave their room or the house to play with friends.

i recommend it to be grounded, but mine was not grounded for years and still worked. if you don't ground it it may cause damage to the coil tho

There is only 2 forms of Ground fault protection. A breaker or a recptacle (stadard plugs and outlets). Both are obvious to the naked eye. A recptacle will have a test and reset button that will turn it on and off. This is a sensor that constantly monitors the diffence of potential between the HOT wire and the grounded conductor . If this gets to and unacceptable limit It will trip. The breaker will have a test and reset button next to the switch. The complicated part is that 1 GFI outlet can protect multiple outlets. When it is hooked up it has an option to Downstream other outlets. Theese outlets are then monitored by the same sensor in parralel with the first. The best way is to push the test button and check for outlets that shut of with the GFI. Code requires a GFI protected outlets to have a sticker on it stating that fact. A breaker wll protect the entire circiut from ground faults provided it is hooked up correctly.

An ELCB (Earth Leakage Circuit Breaker) distribution box is a type of electrical box that is used for electrical GFCI (Ground Fault Circuit Interrupter) outlets. This is the type of outlet that requires a three-prong plug in, one wire of which is grounded. GFCI outlets are set up so that if there is a circuit overload, the outlet is shut off until it is reset, manually.
