Before installing your backup generator, follow all instructions in the manufacturer’s written documentation, such as an operating manual, and all local building codes, especially regarding placement of the unit and safe electrical connections. Not following these precautions may result in hazardous conditions, including the possibility of carbon monoxide poisoning or electrocution.
In addition, never connect a generator directly to your home’s electrical system without a proper isolation device, a switch that disconnects your house from our power lines while your generator is operating, and vice versa. This applies to both portable generators and stationary units.
To have an isolation device installed, contact a qualified electrician. Unless our lines are positively isolated from your home, operating a generator connected into your home’s wiring system could start a fire and/or electrocute a service crew member working to restore your power.
