We can't emphasize enough the danger associated with connecting a portable generator directly to your home's electrical system via one of the existing receptacles, like your dryer plug. This is called backfeeding, and during an outage it can send electricity back over utility power lines and injure or kill utility workers. Additionally, when utility power does return, it can damage your generator and your home's electrical system, and even cause a fire.
You can, however, safely connect a portable generator to your home's electrical supply with a manual transfer switch. A manual transfer switch acts as an interface between the generator and your home's electrical supply. Generac does not manufacture manual transfer switches, but an electrician or authorized Generac dealer (http://goo.gl/fDlS1
) can recommend one for you. To work properly, you will need a three-pole transfer switch. Additionally, because Generac portable generators are bonded neutral while most transfer switches are floating neutral, you will need a transfer switch that also switches the neutrals.
