"Cale and his team have done a couple big jobs for us - installed a generator hookup/transfer switch and upgraded our system from 100 to 200 AMPs. Of all contractors I've worked with, Paradise Electric is by far the best, most-efficient, tidy, responsive, reliable, high-value operation I've dealt with. I am very thankful to have found this team and highly recommend them for any electrical work."

"I have found my forever electricians (at least while I live in the New Haven area)! From start to finish my experience with Power Forward was an absolute pleasure. Company owner, Ian, was responsive, punctual, and incredibly informative when it came to walking me through the details of the scope of work I was requesting, and was thoroughly transparent and fairly priced when it came to his estimate. Once we accepted the quote, scheduling with Morgan was easy and efficient, and Chris arrived onsite within a day of me accepting the estimate. Chris was a consummate professional, a super clean worker when it came to caring for our house and the cleanliness of his cable paths, and was truly dedicated to doing the job â the right wayâ not just the easy and cheap way. He took his time and planned his cable runs and circuiting carefully to ensure both minimal cutting into our walls and convenient receptacle placement. Once he was finished, he took care to clean every area heâ d worked in and probably left some of the rooms cleaner than when he arrived! I would recommend Ian and Power Forward to anyone who appreciates work that is done with care, safe, and efficient. I think you get what you pay for when it comes to hiring trade professionals, and electricity is not something you want to cut corners with: hire Ian and his team, and have it done right and safe the first time."

Generator Install questions, answered by experts

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.

Sizing a generator is a careful process that requires calculating the electrical load of your entire house. You have to take into account every device you want to use and their wattage requirements, plus the wattage needed to start them, and look for a generator that can safely run all that at around 80% capacity.

In more practical terms, a small home can run on a 10,000-watt generator (and if you only want to power a few key appliances, much less than that). A mid-sized home may need something between 15,000 and 22,000 watts. Larger homes require 25,000 watts or more. 

A home that is 2,500 square feet will likely need a 20kW to 25kW generator. Consult your local generator installer to confirm the generator size needed to power your home before purchasing a new one. Be sure to consider how much power your necessary devices need to run.

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. 

Carbon monoxide emissions aren’t only dangerous to human life, but they also harm our planet. While natural gas generators emit lower levels of CO than other fuel sources, there are still ways to reduce emission levels. For example, shop around for an eco-friendly generator that complies with current emission standards. Also, make sure your generator is serviced regularly to avoid CO buildup.
