This prevents electricity from your generator from flowing outward onto city power lines and endangering people who may be working on those utilities during a power outage. It is safest and most efficient to power your house using a generator with a transfer switch that has been professionally installed.

Process of Installation
The task of connecting a transfer switch to a generator is a challenging one if it is not done correctly. To overcome this, you will only need a bit of electrical knowledge. In addition, you can finish the job within a few hours if you pay attention to detail. When dealing with the main electrical installation, it is wise to hire a electrician who is experienced in handling this type of work.
Also, be sure to comply with local and state regulations when it comes to electrical components in your home. For this to happen, it is necessary to gain insight into these laws, codes, and other general requirements. After this is done, you will be able to install the necessary equipment without violating legal requirements.
Near the main panel, you can install a manual transfer switch. During a power outage, this helps override the normal electric system with a backup generator. However, you need an operator to change the power source.
Detecting power outages and switching to backup power is easier with an automatic transfer switch. Just select a few circuits to receive the backup power. Make sure you know which loads you need to power before buying a backup generator. Usually, electricity is needed just for a few lights, and for the refrigerator or freezer. Moreover, don’t start each circuit at the same time. It may cause your generator to overload.
