No, due to the fact that it is both extremely dangerous and illegal. Plugging your portable generator directly into a standard wall outlet can lead to backfeeding into the utility lines connected to your house. This backfeeding can cause serious injury or even death to an unsuspecting utility worker who is working to restore power or repair downed utility lines. Additionally, connecting your portable generator to an electrical outlet poses a risk of overloading your circuits, potentially causing a fire. To avoid such disasters, it is best to have a licensed professional install a transfer switch. A transfer switch will disconnect your home from the electrical grid while allowing your generator to power your home safely. Transfer switches are available in both manual and automatic options and are recommended for use with both portable and standby generators.
