"Mike re-wired my basement outlets at my apartment. He figured out that all of them were wired incorrectly. Not only did he restore power to my basement outlets, he prevented an electrical fire from the previous incorrect wiring. He also installed a new bathroom fan/light combo, with Bluetooth speaker capabilities and multiple led light colors. He was efficient, fairly priced and honest. Highly recommend! Thank you again Mike!"

"Lenny and his team at Limitless Electric were outstanding, professional, on time, and incredibly reliable. He resolved my solar accounting issues, added outlets, ran a Cat6 drop, and updated my Powerwall system for full-house backup. I really appreciate their clear communication and dependability, especially after dealing with other contractors who were constantly late despite doing good work. Limitless Electric is now my go-to for all future electrical projects—highly recommended!"

"Philip has excellent customer service. He was quick and efficient in installing the ecobee 4 for us. He even took the time to recommend a viable alternative to the other thermostats we would need without adding additional wiring. We will definitely be hiring him again for future electrical work. Thanks Philip!"

"My garage electricity was out. I called him to get an estimate. He gave me a couple of troubleshooting suggestions for free. I followed them and they worked. Now, how can you not hire him if you had work to be performed or better yet, I thought of some things to be done around the house just to hire him for his honesty. People like him are rare to come by these days."

"Very professional and timely. He was really good at identifying any problems and suggesting fixes for them. Also very patient with all my questions and explaining the process. He installed a bathroom vent fan, a recessed light in the bathroom, and lights over my bathroom vanity. He also ran wires from the panel box to one of my bedrooms and installed more outlets as the room only had one. Helped me get an outlet for a garbage disposal and microwave over my stove. All done within a couple days as we completed other work."

FAQs for electrical wiring or panel upgrade projects in Simsbury, CT

A whole-house surge protector blocks voltage spikes from lightning, grid issues, or even large appliances before they can fry your wiring or electronics. By diverting excess current at the main panel, it shields everything from your HVAC to your phone chargers and can extend the life of pricey appliances. Homeowners in storm-prone regions or with older panels see the biggest payoff, but any home that relies on sensitive electronics benefits.

Most whole-house surge protectors work for two to three years. Low-level spikes—too small to notice—hit your panel every day and slowly wear down the internal components. Once the unit’s capacity is depleted, it can’t prevent a larger surge, so plan to replace it on schedule (or sooner if a major lightning strike occurs) to keep your electronics and HVAC equipment safe.

A surge protector begins guarding your circuits the moment an electrician snaps it into place. Whether the spike originates from a nearby lightning strike or your fridge kicking on, the protector shunts the extra current to ground before it can reach outlets or hard-wired systems, such as your AC. That instant response is why a small upfront cost can save thousands in appliance repairs.

The unit mounts on or next to your main electrical panel. Type 1 models sit on the supply side, catching outside spikes before they hit the breaker. Type 2 devices snap inside the panel and tame surges that start within the house. Either way, placement at the panel lets the protector guard every circuit at once.

Plan to swap the device every three to five years—or sooner if you upgrade your panel, add high-demand appliances, or notice flickering lights and tripped breakers. Relying on a maze of power strips is another red flag that your current setup isn’t keeping up. Replacing the surge protector at these milestones keeps your electrical system on safe footing.
