Portable generators are a practical backup power solution, but connecting them safely to your home’s electrical system requires a licensed electrician. Running a portable generator with extension cords is inefficient and potentially dangerous. Back-feeding power into utility lines without proper protection can be fatal to utility workers. A generator interlock kit and power inlet box is the safe, code-compliant solution, and Miele Electric Power installs them across Connecticut.

How a Generator Interlock Kit Works

A generator interlock kit is a mechanical device installed directly on your electrical panel that physically prevents the main utility breaker and the generator breaker from being on at the same time. This eliminates the risk of back-feeding power into the utility grid, protecting both your equipment and utility workers. Paired with a power inlet box installed on the exterior of your home, an interlock kit allows you to connect your portable generator to your home’s wiring using a heavy-duty generator cord. Once connected, you can selectively power circuits in your panel by switching on individual breakers (lights, refrigerator, furnace blower, sump pump) up to the capacity of your portable generator. Miele Electric Power installs interlock kits that are compatible with your existing panel brand and model, pulls the required Connecticut permit, and completes the installation to NEC code standards. A proper permit and inspection protects your homeowner’s insurance coverage and ensures the work is done correctly.

We assess your existing electrical panel to confirm interlock kit compatibility, determine the right inlet box location, and provide a clear written quote for the installation.

Frequently Asked Questions

Is an interlock kit as good as an automatic transfer switch?

An interlock kit is a safe, code-compliant, and more affordable alternative to an automatic transfer switch for portable generator users. The key difference is that an interlock kit requires manual connection of your portable generator, while an automatic transfer switch (used with standby generators) operates automatically the moment the power goes out. If you want true automatic backup power, a Generac standby generator with an automatic transfer switch is the better long-term solution.

Can I install a generator interlock kit myself in Connecticut?

No. Generator interlock kit installation requires a licensed electrician and an electrical permit in Connecticut. Unpermitted work can void your homeowner’s insurance and create serious safety hazards. Miele Electric Power handles the full installation and permitting process.

What size generator do I need for an interlock kit installation?

The generator size you need depends on which circuits you want to power during an outage. A 5,000-7,500 watt portable generator can typically power essential circuits including lights, refrigerator, and a well pump. For central air conditioning or electric heating, you’ll need a larger unit. Miele Electric Power can help you assess your needs during your free quote.

 Trustindex verifies that the original source of the review is Google. I could not be happier with my experience with Miele Electric Power.  From my first conversation with Carl on the phone, I knew that he knew what he was talking about, and there was no high-pressure salesmanship.  He took charge of the project of installing my whole-house generator and maintained contact throughout the process.  His workers were equally professional.  I would recommend Miele Electric Power without qualifications.

 Trustindex verifies that the original source of the review is Google. The process for getting a generator estimate and its installation was very efficient with Carl Miele and the Miele Electric crew. Carl took the time to explain what our house would need without overselling us (which happened with other electricians). The work was completed efficiently from the installation of generator to the propane tanks to the building inspector’s approval. We are very happy to have chosen Miele electric. We recommend their services and Carl will be our electrician moving forward. We thank his company for their professionalism and expertise.

 Trustindex verifies that the original source of the review is Google. So far so good, but with an emergency generator, rubber meets the road when and if there is an issue and the response. However, everything Carl (owner) said he would do on installation and follow through went down just as he said it would. His people could not be nicer to deal with. What made me go with Miele Electric was the number of techs he has on staff. Other companies I priced out and had conversations with had 1-2 tech guys available which is huge when there could be an issue with my generator during a power outage.
Lastly, Miele was the only company of the 4 I entertained that the owner personally was involved from the get go. No leaving messages, getting put to an answering service, having to schedule the initial call weeks in advance, ect. Carl gave me his cell and had a written quote to me next day. As a business owner myself, that is a huge positive.
