What is a Ground Fault Interrupter?

New Bern Electricians

If one of your outlets does not work, check the ground fault breaker that is located either in the electrical panel or on one of the outlets.

A ground-fault circuit interrupter,(GFCI), is there to protect people from electrical shock, so it is completely different from a fuse. The idea behind a fuse is to protect a house from an electrical fire. If the hot wire were to accidentally touch the neutral wire for some reason (say, because a mouse chews through the insulation, or someone drives a­ nail through the wire while hanging a picture, or the vacuum cleaner sucks up an outlet cord and cuts it), an incredible amount of current will flow through the circuit and start heating it up like one of the coils in a toaster. The fuse heats up faster than the wire and burns out before the wire can start a fire.

A GFCI is much more subtle. When you look at a normal 120-volt outlet in the United States, there are two vertical slots and then a round hole centered below them. The left slot is slightly larger than the right. The left slot is called "neutral," the right slot is called "hot" and the hole below them is called "ground." If an appliance is working properly, all electricity that the appliance uses will flow from hot to neutral. A GFCI monitors the amount of current flowing from hot to neutral. If there is any imbalance, it trips the circuit. It is able to sense a mismatch as small as 4 or 5 milliamps, and it can react as quickly as one-thirtieth of a second.

So let's say you are outside with your power drill and it is raining. You are standing on the ground, and since the drill is wet there is a path from the hot wire inside the drill through you to ground (see How Power Distribution Grids Work for details on grounding). If electricity flows from hot to ground through you, it could be fatal. The GFCI can sense the current flowing through you because not all of the current is flowing from hot to neutral as it expects -- some of it is flowing through you to ground. As soon as the GFCI senses that, it trips the circuit and cuts off the electricity.

How does an AFCI (Arc Fault Circuit Interrupter) circuit breaker work? 

 AFCI breakers are the latest advance in life safety and fire protection. Basically - The arc fault circuit breaker continuously monitors the shape of the sine wave of the electricity passing through the AFCI breaker. Anytime the sine wave is uneven or jagged, there may be a sparking condition somewhere down the line. In this case the AFCI breaker will click off. Most of them also will light one or two tiny LEDs on the front of the breaker. By reading the instructions you can determine if it was a hot-to-ground fault or a hot-to-neutral fault.

An AFCI breaker does not do the same thing as a GFI or Ground Fault Circuit Interrupter.

The AFCI uses a very simple computer chip that constantly checks for a sparking condition between the hot wires and the neutral wire. It also checks for a high resistance or over heating condition in either the out going hot wire or the returning neutral wire.

Generally it checks for any sputtering, sparking or overheating condition that might indicate a loose or overheating connection.
