    I have been putting off buying a home standby generator for about 2 years now. I figured my luck was about to run out even though we have not a had a storm for a couple years I figured we are due. Sole reason I purchased this generator over others was that it was the only generator that came bundled with 150amp transfer switch and that is what my electrician wanted. It is installed now so I am ready.
