"Glen and his team were prompt and professional during both installation and annual maintenance. We lost power during the last hurricane and the generator worked perfectly. Pricing was very good and Glen was even able to get me an extended warranty (promo from Generac). I would recommend Green Sun."

"I cannot recommend RYB Electric LLC and Sebastian highly enough! We hired them for several electrical upgrades, including: 1. A full electrical panel upgrade 2, Installation of a Level 2 EV charger, and 3. Installation of ground rods for extra protection Beyond his technical expertise, Sebastian is a pleasure to work with. He is incredibly easy to talk to, has a great personality, and took the time to answer all my questions without making things feel overly complicated. It’s rare to find someone who is both a master of their craft and so personable. The workmanship is top-tier—everything is neatly installed, labeled, and functioning perfectly. If you are looking for a reliable, skilled, and fairly priced electrician who truly cares about the quality of his work, look no further than Sebastian. We couldn't be happier!"

"Roy is really a prof. He installed two overhead fans and a hanging lamp. The fans had a complicated control system but he was able to get them to work flawlessly. Bonus: he is really a nice person and he cleaned up too! I would recommend his work to anyone."

"Chris called me back the day I called him. Once my lighting fixture arrived he showed up the next day and installed it. Rate was reasonable compared to other companies. I would use this company again and I would highly recommend them."

"Hank's Electrical is a quality company. I have used him at least 4-5 times within the past 1-2 years and he never disappoints. He has done a number of jobs at my house including outlet installation, landscape lighting and generator installation. Extremely responsive and aims to please. He takes pride in his work and is very efficient, tidy and will give you a fair and honest estimate. Would feel very comfortable referring him to family and friends who need any electrical work."

"We called PipeWorks for an emergency hot water heater replacement on a weekend. In approximately one hour, they had a technician, Pablo, at our house to assess the issue. Pablo was extremely professional and made safety during the COVID pandemic a top priority as he did his work. He was able to get us a replacement water heater and install it the same day and completed the job within a few hours of when he first arrived. He answered all of our questions, did a terrific job, and even called us later that evening when we had reached out through the main number with a follow-up question. We were so grateful for Pablo's expertise and professionalism."

Generator Install questions, answered by experts

Here’s what you can run with different wattages and types of generators:

Portable generator:

  • 2,000 watts can handle a large appliance like a freezer or refrigerator, plus a few smaller items like phones or computer chargers. 

  • 4,000 watts will keep two large appliances operating and a few smaller devices.

  • 8,000 watts should power most essential appliances and other devices, including a sump pump, well pump, or your dishwasher.

Partial to whole-house generator:

  • 20,000 watts and above will make it seem like your home’s power is still on.

Generally, you’ll want to keep between 60 and 70 feet between the generator and the transfer switch. There are a few reasons for this, including:

  • The distance reduces the noise coming from the generator into your home.

  • It increases efficiency because you won’t have a voltage drop from this short of a distance.

  • Prevents carbon monoxide poisoning: keep at least 15 feet between your generator and an open window. 

In many cases, yes. There are models called dual-fuel generators and fuel switches, but only between certain types of fuel. For example, with the right setup you can convert a generator from natural gas to propane. Some allow switching between diesel and gasoline. There are even tri-fuel generators available in some cases, which adds a large layer of security if you are worried about fuel availability in times of crisis. Always check your generator capabilities and manual instructions before trying to switch fuels. Some generators can use another fuel but may need a fuel conversion kit to prep them first.

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.

If your home already has a grinder pump and you’re still noticing issues (like frequently clogged toilets and sinks), it could be time to upgrade your grinder pump. Start by checking your existing horsepower. If there are four or fewer people living in your home, using a 1/2-horsepower grinder pump should be sufficient. Larger households should consider investing in a 1-horsepower grinder pump to maximize wastewater removal efforts.
