Do you want to make sure your home doesn’t lose power in the middle of the next storm or natural disaster? If so, you should purchase a generator. You can buy a portable generator that will allow you to keep your power on for a short amount of time or invest in a more permanent option that is designed to turn on automatically if your home ever loses power. A residential electrician can help you make your decision and take care of any electrical wiring in San Jose that needs to be done. Here are some tips for picking out the right generator for your home. 
Decide how much you are willing to spend on a generator before you start shopping around for one.
You can usually purchase a portable generator for as little as a few hundred dollars, but a permanent generator will typically run you a few thousand dollars. Therefore, you have to come up with a budget for your generator from the start. If you don’t have the money to spend a few thousand dollars on a generator, it’s probably not worth it to spend any time looking at permanent options. Instead, focus on portable options that will suit your needs.
Make sure the generator you choose is large enough to power your home.
When you turn your generator on, it has to be able to provide your home with all the power that it needs. Sizing a generator for your home can be very difficult, though, and it can require a lot of calculations on your part. Your best bet is to work with a company that deals with generators so that they can help you find one that’s the right size for your specific home.
Ask an electrician to install your generator for you.
If you ultimately decide that you want a permanent generator for your home, hire a residential electrician to install it for you and handle all the electrical wiring. You want to make sure that it is properly installed and that it works when your power goes out.
