Generators FAQ

Buying a generator, though a very good move for safety and piece of mind, can be confusing with all of the options. Here are a few of the most frequently asked questions to help you find the right model for your needs.

Generators FAQ
Your backup power questions, answered

Q: What type of fuel should I choose for my standby generator?

A: Standby generators sit for long periods of inactivity and letting gasoline or diesel sit and gum up the inner workings of the engine could negate everything you need a generator for.

This makes liquid propane the ideal fuel for standby generators. The lower cost of installation and maintenance, along with the ability to buy larger storage cylinders leaves the competition in the dust.

Also, for a more bountiful supply of fuel, it is a rather easy procedure to connect the generator to your home's natural gas line.

Q: What type of fuel is best for a portable generator?

A: Since portable generators are typically used more often than the standby variety, diesel fuel is the better way to go.

Diesel fuel has a shorter shelf life and engines are a little more expensive than gasoline or propane, but the lower fuel cost makes it the most financially efficient generator.

Also, diesel has a better performance per volume ratio, often exceeding propane by 30 to 40 percent!

Q: Can I use a portable generator to power my house like a standby generator?

A: If a portable electric generator is deemed the right style for your emergencies, be sure to install the right power transfer switch to allow a manual changeover.

A power transfer switch is installed beside the main electrical panel, and then it's connected to the circuits you'll want running during a blackout. When the power goes out, you simply crank up the generator and run a single power cord from it to a transfer switch.

Q: How do I know what size generator to buy?

A: Be sure to choose a generator that can put out enough power for your plug-in appliances. For basic emergency use, 2,500 to 5,000 watts should be sufficient. It is a good idea, however, to add up the approximated power draw of what you want powered and move from there.

Obviously, the more items that need power, the more wattage you're likely to need.

For a standby generator, your normal power draw may require a larger generator than you're willing to buy. In this case, consider a dedicated circuit generator, which only powers the circuits you choose.

This way, only mission essential appliances like the refrigerator, sump pump and furnace/ air conditioner can be powered without juicing up every outlet.

Q: How can I be sure my standby generator will transfer power?

A: Since standby generators are "rainy day" appliances, they will see a lot of down time. It's best to give them regular maintenance every 9-18 months to ensure there are in the best working order.
