Why is grounding necessary in a circuit?

The bare (or green) grounding wire is for user safety. If there is a fault inside an appliance, a wire can become disconnected and touch other parts. If it is the "hot" side of the circuit, the parts can become energized (whether or not the switch is on). This is a dangerous hazard because a person can touch the appliance, while being grounded by touching something else, and "complete" the circuit; namely electrocution. With a safety grounding wire, there is a better chance that any parts a person could touch would be connected to the grounding wire, and thus the same hot fault would cause a short circuit to trip the breaker.

Is it necessary to ground at all metal junction boxes when using metal conduit or cable?

In a completely metallic conduit system it is not necessary to ground each junction box as long as the metallic system has the grounding capacity rating larger than that of the over current device protecting the circuit. The code book states what size conduits are rated at, for grounding amperages.

What is difference between system grounding and equipment grounding?

System grounding is done by connecting a conductor of a circuit to the earth to keep the voltage stabilized. Equipment grounding is when all metal frames of the equipment and conductors are grounded by a permanent connection. This grounding is done in case of an insulation failure.

What does grounding a connector mean?

"Grounding a connector" means you join a connector in a circuit to another point in the circuit that is definitely at ground potential. This is done mainly when testing a circuit, to be sure that a particular point in that circuit really is at ground potential if you are not certain that it is already. Alternatively, you could be doing a test to temporarily ground a connector that is not normally at ground potential, to see what effect doing the test has on the behavior of the circuit.

The difference between a neutral and a grounded circuit conductor?

The neutral is THE groundED conductor in a circuit, whereas the earth ground is called the groundING conductor.

Why it is necessary ground yourself before touching electronic equipment?

The circuits in electronics equipment are very sensitive and can be damaged by static shock. If there is an excess of static shock on your body, touching a circuit could damage it. Grounding yourself removes the static shock from you so that it is safe to touch the circuit.

Will a ceiling fan work if it's not grounded?

Yes, the grounding of equipment is for safety reasons not operational reasons. By grounding equipment, the conductor, if the equipment develops a short circuit to ground, supplies a low impedance return to the distribution panel where is is sensed by the circuits breaker. Once the breaker senses this short circuit current it will trip the circuit open.

What is the purpose-of grounding an outlet?

The purpose of grounding an outlet is for personnel safety. In electrical single phase installations the ground wire is used to carry a fault current back to the distribution and trip trip the breaker of the circuit that the fault was on. Without this ground wire a person could become the ground and receive a sever shock.

What is purpose of grounding conductor?

The groundING conductor is usually the safety ground which serves as an emergency current return path in the event of a circuit fault or overvoltage. Like the groundED conductor, it too is grounded at the service entrance, but is also connected to metal surfaces and parts along the circuit, groundING them. It conducts current only if the current "seeks" to return to the service entrance along a path other than the Neutral (like through your chest, should a Hot wire becomes loose and contact metal in the circuit that you may touch). Since the grounding conductor doesn't normally carry current, its cross-section is sometimes smaller than the groundED conductor's. The grounding conductor's insulation is green (no other conductors can have green insulation) though sometimes it is bare copper. Sometimes the steel metal conduit enclosing the Hot and Neutral acts as the grounding conductor.

Why is it that some electrical plugs only have two pins?

Double insulated appliances and lamps do not have a grounding circuit or pin on the plug.

What is the purpose of grounding electrical equipment?

It is a safety measure for devices that have a metal case where a failure in the device could cause the case to be connected to the hot side of the circuit. By grounding the case the breaker will trip instead of you getting a shock.

How do you use a voltage meter to find a short circuit?

You don't. What you can use is the resistance scale on a VOM. If the circuit has a reading of zero ohms to ground then it is very likely that the circuit under test has gone to ground. This grounding of the circuit is what caused the short circuit. Find the short circuit before re-fusing or turning the breaker back on.
