A grounding conductor is a means for providing safety for users of electrical devices that may have experienced an internal failure that causes an electrical short to metallic surfaces. In theory, such a short to a GROUNDED surface would quickly result in overcurrent or ground-fault interruption of the circuit, resulting in an dead but safe circuit. NEVER "reset" a GFCI while holding the attached device or without discovering what caused it to trip.
Were it not for a grounding conductor, the user could become the "grounding conductor" by accident, causing electrocution.
Grounding conductors maybe bare (copper) wires or have green insulation, or green with a yellow stripe (also used for bonding) or other green markings (green screws, green clips, green wire nuts, etc).
Grounded appliance plugs were not required in the NEC until the 1960s.

Are child proof receptacles required in the new national electrical code?
Yes, they are required by the national electric code.
Is electric current and current the same thing?
Not really. You can compare them with the analogy of water flowing through a pipe. For water to flow, there must be a pressure difference across the ends of the pipe. An electric current is a movement of electric charges along a conductor. For those charges to move, there must be a voltage (more accurately, a 'potential difference') across the ends of the conductor. So a potential difference is required to cause current to flow.
What 3 things are required to induce a voltage in a conductor?
three things required for electromagnet are hands eyes ears have fun! lol
Can I get electrocuted touching an electric pole if I'm not grounded?
First off you should not be touching any high voltage source whether you are grounded or not. A pole isn't typically dangerous, it is the wires on the pole. A path to ground is required for a current to flow. Technicians working on high voltage power line often touch the lines and ensure they are not grounded when doing so, by using special procedures. That is why birds can sit on bare power lines without getting shocked.
What are 3 things required to induce voltage?
A magnetic field, a conductor and movement.

Yes, they are required by the national electric code.
What force is required to cause electrons to move through a conductor?
Electric field, a directional vector
Is a ground fault protection for equipment required even if the neutral will not be used?
Yes, ground fault protection for equipment is requiredeven if the neutral will not be used.However, the question implies that it might not be required if there is a neutral. That is not true. With two exceptions, ground fault protection is always required in the US, and it is probably required in other countries as well.The exceptions are the use of an electric cooking range, and an electric clothes dryer. In those cases, the US NEC allows the neutral conductor to also be the ground fault conductor, except for the case where the range or dryer is in a mobile home. In the case of the mobile home, the ground fault conductor and the neutral conductor must be maintained separate and distinct all the way back to the distribution panel.In every other case, including where local code overrides the US NEC's exceptions, it must be understood that ground fault protection (protective earth ground) is not the same as neutral, even though the neutral conductor is grounded.
Can a liquid retain electrical charge?
Yes. In fact a moving liquid can generate an electric charge. When oil truck fill-up they are required to be grounded to avoid an igniting spark.
What is the Color of neutral wire in 120 volt circuit?
For wiring in the USA the Neutral conductor is required to be white or gray by the National Electrical Code.
How do you decide cable size for required load?
i=v/R and R=rho.L/A . by analysing these fourmulas we find the size . here i is electric current in the conductor to flow or load current to flow . v is the voltage across the conductor , R is the resistance of the conductor . L is the length of the conductor ,rho is a constant of a material called specific resistance here the the material is the material of the conductor , A is the area of cross section of the conductor .
Does one tip a conductor on a train?
A person is not required to tip a conductor on a train. Amtrak doesn't discourage tips, but advises customers that tips are not required for either the attendants or the conductor of the train.
Is equipment ground required in EMT conduit?
Yes it should be grounded

When does the electric current flow?
An electric current will flow if there is a voltage, and a conducting path (usually a closed circuit is required).An electric current will flow if there is a voltage, and a conducting path (usually a closed circuit is required).An electric current will flow if there is a voltage, and a conducting path (usually a closed circuit is required).An electric current will flow if there is a voltage, and a conducting path (usually a closed circuit is required).
