Principles of electricity
Protons & Neutrons are contained inside this part of the atom
This voltage is supplied on a 2 pole breaker
240 Volts
this kind of PPE is used to protect the eyes
safety glasses
This is a symbol of a....
switch
this hand tools is used to twist wires together
linesman
1-3 electrons are in the valence layer of this kind of material
conductor
This law is the relationship between voltage, current and resistance
Ohms law
To ensure a de-energized circuit does not become live this safety device is installed
lock out
This type of diagram is a flow chart that indicates the relationship between circuit components
block diagram
this direction must be used when twisting wires together
clockwise
like pressure in a pipe this is the pushing force on electrons
voltage
This book is used to reference all of the rules of electricity
code book
When electrocuted this is what harms/ kills you.
amperage
these three things are required in every circuit for electrons to complete their journey
source, load & conductor
the neutral wire must be attached to this colour of screw on a receptacle
silver
to measure resistance in a circuit this symbol is used
omega
These two reasons cause a breaker to trip
Ground fault &
Overloading (over current)
a ladder is to be installed at these angles
3,4 5 triangle
This type of diagram is similar to a pictorial drawing without the 2 dimensional components pictures
wiring diagram
This is where it is safe to hold a receptacle
top/ bottom
In this equation
E= 12
I= 3
R will equal?
R= 4
A #14/2 AWG wire is sized for this amperage size of breaker
15 amps
this is a danger of hooking up the wrong polarity
- what is not supposed to be "hot" is, can cause people to get hurt
this type of drawing shows:
•electrical relationship between components of a circuit
•Shows HOW circuits works instead of what it looks like.
schematic
this shows on the plug tester when an outlet/ extension is wired properly
two right lights
