How do you tell if a wire is shorted out?
If by meaning wire as a circuit, when turning on the circuit the fuse will blow the circuit open, or if the protection is a breaker, the breaker will trip. This is all on the conjecture that there is a return path for the current to flow. This is the main reason for ground wires on all equipment, to provide a return path for the current to flow back to the source.
Does the green ground wire have to be grounded to the stove?
Yes, the ground wire should all ways be connected. This is the short circuit current return path that trips the breaker in case of a short circuit in the unit.
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.
When you turn the house lights on the breaker blows why?
Ok, lets assume that these are not newly installed lights or lights added to this already existing circuit first what type of lights are they? the reason I asked is because if they are fluorescent lights it could be a faulty ballast. if it's regular light bulbs then they are several things to look for. how many lights on this breaker? have you placed a higher wattage bulb in these lights than recommended? what is your combined wattage? a 15 amp breaker is rated to supply power safely up to a maximum of 1440 watts. add up the wattage of each light bulb including any outside flood lights or outlets also on this circuit. If the the total is under 1440 watts then first replace the breaker with the same wattage rating then turn each light one at a time and wait to see if the breaker trips again. If it does, check the last light you switched on. Answer for USA: Never load a breaker to its full rating. The law allows only 80 percent of the breaker rating. That's the 1440 watts for a 15 amp breaker, and 1920 watts for a 20 amp breaker. Also look for a load you might not think is on the breaker, such as an outdoor light, or something in a hall or another room. Other causes: - A motor draws more current when it starts than when it runs. - An aging breaker, or one that has been overloaded too many times, can trip at a reduced current. If this is the case, it needs to be replaced.IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.If you do this work yourself, always turn off the powerat the breaker box/fuse panel BEFORE you attempt to do any workANDalways use an electricians test meter having metal-tipped probes(not a simple proximity voltage indicator)to insure the circuit is, in fact, de-energized.
What is the difference between a ground fault breaker and a gfci outlet?
A ground fault breaker is installed in the distribution panel and every device that is connected to the breaker in that circuit is protected. A GFCI receptacle is installed in a outlet receptacle box. They can be wired two ways. Direct wired will protect just the outlet of the box that it is mounted in or (in - out) wired where the GFCI receptacle protects all of the down stream ordinary receptacles in the circuit.They're the same thing."GFCI" is an acronym for "Ground Fault Circuit Interrupter". It "interrupts, or "breaks" the circuit if there is a ground fault.A ground fault is defined as any condition in which current goes somewhere other than the return wire. The GFCI constantly compares the current through the "hot" wire to the current returning through the neutral wire, and if there is any significant difference in the two, the GFCI interrupts the current, potentially saving lives.
How long is the main ring?
If you are talking about an electrical ring main it can be as long as you want it as long as it returns back to the circuit breaker with the other end of the cable, which if you didn't return the 2nd end of the cable to the circuit breaker you would have a radial circuit.

What is the earth wire inside a plug for?
This wire provides a low impedance return path to the distribution panel in case of a circuit fault. This direct fault current path will trip the circuit's breaker and open the circuit.
What is a circuit breaker in tax preparation?
what do you mean? a circuit breaker is a device usually used in domestic fuseboxes and appliances, that when a circuit current (amount of amps) is higher than the current set to the breaker as the trip current, the breaker will trip, preventing the wire from overheating and possibly shorting out (see internet) which might cause bigger problems. the breaker may also trip if a short occurs. but tax preparation... i'm afraid i am not even familliar with the term : / i have a feeling though that in "tax preparation" it might be a metaphorical term. i hope the first part helps though! if you have any more questions... just ask! :D
How do you hook up wire from ansul system to shunt trip breaker?
You would need to take the "input" wire for the shunt trip breaker to an electrical switch (not alarm initiating switch, which are DC voltage rated) within the Automan unit and connect to the "Common" connection and the "return", the wire to the actual shunt circuit of the breaker, from the "Normally Open" connection of the switch. When the unit activates, the switch will be placed into "Closed" position, therefore completing the circuit and activating the shunt coil.

What is the problem if the breaker isn't tripped and there is no power to my switch in computer room switch in foyer switch for outside porch and alarm panel is dead?
The most likely problem is that the breaker has tripped. On some breakers there is a indication window that shows a red flag if the breaker needs resetting. On other breakers there is no indication but a slight misalignment of the breaker handle as compared to the other ones. On the distribution panel find the breaker number of the circuit that is off from the panel index. Push the breaker handle to the furthest off position that you can. As the handle is moved to the off position you will feel a bit of resistance. Push past it as that is the breaker resetting. Return the breaker to the on position to see if the circuit has re-energized. The only other reason is that a wire has become disconnected in the circuit. If you have been doing any electrical work on the circuit start looking in that area. To troubleshoot these types of problems it will require the use of a volt meter to check to see if the circuit is "hot" from the breaker out. Then it is just a matter of finding where the voltage stops and locate the problem.
What is a rccb?
A residual-current device (RCD), or residual-current circuit breaker (RCCB), is an electrical wiring device that disconnects a circuit whenever it detects that the electric currents not balanced between the energized conductor and the return neutral conductor.
How the use of the neutral wire provides three different sources of electrical energy?
It is the ground return for the two different phases of your AC supply line providing 115 volts between it and the red or black breaker supply lines in your breaker box. For 230 volts the common is not connected and the red and back lines supply 230 vacfrom breakers
Why is it good to a ground on a receptacle?
Not only is it good to put a ground on a receptacle it is mandatory by the electrical code rules. The ground is installed to provide a low impedance return to the distribution panel to trip the breaker supplying the circuit in case of a ground fault occurring on the circuit.
