*** The first step to properly size your generator is to determine your “Power Requirements”. Please keep in mind that unless you feel qualified, you should use a certified electrician to determine your power needs. At USA Power & Light it is our goal to assist our customers in any way possible. If you have any questions, please do not hesitate to contact us.

*** Determine your need. Do you want the generator to operate part or all of your home or business?

*** Keep in mind that if you coordinate your power usage wisely you do not have to operate everything all at once. Therefore, for emergency use you don’t necessarily need to size the generator to operate everything simultaneously.

*** Please note that it is suggested, although not absolutely necessary, to size the generator 20-25% over the size you determine your needs to be. This will allow room for future growth requirements.
