Arcing Grounds is a phenomenon which is observed in ungrounded three phase systems. In ungrounded three phase systems operating in a healthy balanced conditions, capacitances are formed between the conductors and ground. The voltage across these capacitances is the phase voltage
Some voltage must be present but the current causes the arcing.
It's common to put arcing horns on the HV side of a power transformer to short out voltage spikes arriving from lightning strikes along the line.
Please rephrase the question. Are you describing an electrical furnace or the welding process?
The question isn't correct, you have to define the voltage level not the power rating.
Voltage on ground can mean an open ground. It can also mean (high) current on ground, due to a ground fault such as reversed neutral and ground.
The jackknife is a particular body position, arcing the body forward towards the ground with the legs straight and feet on their toes. The floating refers to the use of a floating bar to hold the body up off the ground for shoulder presses.
Some voltage must be present but the current causes the arcing.
A shorted coil or shorted coils in the rotor will cause arcing at the commutator. It should also be noted that if the brushes are damaged badly enough where they make contact with the commutator, this can cause arcing. Oh, and let's not forget that a stuck brush or brush spring will prevent a brush from making proper contact with the commutator. Arcing can result from that, too.
Arcing is electrical current jumping across a gap, or creating an arc, as in a spark plug firing, or lightning arcing across the sky.
Look for arcing from the plug wire, if the wire is bad the spark will jump to the easiest path to ground, skippjing the plug completely.
The result is that the hot wire comes in contact with the neutral wire or ground. This can happen by a mechanical accident, current arcing over an air gap, a conducting liquid that provides a path from hot to ground or perhaps a person mistakenly creating a path between the hot and ground with his/her body or a tool of some sort.

high voltage breaking capacity
You have a wire that is loose and arcing.
Arcing is caused by a poor electrical connection. The breaker is not making good contact with the buss bar. Try replacing the breaker.
Always push start your car.
An arcover is the unwanted arcing of electricity from one component to another.
