There are two simple ways available for you, which can help you to power appliances:

  • You can connect your generator to the house electricity board.
  • You can connect appliances to the generator.

If we talk about first option, so you can connect your appliances through extension cord to your generator its is the best option but when there would be extended power outage you don't have nay option left to connect home appliances with generator.


When we talk about second option where you can connect your generator to the home appliances, and you are going to run all the appliances normally as you run with the electricity power until the generator has power left. So this is also a better option and now it's up to you which one you are going to use.

You also have to take care plugging a generator to the wall socket directly because it can damage your electricity, appliances or even can burn your wires so beware of this. 

It can not only harm you, also can harm the technician who is working on electric lines, that's why it is an illegal thing.

There is a transfer switch tool available which helps you to connect your generator to your home.

You have to install it in electricity circuit breaker box because it is device which uses for electric control and the other work of transfer switch is to switch your home electricity on to the generator.

We can say transfer switch makes power management easy and it is work like your home circuit you can run whatever you want to run appliances or home. While installing transfer switch it is in your control which outlet on which sub beaker.

In the market there are two types of transfer switches available:

  • Manual transfer switches
  • Universal transfer switches  

Manual transfer switches work like people are using for long time (traditional) circuit breaker box and with this very simple to flip the breaker just turn on or off one set off appliances.

If we talk about universal transfer switch so, it works automate you don't need to do anything again and again once you have decided your priority outlets transfer switch automatically on and off the breakers and will provide the power below the generator's starting watts.

When the utility grid’s power fails universal transfer switch detect it and works automatically and switch over to the generator. 

There are some transfer switches comes with battery back up which saves your appliances and keep running them until you turn on the generator. And when the power comes back universal transfer switch automatically switch your home back on to electric grid, so you don't need to worry it works automatically.

When you are installing a transfer switch the main thing you have to consider is which circuit from your main circuit board is going to be connected with transfer switch circuit.


It is also depended on you that which appliances you are going to run and the size of your generator and if you are using universal transfer switch then you can prioritize your important appliances.

Connecting Generator
