Connecting Portable Generators To Home Circuits

Portable generators provide a reliable backup power source during outages or emergencies. Properly connecting a portable generator to your home circuits is crucial for safety and efficiency. This article will guide you through the process of connecting a portable generator to your home, highlighting the best options and necessary steps.

Best Option: Interlock Kit

What is an interlock kit?

An interlock kit is a device that prevents the main breaker and the generator breaker from being turned on simultaneously. It ensures that your generator and the utility power cannot feed electricity to your home at the same time, preventing backfeeding.

Advantages of using an interlock kit

Interlock kits are relatively inexpensive and easy to install compared to other options. They allow you to use your home’s main electrical panel to distribute power from the generator. Interlock kits provide flexibility in selecting which circuits to power during an outage.

Installation process

Choose the correct interlock kit, inlet box, and adapter for your main panel. Install the inlet box near the main electrical panel and connect it to the generator using a power cord. Mount the interlock kit on the main panel and connect the generator breaker to the inlet box.

Another Option: Manual Transfer Switch

What is a manual transfer switch?

A manual transfer switch is a subpanel that switches preselected breakers from utility power to generator power during an outage. It isolates the selected circuits from the main panel, ensuring safe and efficient power distribution.

Advantages of using a manual transfer switch

Manual transfer switches provide a safe and code-compliant way to connect a portable generator to your home. They eliminate the risk of overloading your generator by allowing you to preselect the circuits to be powered. Transfer switches offer a straightforward way to switch between utility power and generator power.

Installation process

Select the appropriate manual transfer switch based on your generator’s capacity and the circuits you want to power. Install the transfer switch near the main electrical panel and connect it to the selected circuits. Connect the transfer switch to the generator using a power cord and appropriate inlet box.

Tools and Materials Needed

• Safety gear (goggles, rubber gloves).
• Electric drill.
• Appropriate screws.
• Power inlet box.
• Pliers.
• Breaker interlock kit or manual transfer switch.
• Conduit and appropriate gauge wire based on generator capacity.
