In order for a neutral to become live, its connection to ground must be severed. This is dangerous, and must be fixed. In the worst case scenario, with all grounds open, a typical 13.2kV distribution circuit running a 120/240V transformer can generate 7.6kV to ground. That is a LOT more than 120V, which is the US NEC limit for any conductor in a home relative to ground. Besides being an electrocution hazard, this can destroy nearly all electrical devices in the house. It is also possible that a wiring error exists. This is also dangerous and must be fixed.
If the meter has 208-240V coming to it, no the neutral doesn't go through the meter. If the meter has only 120V incoming power such as many RV parks then the neutral does go to the line side of the meter or it won't work.
Disconnect the supply with the help of utilty personnel and then start lowering it.Please see that the cable/wires are sufficient for the new location.
Switch for neutral broken or not in correctly. It may operate a relay. Find it and see if it comes on and off with you switching the machine out of neutral and back. If it is fused check that. You can put your meter across the open fuse and watch the meter as you switch.
It is connected across the hot and neutral if it's voltage is 120 volts. There are two terminals on the back of a panel mount frequency meter. Line voltage to one terminal and the neutral wire to the other terminal. The working voltage will be on the meter's nameplate which is usually located on the side of the device.
There should be no ground wire in the meter stack from the mast head to the meter base. If the meter base to distribution panel conduit is PVC, then a green grounding conductor must be pulled into the conduit. This green wire is independent and isolated from the neutral wire and should never be terminated together at this point. Only the line service conductors and the neutral wire go through the meter base. The neutral goes through a lay in lug. This type of lug requires the insulation to be stripped of of the wire where it passes over the lug. This stripped wire is then laid into the lug and is secured to the meter base by the removable top piece of the lug. The neutral wire remains unbroken from the mast head to the distribution panel's neutral buss bar. Using this lay in lug the watt meter picks up the neutral wire for the plug in meters operation. If your terminology is not correct and you mean the "distribution panel" instead of "meter base" then the answer is no. There are two individual buss bars in the distribution panel. In some panels there may not be an actual "ground buss bar" but ground screws lined up in a row in the back of the distribution panel's enclosure. In all distribution panels there is a neutral buss bar where all of the neutral conductors from the branch circuits connect. Do not mix the bare ground wires and the white neutral circuit wires under this neutral buss bar.
One of the conditions that would cause this is that there is no supply voltage to the top of the meter. Another problem could be, the neutral tickler wire has become disconnected.
find your electric Meter and you've found the point of entry, or depending on where the electric meter is in the building, you can trace the cable back from the meter to the point of entry.
A clamp-on meter works by measuring the magnetic field set up around a conductor. Because the currents in the line and neutral conductors flow in opposite directions, their fields cancel and the clamp-on meter has nothing to monitor. So it must be placed around either the line OR the neutral conductor -not both!
To calculate voltage drop to size the wire, a voltage must be stated.
It shouldn't. The open end of a non connected neutral should have the same potential as the voltage feeding the circuit. The only time a voltage will show is when the return neutral is tested with a meter to the neutral bar or the ground return bar. It will then show what the supply voltage to the connected load is. Once this neutral is connected to the neutral bar there will be no voltage shown across the test meter between the neutral and the neutral bar or the ground bar.
If the meter has 208-240V coming to it, no the neutral doesn't go through the meter. If the meter has only 120V incoming power such as many RV parks then the neutral does go to the line side of the meter or it won't work.
The main supply will first come from the power company to a transformer to reduce the voltage then from the transformer to the weatherhead then through the house meter to the main disconnect on the outside of building then to the switchgears main. The cable coming from the transformer to the meter and to the top of the main disconnect is the Main service cable
ohmmeter has it's own power supply
Answer for USA, Canada and countries running a 60 Hz supply service.The wires from the utility connection will be connected to the top terminals jaws of the meter base. The bottom of the meter base terminal jaws will be connected to the top of the first over current device. This will be the service distribution's disconnect switch. The neutral will pass through the meter base with no grounding connection and continue on to the distribution's neutral terminal point.
If the meter is sensitive enough and there is a resistance between the neutral and ground then the meter should be able to detect it.
It is connected to the cut out fuse which enables isolation of the circuit from the supply when there is a fault.Additional Information:The service cable is usually connected to a meter fixture and from there to the main electric panel which will have a breaker to isolate the panel.
it also depends on what meter you have, is it a KWH METER or a AH METER. IF ITS A KWH METER(KILO WATT HOUR) IT COUNTS IN WATTS (35w PER HOUR.)
