"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

While the rating will tell you how many watts the refrigerator needs at the peak of its cycle, it requires additional wattage to start. At the bare minimum, you’ll need a 1,500-watt generator to get the fridge up and running after a blackout. A 2,000-watt generator should be sufficient for most home refrigerators.

Generators run on a variety of fuel types, ranging from natural gas to solar power. Keep in mind that fuel costs varying by type:

  • Natural gas: $2,000–$21,000 per year 

  • Liquid propane: $2,000–$21,000 per year

  • Diesel: $3,000–$20,000 per year

  • Gasoline: $500–$3,000 per year

  • Solar generator: $2,000–$25,000 per unit

  • Battery backup: $10,000–$25,000 per unit

Homeowners can often access federal tax credits, such as the Investment Tax Credit (ITC), which covers a percentage of installation costs. Many states and utilities offer additional rebates, grants, or performance-based incentives. These programs can significantly lower your upfront investment. Check the Database of State Incentives for Renewables and Efficiency (DSIRE) or contact your local energy office for current offers.

As a safety measure, you should always turn off the main breaker while operating your generator’s backup breaker. In addition, you should also switch off all appliance breakers so you don't have a power surge when the main breaker turns back on. And finally, turning off the main breaker prevents back-feeding, which endangers utility workers with the risk of electrocution. Back-feeding could also destroy the electrical circuits of your neighbors if they use the same power network.

Portable generators provide backup power for essential appliances during outages and are easy to relocate.
