Basically, the same as if you had a short to neutral, since the neutral and ground are tied to the same bus bar in the breaker panel. The breaker should trip, or the fuse should blow. Supply of voltage then stops.

The difference between short to a voltage circuit and short to a ground circuit?
A short circuit is an abnormal connection between two nodes intended to be at different voltages. A voltage circuit is caused intentionally for the purpose of voltage sensing. A ground circuit occurs between a phase and the ground.
What is the formula to calculate the line to ground voltage of 480v?
If by "line" you mean a wire conductor carrying 480volts AC then there can be no "line to ground voltage" or you would have a short circuit!Ground voltage, usually referred to as "Earth" in electrical terms, is at zero potential and thus connecting a live 480 AC line straight to Earth is extremely dangerous and unless there is a means to cut the voltage when a short occurs (in a house this will be the fuse box, these days usually containing RCB's) an electrical arc at temperatures hotter than the Sun will be produced at the point of the short, the rest of the wire will get so hot it melts and the thermal damage will spread to other wires or any combustable materials in the nearby vacinity and a raging fire could easily ensue!There are tables giving the electrical breakdown resistance of the insulation used on electrical cables (Typically measured in kv per mm) and perhaps this may be more helpful to you.AnswerOf course you can have a line-to-ground voltage! If the line conductor has a potential of 480 V measured with respect to ground, then there is a line-to-ground voltage of 480 V. Period! End of story! The very presence of a voltage between a line conductor and ground indicates that there is NO short circuit, as the voltage across a short circuit is zero! But to answer the question, there is no calculation involved. But you can measure it with a voltmeter.
Can Wiremold be use as a ground in short runs?
No. The individual pieces are not classed as a continuous raceway. A ground wire has to be installed from the source voltage to the load to comply with the electrical code rules.
How do you describe lightning?
Lightning is the occurrence of a natural electrical discharge of a very short duration and a very high voltage between a cloud and the ground.
What is the voltage across any short circuit?
zero.........
The difference between short to a voltage circuit and short to a ground circuit?
A short circuit is an abnormal connection between two nodes intended to be at different voltages. A voltage circuit is caused intentionally for the purpose of voltage sensing. A ground circuit occurs between a phase and the ground.
What is indicated by reading of battery voltage on the ground side of component?
That a short to ground exists in the circuit.
What is indicated by reading of battery voltage on the side of component?
That a short to ground exists in the circuit.
What happens when any phase conected to ground?
You get a short circuit.
What happens to the voltage values of other resistors when a short occurs in one of them?
If a short occurs in a resistor in series with other resistors, the voltage drops across the other resistors will increase. If a short occurs in a resistor in parallel with other resistors, the voltage drops across the other resistors will decrease, to zero.
What does ground do on a three prong plug receptacle?
The ground blade on a three blade plug (cap) is to provide a low impedance return to the voltage source. If the portable equipment develops a short in its circuit and goes to ground, it is this blade that will carry the short circuit current back to the supply distribution panel and trip the breaker open to cut off the supply voltage.
What happens if a circuit has no resistance?
Then the voltage in will equal the voltage out. The purpose of a resistor is to reduce the amount of electrical flow of current. You 'short out' the supply and blow a fuse/circuit breaker.
What happens to the ground in the tundra during the summer?
During summer, the ground in tundra thaws and becomes soggy and wet. The cycle of freezing and thawing, crushes plant roots. This, in addition to cold temperatures, high winds, and short growing season, limit plant heights.
What is a short to voltage?
what is short to voltage in a car electrical circuit & how to check it ?
What makes the voltage gauge fluctuate when the turn signal is on?
A short in the turn signal wiring can cause the voltage gauge to fluctuate. A loose ground wire can also cause the gauge to fluctuate.
What does PQ and OR PD designation mean for an electronic part on a laptop motherboard?
PQ are voltage regulator chips for protection that ground voltage if short circuit is detected. Don't know what is PD
