Demonstration Main Points Assignment: Electrical Outlets
(Introduction)
Power, not the power to move an audience, or to take a drag car
down the strip at 200mph. But 7,200 Volts running down your
streets. That power is Electricity. Electricity being able to provide
light in your home, air and heat in your bedrooms and power to
your outlets. In our day to day lives we take power for granted
until we have the absence of electrical power and today I’m here
to educate you on a helpful home repair. In this demonstration we
will be replacing a GFCI outlet. Where we will be going over
safety, component names and their duties, removal and
installation along with verifying safe replacement of your GFCI.
This may seem like a daunting or even scary task. But today I
believe you’ll leave with a bit more confidence and electrical
education. So, let’s hop in.
Preview Statement: In this demonstration of replacing a GFCI
outlet we will be going over safety, component names and their
duties, removal and installation along with verifying safe
replacement of GFCI.
Main Points:
I. Electrical Safety
Before diving in to any electrical repair is to understand the
Safety steps. The number one thing taught in Electrical is safety,
it only takes less than 60 volts to be lethal. So, safety is key to
electrical. That 7,200 volts I mentioned running down your
streets, is actually transformed to a safe 120/240 volts entering
your home and the first that you are to do is locate your Breaker
panel. Commonly found in your basement, garage, storage and
utility rooms. It’s identified by a grey rectangular metal panel and
when opened shows each breaker and what it controls in your
home.
A breaker box is there to save your home and electrical
devices from overheating and causing potential fires and total
device failure. When it reaches a certain amperage above its
designed capability the breaker “trips” and closes to stop the
power from continuing from that point. But in situations where
you’re working on home electrical components, you always turn
off the breaker to stop the power from entering that area of the
home.
Once you’ve identified the breaker panel and which breaker
you need to turn off, you will need to verify that the power has
actually been turned off. In doing that, you will need a volt meter.
A volt meter will read the current voltage, amperage and other

Once you’ve identified the breaker panel and which breaker you need to turn off, you will need to verify that the power has actually been turned off. In doing that, you will need a volt meter. A volt meter will read the current voltage, amperage and other

Kenneth Crump settings depending on the type of volt meter. You will place the volt meter to the AC setting (alternating current). Then place the positive (red) and negative (black) leads in to the top two sockets of the GFCI to test for incoming voltage. You’re looking for 0 to 3 volts. If 0 to 3 volts isn’t present, go back to your panel and verify which components were turned off and check again until 0 to 3 volts are present. You may ask why would there be any voltage present. That is because there is what is called a “phantom voltage” where wires are slightly energized by neighboring wires that have power applied to them. No need to worry it’s common. Do not procced until this is done, replacing a GFCI “live” (Voltage present) is very dangerous and could be lethal. Now that the breaker has been identified, the breaker marked for your location has been turned off and you have 0 to 3 volts present at your GFCI. Now it’s time to start identifying the components and preparing for the task at hand. II. Component Names and Duties The outlet is a simple component that allows the US standard plug to be inserted and provides power to your device. The outlet is made up of two 120v receptacles and are powered by a single 120v incoming wire and that wire is placed on the HOT terminal side. The other two wires ran to the outlet are your neutral and ground. Neutral (which completes the circuit) goes to the other top terminal on the opposite side of the HOT terminal and ground goes to the green plated screw, located on the back or side of the outlet. Now that we know what we are working on, how it works and what its duties are let’s jump in to the fun part, removing and replacing the outlet. III. Removal and Instillation Very first thing you’ll have to do is remove the top and bottom screws holding the faceplate over the outlet. Once removed you’ll be removing the top and bottom screws out the outlet itself, which will free the outlet from the wall. You now have the ability to pull the outlet out from the receptacle box exposing the three wires we spoke of previously in the back of the outlet. Before you remove the wires write down the color of the wire and where it went on a piece of paper. There is no particular order you need to remove the wires from the outlet, I commonly start left to right, to bottom. Once written down remove each wire by loosening the screw enough to free the wire. Move the wire off of the terminals and you’re now able to remove the GFCI completely. Once you have removed the outlet completely grab your new GFCI and work in reverse. Placing each wire, you removed back on to the outlet terminals as written and screw down the terminals tightly.
