Atomic Theory
The 3 principal parts of an Atom and their charges
Proton+, Neutron 0, Electron -
Opposite Charges do this
Attract
The 3 Overcurrent Conditions
Overload, Ground Fault, Short Circuit
All Duplex Receptacle power is ____Volts
120V
The Force that creates pressure in electrical theory
Voltage (EMF)
This makes up the Nucleus
Proton Electron
A material that can be easily magnetized
Ferromagnetic
This is the most violent of the over current conditions
Short Circuit
Typical Commercial Lighting is ____Volts
277V
Conventional Flow
Positive to Negative
The Smallest Part if an Atom
Electron -
A Magnetic Field is Produced when a conductor is energized. When another conductor cuts that magnetic field, a current is induced in that conductor. Transformers take advantage of this principle.
Induction
A ground fault is described as
An ungrounded (Hot) conductor or connection that comes in contact with a grounded surface or material
How to get 480V
2/3 phases 277V
Two or more conductors carrying the same flow of current in the same direction
Parallel
Electron flow
Negative to positive
A magnet that requires current
Electromagnet
_____ protection is required for all residential 10,15-, and 20-AMP branch circuits
AFCI
To Get 208V or 240V is determined by
The Transformer (System)
When Voltage increases Current does this
Increase
The force that maintains the electron orbit
Centripetal Force
This motion is required to produce current with magnetism
Relative
When sharing Neutral's all ungrounded conductors Must Be _______.
Of Different Phases
Insulation is rated for maximum voltage present (600V)
Minimum size for Parallel feeds
1/0 AWG and Larger
