Is reversed polarity when the ground and the neutral are wired backwards?

Reversed polarity in ac wiring is when the hot and neutral are reversed.

the hot and neutral are wired forwards the ground and neutral are wired backwards

I am getting ready to take a inspectors test. and one of the things we have to do is look up some of the questions online did you get the answer to this one?

For safety sake, please do not attempt the above for real. Please don't cross wires. For connections, live should go to live; neutral to neutral; and ground to ground. No exception. The hot wire carries the AC signal, which reverses polarity every 1/120 of a second. Please refer to the related links. ==============================

I know the answer, but I'm not taking this test, you are! Study your book and learn the answer yourself. Believe me, I'm doing you a favor.

no, backwards walkovers are easiest however some people may learn a back handspring first therefor for them the back handspring would be easier...... isn't a back handspring just a flick??

If you are talking about an AC (alternating current) circuit, such as the house mains supply, "reverse polarity" usually means the "hot" and "neutral" wires from the supply have been connected to something the opposite way round to what they should be. If you are talking about a DC (direct current) circuit supplied by a battery, such as in a car, "reverse polarity" usually means the positive and negative leads from the battery have been…

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.

Because if you reversed the polarity at the battery it would blow the fuse through which current flows to the drain.

The danger of a 120V socket with reversed polarity is that some appliances are designed to minimized the chance of a user coming into contact with the hot terminal of the line. This is done by polarizing the plug, making one blade wider than the other, the narrow blade being hot. In a lamp fixture, for instance, the hot side would connect to the center pin, while the neutral side would connect to the shell…

There is an open circuit on neutral. You should have power between hot and neutral, as well as between hot and ground. Note well, however, that you should not pull any power between hot and ground, because ground is not intended to be a current carrying conductor - it is only there as a protective earth ground in the case of fault. You can not easily tell, at the outlet, if neutral and ground is…

I will assume that your question is in reference to CT and transformer polarity. In the case of a CT (Current Transformer) they have to be installed in the correct direction for proper metering. The polarity check is used to verify that they are installed correctly and that the polarity marks are correct (if the CT has them). In the case of a transformer there are two types of polarity, additive and subtractive. If you…

reverse polarity is wiring. This is hot wiring from an outlet. Another Answer If you ignore the protective (earth/ground) terminal, there are two 'live' terminals at a socket outlet (receptacle) -the line terminal and the neutral terminal . The 'neutral' terminal is roughly at earth (ground) potential, while the 'line' terminal is at a potential of 230 V (Europe) or 120 V (North America) with respect to the neutral terminal. It's very important that the…

The neutral of a transformer is usually grounded. Under this situation, this question is the same as asking whether you can apply a voltage to ground; the answer is yes, but I don't know why you'd want to. Sometimes transformer neutrals are insulated away from ground. If this is done, then you could inject "backwards" from the neutral up into the transformer. Again, I don't know why you would want to do this, though.

no, you ground the neutral

For a US 3-prong plug, a smaller slot should be hot, the longer slot should be neutral, and the screw that holds the plate on should be ground. Cheap, inexpensive testers are available at hardware stores.

A -dim- "hot/neutral reversed" indication means that there is -some- voltage, but less than 120V, on the neutral line, referenced to the safety ground. Ideally, the ground and neutral should be at the -same- potential, but a loose neutral connection "upstream" of this outlet will cause measurable voltage between ground and neutral. No need to swap any wires; just tighten neutral connections at all points (including outlets AND breaker panel) on the same circuit as…

Most technical people believe that AC electricity is not polarized this is an incorrect assumption. Since AC power is just a potential difference between some reference (ground) and a signal it stands to reason reversing the Neutral and the "Hot" should reverse the polarity.

Circuit breaker tripping, or non functioning outlet. The neutral and hot can be reversed, or an open ground, and you will have no symptoms. This can only be detected with a circuit tester you plug in to check the wiring.

The only way to tig is to have your ground clamp hooked to the positive side of the welding machine. The negative lead will go to the tig torch. If it is reversed you will find out very quickly when you strike an arc. Most metals will be welded using this Polarity (straight). Most Aluminum TIG welding is performed using A C current.

It depends what you mean by 'polarity'. For a d.c. circuit, 'polarity' means correctly identifying the positive and negative conductors. You can use a d.c. voltmeter (or multimeter set to measure d.c. voltage), taking care to observe its polarity markings. If the instrument's needle moves upscale, then the polarity of the supply matches the polarity of the instrument. For an a.c. circuit, 'polarity' means that the line and neutral conductors are correctly identified. To do…

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.

The ground wire and neutral wire are not the same.

