Be Ready Before the Power Goes Out.
Professional portable generator electrical connections and interlock systems designed around your panel, generator and backup-power priorities.
A portable generator should connect to your home safely and intentionally.
Running extension cords through the house is not the only way to use a portable generator. A properly planned generator inlet and compatible panel interlock can make it easier to supply selected circuits while keeping the electrical system configured correctly.
A.T. Electric evaluates the panel, generator capacity, desired backup loads and applicable electrical requirements before recommending the connection method.

Generator hookup FAQs
What is a generator interlock?
It is a compatible mechanical device that prevents the generator breaker and main utility breaker from being on at the same time.
Can I power my whole house with a portable generator?
That depends on generator capacity and household loads. Many homeowners prioritize selected circuits rather than every load.
Do I need a generator inlet?
A dedicated inlet is commonly used to create a cleaner connection between a portable generator and the home’s electrical system.
Do generator hookups require permits?
Requirements vary by jurisdiction and scope. We address applicable permitting requirements when planning the installation.
