How to buy a generator and what are the required specifications?

Generators are sold in different sizes depending on the amount of power they can output, in other words, the number of devices and lamps they can run at the same time. Power is measured in watts, for example a generator with a capacity of 5000 watts, or abbreviated to say 5 kW.

How to calculate the required generator capacity?

Each electrical device has its own electrical need. For example, a lamp might need 35 or 100 watts, and a refrigerator might need 600 watts, and so on. Start by making a list of things that you do not want to dispense with during a power outage, then collect those capabilities and then buy the generator that has a capacity greater than the total capacity. Here are some rough numbers for common basics:

  • 3 Bulbs * 60 W = 180 Watt
  • 1 TV * 150W = 150 Watt
  • 4 Mobile Chargers * 5 W = 20 Watt
  • 1 Refrigerator * 600W = 600 Watt
  • Total = 180 + 150 + 20 + 600 = 950 watts

This means that you need a generator with a capacity of at least 1000 watts (kilowatts).

You must take into account not to run the generator at its maximum power for a long time, so it is better to exceed 500 watts over the total of your needs at least, for example here the total is 950 and you exceed them 500 and keep 1450 watts (note that generators come with fixed capacities such as 3000, 5000 and so on) You need a generator of at least 1500 watts.

How do you know the required device capacity?

Each electrical device, you will find a sticker on the back written on it the amount of its electricity consumption. You will find a number next to it with the letter W or the word Watt, for example:

Take into account emissions

Like most small-engine machines, generators produce large amounts of carbon monoxide (CO), so never, under any circumstances, operate the generator set indoors. You must take into account that the place is well ventilated, so that carbon monoxide does not accumulate in the place.

What is carbon monoxide (CO)?

It is a colorless and odorless gas, and when inhaled, the body deals with it as if it is oxygen and transfers it to all parts of the body and of course the brain, large quantities of it lead to coma or death.

* Many generators are equipped with carbon monoxide detectors that will turn off the machine before the carbon dioxide builds up to the point where it becomes lethal. Although the generator equipped with this method is a bit more expensive.

What are the symptoms of carbon monoxide poisoning?

  • Headache
  • Nausea
  • Difficulty breathing
  • Fatigue and exhaustion
  • Dizziness
  • Loss of consciousness

How to use the generator?

There are steps to start and stop the generator that must be followed so as not to cause problems either to the generator or the electrical devices connected to it.

To operate and use the generator, turn on the generator, then connect the plug that will transmit electricity to the home, then connect the electrical appliances.

* It is important to connect electrical devices one by one because there are devices that draw a large electric current than is needed at the time of operation, and if it happens that you connect more than one device of this type, they may cause a problem.

After completion, disconnect the electrical devices first, then disconnect the plug connected to the generator, then turn off the generator.


  • Do not put the generator inside the house, and if there is no place outside, put it in a secluded place with ventilation directly outside or on the roof inside a room that protects it from sunlight and rain. Generator smoke may cause suffocation or loss of consciousness over time.
  • Do not keep fuel close to the generator, put it far
  • Make sure that the generator set is in a dry place, away from any water source
