Generator Install questions, answered by experts

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

You can determine what size generator you need by listing the various appliances it will power during an outage. Write down the start-up watt usage, and then add them all together. 

A 7,500-watt generator will run your refrigerator, freezer, well pump, and lighting circuits without a problem. However, you’ll need an extra 3,000 to 4,500 watts to run your water heater and another 5,000 to 25,000 watts to run your electric furnace. In these instances, a whole-home generator is your best bet for running your critical equipment.

As long as your generator is used as recommended by the manufacturer, it’s safe to use for auxiliary power. Make sure that fuel powered generators are used outdoors and that the fumes dissipate away from your home. A professional generator installer will ensure your generator’s placement and set-up meets safety standards when installing or repairing your back-up power source.

No, you shouldn’t use an extension cord to plug a generator directly into your home without using a transfer switch. That’s because systems like pumps and HVAC fans need a steady power source that might not be available directly from your generator alone. If you bypass the circuit breaker box, you risk damaging your electrical system, creating a risk of electrical fire or electrical shock to you or any workers repairing lines on your local electrical grid.

You can determine what size generator you need for a transfer switch by matching the switch to the largest outlet on your generator. Larger generators can power up to 10 circuits, while most 5,000-watt generators can provide power to six circuits. So, if your generator’s largest outlet is 30 amps, you’ll need a 30-amp transfer switch.
