What is caused when the hot wire and either the neutral or ground wire make contact?

A short circuit. If things are working as they should breaker will trip or fuse will blow.

If live is kept open could it trip circuit breaker by connecting neutral to ground?
I would think not. However, if live were to come into contact with either the ground, or the neutral or both, this would cause a breaker to trip.
HOW DO YOU DISCHARGE ELECTRICITY?
If you touch the charged item to the ground, the charge will go into the ground. This is because static electricity is caused by either having too many or not enough elecrons. When toughed to the ground, the item will either get rid of the electrons or pick more up, making it neutral.
Can you connect a ground to a neutral bar?
In any distribution panel there are individual bars for each termination. The ground buss is in direct contact with the metal enclosure. The neutral is isolated from the metal enclosure. The only place where the two come into contact with each other is where a bonding screw protrudes through the neutral bar and into the metal enclosure.
Could anybody help the reading between earth and neutral in the incomer supplying power to the house is 120V while live and neutral reads normal 220V and live-earth reads up to 298V.?
It sounds like either you have a bad ground connection or that ground and neutral are NOT bonded at the main panel only. There is either a strap or screw in main panel that connects ground and neutral. Also check the connection to a ground rod and that the ground rod is intact.
How do you tow a 1999 Jeep Wrangler 4x4?
Either all 4 wheels on the ground with the transmision in Park and the transfer case in Neutral, or on a trailer.Either all 4 wheels on the ground with the transmision in Park and the transfer case in Neutral, or on a trailer.
What is the difference between the neutral and ground bar?
In any distribution panel there are individual bars for each termination. The ground buss is in direct contact with the metal enclosure. The neutral is isolated from the metal enclosure. The only place where the two come into contact with each other is where a bonding screw protrudes through the neutral bar and into the metal enclosure.
Why neutral wire doesn't give electric shock?
The neutral wire doesn't give an electric shock because it is the same potential as ground. That being said if you come in contact with the "hot" wire and the neutral or ground wire, you become the load and will receive a substantial shock.
Why in electrical wiring you need both neutral and ground if neutral is zero voltage why you cannot used it as a ground?
The neutral is a current-carrying conductor, the grounding wire is not; it is for safety as an ALTERNATE path to ground. For example, if something happens to disconnect the neutral or if the hot side comes into contact with conductive portions of an appliance, the grounding conductor can save a life by providing a safe fault mechanism.
What cause current on the neutral line in a three phase?
Current on neutral in a multi phase system is caused by imbalance between the phases. Question: Are you talking about neutral or ground? The two are very different. Although neutral is grounded, it is expected to be a current carrying conductor, so current on neutral is normal, so to speak. Ground, on the other hand is a protective circuit that is not supposed to have any current on it at all.
What is the reading ground to neutral?
Ideally ground and neutral should be at the same potential, but as there is current in the neutral wire and no current (normally) in the ground wire there can be a difference. I have personally measured over 25 VAC on the neutral relative to ground in some systems.
Whatcould cause a sq d arc breaker to trip when aregular breaker doesn't?
The neutral is in contact with the ground at some point of the circuit.
Can neutral and ground wires be connected to the same buss bar in a service panel?
No. The sub panel is wired that same as an ordinary three wire load. The three wire is connected the sub panels terminal points as red to L1, black to L2, white to the neutral bar and the ground wire in the cable set to the ground bar. The one thing that has to be done is the bonding screw that bonds the neutral bus to the panels metallic enclosure has to be removed. The electrical code states that there is only one place that the ground is joined to the neutral bar and that is at the service entrance point into the main distribution panel.
