Your house runs nowhere near 200 amps, so you need to make a list of appliances and fixtures that you use, or that you will need while the generator is running, and add their power consumption together. Add some extra capacity for growth and so the generator is not always at full power. Then talk to dealers about generators with the amount of power you need.
To run the house on a generator with the same capacity as the service that you have in your house you would need a 50 Kilowatt generator.

I = W/E Amps = 50000/240 = 208.

If you plug a generator into your house what will happen?
You have it the wrong way around, you plug the load into your generator. Never plug a generator into a house unless you have the proper disconnect installed. To do so will put you and your house in danger. Plus you are a danger to anyone working on the main line supplying power to your house. Things that could happen. 1 You could feed power to the main line which can kill or injure anyone working on the main line. 2 Without the proper control switch. You could be subject to large fines. 3 If the power company finds out. They could pull your meter. Taking your house off the grid. 4 You will be liable for any damage you cause. Also your insurance could be canceled. 5 If power comes back and back feeds your genset. It will turn into a smoking pile of junk. 6 If you need a generator at your house. Have it installed the proper way by a company that does installs.
How many amps does a 18000 watt generator provide at 120 volt 3 phase service?
The equation for power in a three-phase system is given by the following equation:P = 1.732 x line voltage x line current x power factorSo, to calculate the line current, we can manipulate this equation, as follows:line current = power / (1.732 x line voltage x power factor)As you make no mention of power factor, we shall assume the power factor is 1, and we also need to assume the 230 V you quote is a line voltage, so we can calculate the value of current as follows:line current = 18 000 / (1.732 x 120 x 1) = 86.6 A
What are branches of electricity?
There are many branches or jobs dealing with electricity. Some jobs are electric power generator operators, power distributor and dispatchers, and line installers and repairmen. There are electrical technicians, electrical engineers, and meter readers as well.
Can one run a cord between a 5000W Powermate generator and a 240V garage outlet to power a few lights a fridge and TV during a blackout?
Never do this! This may work (depending if your generator is delivering 110/220 or straight 220). However, this creates a severely DANGEROUS situation to the line workers - the people that are restoring your power during the blackout. This is a straight textbook example (i'm a 3rd year Electrical Engineering student). I'll give a quote from my textbook: 'Unaware of the [generator], the line technician believes that there is no voltage on the line. However, because of the [generator], 7200V exists between the two points, and the line technician could be seriously injured or even killed if he comes in contact with this high voltage.' The line worker sees 7200V because the 110 V goes through a transformer (the often green boxes on the street where wires are underground or the 'cans' on telephone poles). Thus this is a SEVERE violation of electrical code. The proper way to do this is to install what is called a transfer switch. There is a display of a setup at the Home Depot where I live. I suggest visiting them and talk to someone in the electrical department. Of course, if you were just concerned about keeping the fridge running, you could use an extention cord connecting your generator to the fridge. Why not turn off the main breaker switch to protect any linemen? The correct and legal way to do this is to install a generator transfer switch. It has a male plug to connect to the generator so you're not using any highly dangerous male-male dongles. It also allows you to switch circuits between generator and line power when needed and usually has a meter so you can tell when you overload your generator.
Are you liable if your tree causes a power surge inside your house after rubbing a power line in the yard?
Liable? No. But you may want to get your tree trimmed so that it does not happen again.

What condition must be met in order for an alternator to deliver power to a power line?
The generator has to be synchronized to the power line before it can be connected. If connected out of phase there is a chance that the generator will motorize and this could break the crankshaft of the prime mover.
What is a good way to harness reliable electric power generation, for the residential home?
I would recommend a generator or storing battery. By using solar power in the summer months and storing it for later as well as a gas generator. There isn't a good way to harness electricity outside of the main line, but using a generator to fill in the times when the power goes out would be a good idea.

How to wire 4 prong generator plug?
Answer for USA, Canada and other countries running a 60 Hz supply service.Stop! What...? Don't try to do that...!Don't make a cable with the intention of plugging a generator into an outlet in your house, it is incredibly dangerous!Power from your generator will back-feed into the power lines, posing a severe unexpected shock hazard to any line-workers who may be fixing the lines - the very same reason you are wanting to use your generator!Plug your appliances directly into the outlets on your generator. If you want to power the outlets in your house from the generator you must do it right and install a proper 'generator transfer switch' at the main incoming breaker panel which is situated where the main electricity service cable comes into your house.As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.
How do you calculate 3 phase power factor?
The power factor for a three phase generator is 80 percent. The generator consumes 36 kilowatts and a line to line voltage of 400 volts.
What is the load rejection and load pick-up in the power generation?
Load rejection occurs when load is suddenly removed from the generator. The most obvious example of this is the breaker connecting the generator to the power grid opens. This results in a full load rejection. Load pick up means the generator is supplying power to a given load. When a generator comes on line, it will pick up some load that might have been supplied by another generator.
How many amps per phase does a 100 kva 525 volt generator give 50Hz?
I think you mean, 'How many amperes per line does a 100-kV.A, 525-V, generator supply?' The wires that connect a generator to its load are called LINES, not phases.The equation for apparent power is: Apparent Power = 1.732 EL ILSo you simply rearrange the equation to find the line current (IL).

Connect Natural Gas Generator For Home Into Gas Line?
You can connect a natural gas generator for home into your existing natural gas line. Doing this saves you the hassle and time of buying gas and filling the generator. This also ensures that your generator will be running constantly and will not run out of fuel. If a member of your family requires electricity for a medical device, this will ensure they are safe and comfortable during a power outage.
Importance of load characteristics of a generator?
I assume this is asking about the capability curve of a generator. A generator can only produce so much actual power (kW) at a specific power factor. As power factor changes, the amount of current flowing that is due to reactive power will also change. The total current Ix (reactive power) + Ir (real power) will cause heating in the generator, and so the generator can only kick out so much current, be it real power or reactive power. Reactive power is used to control the voltage (drag it down, or push it up) and change phase angles to push more power down specific lines. If the load on a generator is such that it's expected to generate power outside its' capability curve, terminal voltage may begin to sag (which will cause the generator output power to be less, potentially exacerbating the problem), or may float too high (potentially damaging equipment). Excessive heating in the generator can also result, and protective devices may kick in to trip the generator off line.
What is an offline ups?
In an on-line UPS the load is always being powered by the UPS and it is constantly charging so there is no switchover time. In an off line system, the system detects the lack of voltage and switches to the alternate source of power. Usually this would be a generator that would start after a short period of no supply voltage. Some critical systems would use a short duration direct system with backup generator kicking in after a short period.
