Also, buy a generator transfer panel if you plan to power your house off a generator. It's the law.MoreNot because it's the law, but if you don't have a transfer panel and you connect it directly to your panel you'll also be putting current to the lines coming into your house.
This is real scary for the electricians that come out to repair the power. The (city) power is off and they don't expect to see (feel!) any on your end. You could end up electrocuting someone.
lets take an e.g. to answer it try to connect your neutral wire to earth .you will get exact 210-220v This is because neutral is not exactly at zero due to the Resistance of the wire from source to our home. now if we connect the neutral to earth the neutral become exactly zero and we get full supply.
Your 20-Amp panel would need its own 20-A "main breaker", probably in 240-volt, 2-pole configuration. You wire the black and red in the generator cord to the two circuit breaker poles, the white neutral to the neutral bar in the subpanel (which must remain ISOLATED from the metal panel), and connect the grounding wire to the grounding lug on the panel. Do NOT connect generator neutral to any grounding bar; neutral and ground can only be connected at the main (service) panel. All subpanels must have their own grounding rod as well, and the generator may need its own.
It means the neutral is not grounded.
The neutral of a generator should never get into a condition where is is floating. All generators have the neutral tied to the frame of the generator set. It comes this way from the manufacturer. If it is floating then someone has disconnected the neutral wire from the frame. Just reconnect the neutral to the generator frame again to stop it from floating. Larger generators should also have a ground rod connected to the generator frame for grounding purposes.
Yes, you can connect each appliance between one of the three live wires and the neutral. The generator must supply the correct voltage and have a sufficiently high VA rating.
Black & Red are hot, and White is neutral. If it has no place to connect neutral connect neutral to ground.
You cannot convert a 3 phase generator to single phase. If the generator is a 4 wire generator you can connect a single phase load between the neutral wire and any one phase wire. Just make sure the voltage of the generator and the load are the same. If you have what is known as a 12 lead generator. You can change the voltage and phase to what you need. But if it is a four wire 3 phase unit it cannot be changed. As the other poster stated.
very easy connect the live or phase to the marked on terminal and neutral which is necessary to the marked neutral
To create a neutral in the supply feed for lighting and other supply needing a neutral a neutral needs to be married at the source and divorced at the supply
What you need to define is the statement "utility- sized electrical generator". It depends on what the generators output is used for as to the way it is internally wired. In some configurations there is no neutral to ground as in a Delta configuration.If the generator is configured for a Wye output and the neutral centre tap is not grounded there will be a floating voltage between the generator and the utility system ground. It is for this reason that the generator's neutral point is grounded to bring the floating voltage down to zero volts to ground.
It should be zero.
hi... to determine the high fault current when the short circuit done at the output terminal of the generator... more information check any book of power element analysis and chapter (three phase fault at unloaded generator)... with my Greetings
There is no conversion. A three phase system comprises 3 lines. To obtain single-phase power all that's needed is to connect the load across any two of the lines... ------------------------------------------------------------------------------------------------------------------------------------------------------------- Not necessarily correct. There is more that needs to be known about the generator to do this connection CORRECTLY. The above statement is true IF the generator's output is compatible... meaning, it is a Y-configured output AND is at proper voltage. Y (neutral) of the generator's output, must be connected to neutral of your load. Your generator's output MUST be in the the same general range as your load!!! Let's say that your home is a common North American 240v single-phase load... you have two hot leads (L1 and L2) and one neutral. You have 120v between L1 and Neutral, 120v from L2 to neutral, and 240v from L1 to L2. If your generator is configured for 3-phase 240v DELTA, then you cannot 'directly' connect the 3-phase generator, because it has L1, L2, and L3, but no neutral... you'll have fried equipment inside your house. If your generator is a 208/125Y, it will have L1, L2, L3, and Neutral... where 125v exists from any of the Ls to N, and 208 between any of the L's. If your generator has an internal panel with additional connections to reconfigure it to different outputs (i.e 230v delta, 480/277Y, etc), then it's also possible to configure it for Double-Delta output (a way of yielding single-phase output from a delta-wound 12-wire generator. In short, it's be best to know more about the generator AND the load, before going further. There are excellent resources for these issues in generator and power forums online- a web search will quickly find them, and the people who know your generator and power system well.
Connect to the circuit neutral wire which should also be white.
A phase leg connects to the neutral through the connected load.
As far as I understand, you don't need neutral line for connecting appliances that is 3-phase compilant. You only need the neutral line to connect a single phase appliance, which you connect along with one of the three lines.
Yes, except that the correct term is 'line' conductor, not a 'phase' conductor.
remember the + side of the speaker basically means neutral, in all electric projects the - is always the live line, so if + means neutral that basically means that ground would also be neutral, speakers dont need ground, so if u wish connect + with neutral on the speaker.
prepare to fry
The neutral wire and power wire are never connected together.
Ground loop current, which is undesirable and every effort should be made to eliminate it.
A neutral wire is essential in a three-phase star (or wye) connected system supplying an unbalanced three-phase load. Without a neutral, the voltage across each of the loads may become unbalanced, too.
To bypass the cars neutral safety switch, you need to find the two wires to the safety switch and connect them together. It can also be done by putting the car in neutral.
