5 On Your Side: Generators and transfer switches

Whether it’s a hurricane, ice storm, even a wildfire, power outages seem to be happening more often and in more places. Maybe you’re thinking about buying a generator to keep the juice flowing. While a whole house model can be very expensive, Consumer Reports says there’s a less pricey option to power just the essentials.

Kelly Stoll and her husband had two small children when she moved to a lake community that had lost power for nearly two weeks during Hurricane Sandy. They wanted their portable generator to power their essentials during an outage.

“We have it plugged in here, the cord’s long enough, we just wheel the generator itself outside,” said Stoll.

But they didn’t want to run lots of cords through open doors. Installing a transfer switch allowed them to safely power much of their home. A transfer switch is like a mini circuit breaker panel that allows you to draw electricity from your generator instead of from the power company.

An electrician can easily install it next to your breaker panel, and you pick what circuits you want to run through it. On its own, a generator powers units that use a standard plug. But the transfer switch can power anything that’s hard-wired into the circuit panel- like a well pump, and anything requiring a 220- or 240-volt plug, like a dryer or an electric range.

Consumer Reports says to keep in mind that the generator must be at least 5,000 watts to easily connect to a transfer switch and to handle the load of several appliances.

“You want to make sure to get a generator that’s large enough to power all your essentials, but still the smallest model you canget away with because you’ll save a lot on gas,” said Paul Hope of Consumer Reports.

Plan to spend between $200-$400 for an electrician to install the switch, plus upwards of $300 for parts. You’ll lose some of the convenience of a transfer switch but save hundreds on parts using an interlock device, installed directly on your circuit panel.

“When the power goes out, you flip off the main switch with power from the street, slide this little interlock device up, and flip on this circuit breaker which allows the generator to power any of these circuits here on the main panel,” said Hope.

Consumer Reports is also reminding you that in order to avoid exposure to deadly carbon monoxide, you should never run a generator in an enclosed space. Always place the generator at least 20 feet from the house, with the exhaust pointed away from the house.
