Sizing a Generator - How to Determine What Size YouNeed

Getting a generator that can handle all your power generation needsis one of the most critical aspects of the purchasing decision.

Whether you are interested in prime or standby power, if your newgenerator can't meet your specific requirements then it simply won't be doing anyone any good because it can put undue stress on theunit and even damage some of the devices connected to it.Unfortunately, determining exactly what size of generator to get isoften very difficult and involves a number of factors and

considerations.

Making a choice amongst single phase, three phase, kW, KVA, welder,standby or motor starting generators can be mind-boggling. To prevent such confusion, this article was developedto help you get a better idea of how the sizing process works and some key things to keep in mind. This is not asubstitute for a certified electrician, which we always suggest talking to before buying, but it should provide youwith enough information to get a solid understanding of some of the key things that are involved.

Generator Size Variations: With the latest advancements in the field of electrical engineering, generators are

now available in a wide range of sizes. Generators with power supply capacities of 5kW to 50kW are readilyavailable in the personal and home use markets, while industrial generators are anywhere from 50kW to over 3Megawatts. Handy and portable gensets are available for homes, RV's and small offices, but larger businesses,data centers, buildings, plants, and industrial applications need to use the much larger sized industrial generatorsto meet their higher power requirements.

Generator Sizing - How Much Power?: Many people believe smaller

generators can be used for standby electric power because they are not running all the time. This is not only a myth but can actually be verydetrimental. Unfortunately, generator under sizing is one of the most common mistakes committed by buyers. Not only does it involve therisks of damaging your new asset (the generator), but it can alsodamage other assets connected to it, create hazardous situations, andeven limit overall productivity of the unit and/or the business relying onit. If nothing else, the key thing to remember here is that more is

always better than less.

How to Determine the Right Size Engine or Generator: Whilethere is no substitute for having a certified electrician perform an inspection and calculate everything for you, the

guidelines below do offer some great starting points and should at least get you started in the right direction:

Know Your Requirements: Going to a dealer and buying the best or cheapest generator available without anyother consideration is clearly not the best approach. It is always better to delve deep into your power generationrequirements before making a choice. You can do this in the following ways:

- Make a list of the items that need to be powered by the generator- Make a note of the starting and running wattage of the respective items- Calculate the total power requirements in KVA or KW

How to Find the Starting and Running Wattage: Getting the right starting and running wattage of thedevices you intend to power is crucial for calculating the accurate power requirements. Normally, you will findthese in the identification plate or the owner's manual in the buyer's kit of each respective device, tool,

appliance, or other electrical equipment.

Ampere - Watt Conversion: You may often find power requirements of tools stated in amperes. In order toconvert the power requirement of a tool from ampere to watts, follow these calculations, or you can also use ourhandy conversion tool on our power calculator web page.



For resistive load: Wattage = amperes x volts

For reactive load: Wattage = (amperes x volts) x load factor

Power Requirement Charting: It often happens that you lose the owner's manual or for some reason can't findthe power requirement specification of the tools and/or other electrical devices you're running. Here is a sample

power consumption chart that demonstrates some of the typical wattages used for common appliances and tools.

The chart is simply provided as an example to demonstrate how starting and running wattages differ, and howeach device has specific consumption needs. If you have questions over any particular items you can contact themanufacturer, consult an electrician, or contact us for a free consultation.

Different ways of Calculating: Depending upon the type and number of devices, and the way the generator is

scheduled to be used, there are a few different ways of calculating power requirements:

- Single motor running- Multiple motors running simultaneously

- No electric motors.

Advantages of choosing the right size generator: Now that you have an idea on how to choose theappropriate size of generator to suit your needs, here's just a few of the benefits obtained by going through that process:

- No unexpected system failures- No shutdowns due to capacity overload- Increased longevity of the generator- Guaranteed performance- Smoother hassle-free maintenance- Increased system life span- Assured personal safety

- Much smaller chance of asset damage

Where to Buy & Role of Dealers and/or Service Providers: Since you are not only purchasing a substantialcompany asset, but most likely an item you will need to rely on for prime or emergency electrical power at somepoint, probably in a crisis, deciding where to buy is also a key consideration not to be overlooked. The seller's

years of experience, whether they are a full service dealer or small commissioned broker, and so forth, all play a

role.

Having been in the business for nearly a quarter of a century, here's just a few of the reasons why you shouldalways consider Diesel Service & Supply, Inc. as your first stop for all your industrial power generation and diesel

engine needs:

SELECTION OF CABLE:

To know how much current a load is drawing, you must know Ohm's Law. You must also

need to know what the voltage is and the resistance of the load.

Before discussing this question, I would like to share few things regarding the information, I

got from the webs. When I search the different kind of answers for this question, I finally

satisfied from sir Kevin Boone's (UK) explanation. I can share that information.

Topic is selection of cable, selection of protection device for a circuit etc.

Several steps are there, we can see one by one:

Step 1: Find the nominal current for the given load. For eg., if you choose 5kw load, the

nominal current for such load is 5000/230 = 21.7 ~ 22A.

Step 2: From the nominal current, we can choose a MCB of rating 30A. (should be greater

than the nominal current, so it could be next available MCB)

Step 3: Selection of cable should withstand the nominal current. In which one should keep

in mind that we should consider the type of installation of the cable. Because the rating of

current for the cable can be vary according to the installation. For eg., installing the cable

inside the wall or trunk or any other strong insulation or through the open air. The cable

which installed open in the air can withstand more current when compare to the cable

which installed inside the wall. So for simplicity, we can assume the cable is installed inside

the wall (generally this kind of installation is followed by most of the engineers). When I go

through the manufacturer table 4mm 2 cable installed inside the wall can carry current up-

to 25A. So it is suitable for our load.

Step 4:Now for our 5kw load, 30A MCB & 4mm 2 size cable are selected. But keep in mind

the surrounding temperature should be consider. Since the current rating for the cable

could be vary to the temperature. Normally the installation is designed for 35 degree to 40

degree Celsius. Let us consider the ambient temperature is 35 degree. So under 35 degree

Celsius the 4mm 2 cable's correction factor is 0.94 (IEE wiring Regulations 2001). So the

current rating of the cable under 35 degree Celsius is 25 * 0.94 = 23.5A. It is satisfied to

withstand for our 5kw load.

Step 5: Voltage drop should be taken in account. Normally voltage drop could be up-to 9.2

V (4% from the rated voltage) is allowed. Let us assume from the distribution board to the

load, the total cable length is 20m. From IEE wiring Regulation table 4D2B: the resistance of line & neutral per meter is 0.011 ohms. So for 20m length it will be 0.011 * 20 = 0.22 ohms.

The voltage drop is 22A * 0.22 ohms = 4.84V. So it is well suited under 9.2V. Hence our

selection is correct.

CONCLUSION: For our selected load 5kw, 4mm 2 cable with 30A MCB is the good choice.

» Flat Submersible Cables 3 Core

3 core flat submersible cables is a specialized cable used for submersible pumps in a

deep well. As the area of installation is physically restrictive, and the environment is very

hostile, we design and manufacture keeping in mind these factors to achieve the highest

possible degree of reliability & safety. Certain striking features of our Flat Submersible

Pump cables include excellent resistant to moisture, abrasion, grease, oil, longer flex life,

excellent mechanical & electrical properties.
