Tools
There
are plenty of tools for stripping wires. There is the wire stripper, it
comes in many different forms and many different sizes. The many
different wire strippers have colored handles, yellow , blue , and the
red. The yellow handle is for more smaller jobs, such as stripping the
smaller, thinner wires like the black, white, and green. The blue and
red wire strippers are for bigger jobs like cutting cables and is for a
more variety in wire cutting because of its variety of holes for
different sizes of wires. Other tools we use is a box cutter and a
screw driver. The box cutter is for pealing away at the shell of a
cable. The screwdriver is for connecting in the wires in to the plug
and screwing on the back to the front of the plug.
Stripping the Wires
When
you strip a wire, the first thing you do is to strip the outer shell of
the cable using a box cutter. By doing this, you are exposing three
wires. The wires you are exposing is the hot (black) wire, the neutral
(white) wire, and the ground (green) wire. Take the yellow handle wire
strippers (described above) and strip each wire, exposing enough
metallic wire to connect to the plug.
Connecting the wires to the Plug
In
the plug, there are three prongs with three connections. First connect
the green wire (it doesn't matter what order you do it in) to the third
prong by putting the wire in to the slot and screwing down. Now do the
same for the next to wires. However, there is still a place for each
wire. The black wire goes in to the gold colored connection and the
white wire goes in to the silver colored connection. Now screw down the
plug to the back of the plug with the three screws. Now, your plug
should work, after you plug it into the socket.
How the wires come from the Electric Co. to our circuit breaker.
When
the wires start off from the Electric Co. there are two wires, the
black and the white wires. The black wires goes to a transformer
outside the school, underground. The Transformer transforms the hot
wire's (black) high voltage to a lower voltage, while the neutral wire
bypasses the transformer and goes into the school. When the wires go
into the school, the black wire goes into the distributor. It
distributes the hot wire into three wires of 120 volts. The three wires
are blue, red, and black. The three wires goes into the Transformer
box. The circuit breaker, which is in the transformer box, limits the
amount of power that goes into the outlet. At the bottom of the
transformer box is a neutral bar where the neutral wire enters and then
goes straight to the outlet. The ground wire then comes up from the
ground and enters the transformer box and goes to the outlet. That is
how the power comes from the power company to the transformer.
Calculating Watts, Voltage, and Amps
Calculating
the voltage, amps, and watts is relatively easy is you know the
equation. The equation is Watts /Volts = Amps or W/V=A. There is an
easy way top remember this equation. The way is West Virginia, WVA is
the abbreviation for West Virginia.
ex. 100w / 1,000v = .1 A
100w / 100v = 1A
100w / 10v = 10A