Neutral Ground Resistor is using for minimizing the fault current of system. It is a resistor which connected between ground and neutral and increase the resisting path for fault current.

A neutral grounding reactor is a reactor that is placed between equipment neutral and ground. These are often used to ground generators to limit ground fault current.

Negative ground

Lightning does not strike backwards, from the ground to the sky. It only moves in one direction, from the sky to the ground. By striking backwards, do you mean can the Earth give off a lightning bolt to the clouds? No.

Neutral is connected to ground at the distribution panel, and no where else. Any current flowing on ground downstream of the panel is considered a ground fault.

By National Electric Code only the Main Panel should bond ground and neutral. If subpanels have ground and neutral bonded, it could cause ground loops and shock hazards.

I own a 1948 John Deere B so I know for a fact that B's serial number 201000 and up have positive ground. Don't reverse the polarity cause it'll fry the generator and possibly the starter (the starter might even turn backwards - not sure cause I've always been sure to connect the batter with positive ground). The older B's should most likely be the same as 201000 and up. My dad told me that…

If you have to connect the neutral to ground to make the circuit work then you have an open neutral in your circuit. Be careful in handling the neutral as there can be voltage potential on the neutral if a load is connected. In a properly wired home that has been inspected by the local electrical inspector the neutral should be bonded to the ground at the main service distribution point. There will be a…

In your house 110 vac female plug, one connection to ground should measure 110 vac and also measure to neutral 110 vac-so ground and neutral are the same. :-

As i know,neutral is the return path of current & ground is for any leakage current

Neutral and ground are only bonded at the main panel, not subpanel.

The neutral wire should never be used as a ground wire. The neutral wire in some cases takes a convoluted path back to the neutral bar in the distribution panel. On a ground fault condition the path of least resistance (low impedance) is needed to trip the breaker as fast as it can. This is the purpose of the ground wire. Using the neutral path, this does not happen.

Ground wire can be appropriately bonded to the neutral and cabinet at the service box by connecting the neutral and ground wires from the feeder wires to the neutral bus bar and the ground terminal located on the same cabinet at the service box. White wire (neutral) must be connected to bus bar and bare wire must be connected to ground terminal in the same cabinet.

There is normally no voltage on the neutral line because the neutral line is grounded. However, and this is always important, do not assume that neutral is grounded, nor that there is not an elevated voltage on neutral or ground due to a possible ground fault.

No, the dryer must have separate ground and neutral lines.

What two colors may be used for the ground conductor (neutral)

There are two reasons one cares about polarity in AC circuits: safety and phasing. In a common household circuit, we are concerned with safety. One side of the AC line, called the "neutral", is at the same voltage as ground. This side of a common outlet is identified by the wider slot and plugs have a wider blade. In the wiring, the neutral is white. On wiring devices, the neutral wire connects to a silver…

A bare grounded neutral should never get close to the ground if it is wired properly. When the neutral leaves the meter base it is in conduit and should enter into the distribution panel where it connects to the neutral buss. It is at this junction that the copper ground wire is connected after coming from the outside ground rod or ground plate which ever grounding system was used.

the bare copper is always a ground

You'll have to explain your problem better.If HOT black and Neutral White in your house wiring are both hot then Neutral is NOT bounded to ground in main panel and neutral could be floating. There should be no voltage between Neutral and Ground (Bare wire in panel). By code if there are multiple panels Ground is only bonded to Neutral in th emain entry panel. I have seen cases where this bonding was not done…

It may be the GFCI breaker is defective. Make sure it is wired correctly. Neutral to neutral bar and ground to ground bar.

Just checked and it does have a ground connection.

No, the ground cable gets always disconnected first and connected last, regardless of ground polarity.

In standard residential wiring there is a black (hot), white (neutral) and bare wire (ground). There must be a neutral, so not sure what you mean. The neutral and ground are bonded to each other at the main electric panel.

The water pipe is not properly grounded AND there is a ground fault or neutral imbalance in the house. Alternatively, there could be a neutral problem. In an ideally balanced house, the current on one hot leg balances the current on the other. This means that there is no current on neutral. In practice, there is some imbalance, and that common mode current does flow on neutral. If a circuit has a ground fault, the…

If there is a GFCI in the circuit it will stop working correctly. They compare ground current to neutral current to detect a fault. It makes ground current equal to neutral current which is a fault condition.

When the neutral is connected to the ground they are at the same potential which is zero volts. If the neutral gets disconnected from the ground then a potential of 120 volts will be measured from the open neutral to ground. This voltage is being measured from the neutral side of the load that is on the circuit. because they are actually the same cable at sub station, but split by the time they come…
