"I recently had the pleasure of working with Champ Electrical, and I was thoroughly impressed with their professionalism, efficiency, and quality of work. From the initial consultation to the final installation, their team demonstrated excellent communication and technical expertise. What stood out most was their attention to detail and commitment to safety. They explained every step of the process clearly and ensured that all work was compliant with the latest electrical codes. Whether it was troubleshooting an existing issue or installing new wiring, their electricians were knowledgeable, courteous, and respectful of our property. Pricing was transparent and fair, with no hidden costs. Scheduling was also smooth—they arrived on time and completed the job within the estimated timeframe. If you're looking for a reliable and trustworthy electrical company, I highly recommend Champ Electrical. They truly live up to their name, delivering championship-level service every time."

"Punctual and professional. All of the work was completed right on schedule. They upgraded my entire home and replaced electrical panel. Definitely hiring again; I have them scheduled to repair the sprinkler system electrical work and the fans in both my bathrooms. The cost was surprisingly affordable! I cannot recommend enough."

"If I could give this company an A+++ I would. From the beginning, the entire job was explained over the phone, very detailed and 100% transparent. No surprises. The work was scheduled immediately an ended up being completed 3 weeks ahead of schedule- which is key when you're entering winter and you need a generator for blackouts in stormy weather. The installers showed up on time on every single occasion. They were quick, reliable, NICE, clean, and steadfast. The management kept me informed by telephone each time they were coming by my property and explained exactly what they were completing that day. The entire job was completed in roughly 8 days including permits. I have also contacted Cape Cod Independent Power post install and they respond 100% of the time in an extremely quick manor. I've been dealing with contractors for over 20 years and this team is one of the best I have ever dealt with. A true pleasure to work with."

"He was on-time, but was frustrated that there was no parking due to all the snow.  He was going to cancel, but we were able to find him a spot.  Initially he seemed a little annoyed with the circumstances, but ended up being really nice and helpful.  He had never installed a microwave before, so he was going through the directions along with me, but we got it up.  He patched up a hole we had, then a few shelves.  We ended up getting along really well, and he was kind enough to split his time within two visits, since we didn't have one of the items that we initially thought we would have. 
Overall it was a really good experience.  It was a rocky start, but after we got over the parking situation, he was professional, and really helpful with everything we needed from his end.
We were very happy with their service, thank you!

Generator Install questions, answered by experts

Generators are safe to use as long as they are installed and operated correctly according to the manufacturer's recommendations. The most critical safety tips are to never use a portable or fuel-powered generator inside an enclosed space due to the risk of lethal carbon monoxide poisoning; always operate it outdoors where fumes can dissipate away from your home. Additionally, never attempt to connect a generator to your home’s electrical panel yourself—hire a professional to ensure the setup meets safety standards. Finally, avoid overloading the generator by not connecting more appliances than it is rated for, as this can damage your equipment or cause a fire.

While natural gas generators are costly, they’re a great option for standby power due to the reliability of natural gas as a fuel source. Unlike other fuels, natural gas is delivered through underground pipes, making outages extremely rare and less likely to be affected by the elements. As long as the area isn’t prone to earthquakes, they offer an unlimited supply of natural gas that doesn’t degrade over time or require storage in tanks.

A 1,500 square foot home will likely need a 15kW to 20kW generator. When deciding on whole-house generator size, add up the total wattage of the devices that you’d like to continue running during a power outage. That way, you can ensure you purchase a generator that can power your necessary appliances or medical equipment during an electrical emergency.

You can expect a diesel generator to last for up to 30,000 hours of use, which works out to 20 to 25 years with the proper maintenance, of course. That depends on how much you use it, so a diesel generator used for emergencies a couple of times a year will last a lot longer than a generator that takes over for a faulty electrical grid every month for a day or two. 

It is safe to run a generator continuously, but you must follow safety protocols to ensure personal and home safety. Read the manufacturer’s instructions for specific recommendations, but the general recommendation is to turn generators off overnight or when you’re away from the house. Overworked generators can pose a fire hazard and if your generator is not in a well-ventilated area, running it continuously could lead to carbon monoxide poisoning.
