If you plan on having the generator professionally installed for you contact your installer for free advice on what to buy.

Different manufacturers have various install requirements. For example Kohler generators must be installed 5 feet from a combustible structure, while Generac requires 18” and others are different. Get information from your manufacturer with all the details
3. Noise.
While generators are very quiet they do put out 66 decibels at full load which falls between factory-noise and a classroom-setting. If you are a very light sleeper this should be taken into consideration.
4. Municipality Setbacks?
Does your city or county require generators to be set back from property lines? Contact your city or county to find out more information. One complaint from a neighbor and the generator may have to be moved and re-installed at significant expense.

8. Fuel source.
For natural gas, is my current gas meter size adequate? For propane, is my current tank large enough or what size tank should I purchase 120, 250, or even 500 gallon?
9. Spending more will guarantee better performance? Luxury car brands do not always have better gas mileage and repair records than other less expensive quality brands. There is more than one quality generator option on the market today. Look at reviews to discover which generator will represent the best value.
