What Size Generator Should I Purchase?

Once you answer that question, you can begin the process of determining which type of generator is best for your situation.

Can I Use a Portable Generator To Power Lights and Appliances In My Home?

Before I answer that question, I’ll start by saying emphatically, “Never plug your generator directly into any outlet in your home to back feed power into your house. You create a number of extremely dangerous safety hazards. You can use a portable generator to power your home provided that you have a qualified electrician install a transfer switch. If you are not qualified, never attempt to perform this installation.

Should I Install the Generator Myself?

It depends on what type of generator you are purchasing. If it is a portable generator that only requires set-up and no technically advanced installation, the answer would be, “Yes!” Provided that you understand and can follow all of the manufacturer’s instructions. For the more complicated home installations and all other commercial, business and industrial installations, we advise hiring a specialist.

I Have Medical Equipment That Requires Uninterrupted Power, What Type of Generator Should I Choose?

A permanently installed standby generator sounds like what you need. In the event of a power outage, it can automatically restore power, literally in seconds and support loads as long as needed.

Can I Use an Extension Cord With My Portable Generator?

Portable generators are designed to have appliances plugged directly into the unit. If you must use an extension cord, use one that meets or exceeds the wattage load and remember to check the cord from end-to-end for rips, cuts and frays. Finally, never use cords or generators in the rain. See, Portable Generator Safety.
