With proper use and maintenance, generators can provide great convenience during an outage. However, when generators are used incorrectly, they can be extremely hazardous.
Install a Transfer Switch
KEC requires that all backup generator installations have a transfer switch installed to prevent hazardous backfeed onto the utility grid in accordance with the requirements of the National Electric Code and must be approved by a state electrical inspector. For the safety of KEC employees and the public, we track where backup generators are installed on our system and require members who have installed (or plan to install) generators to contact us (this requirement includes any on-site generation, like portable generators, whole house generators, wind turbines, solar panels, etc.).
Traditional generator transfer switches are wired into the member’s electrical panel to allow power to the panel to be delivered by either the utility grid or generator, and prevent the generator from being connected to the utility grid. An alternative is GenerLink™, a transfer switch installed behind your meter. When you connect a portable cord-connected generator to GenerLink™ and start it up, GenerLink™ automatically disconnects from the electric utility grid, preventing the possibility of backfeed. This device is approved by KEC and installed by a licensed electrical contractor. Unlike some traditional transfer switches that require you to pre-select which circuits the generator will service, with GenerLink™ you have access to every circuit in your panel. You can run 120 or 240 volt appliances up to your generator and transfer switch capacity.
Dos and don’ts when using portable generators:
- DO: Install backup carbon monoxide (CO) alarms.
- DO: Keep children and pets away from portable generators at all times.
- DO: Position generators at least 25 feet outside the home, away from doors, windows and vents that can allow CO to enter the home.
- DO: Ensure your generator is properly grounded. Use a portable ground fault circuit interrupter (GFCI) to prevent electric shock injuries.
- DO: Use three-pronged extension cords that are rated to handle the load of the generator. Inspect extension cords for cuts, frays or other damage before use.
- DON’T: Operate a generator inside your home or an enclosed (or partially-enclosed) space. Generators produce high levels of CO, which can be deadly.
- DON’T: Open windows or doors while the generator is running.
- DON’T: Rely on generators as a full-time source of power. They should only be used temporarily or in emergency situations to power essential equipment or appliances.
- DON’T: Overload generators. They should only be used to power essential equipment. Make sure your generator can handle the load of the items you plan to power.
- DON’T: Connect generators directly into household wiring unless you have an appropriate transfer switch installed. If a generator is connected to a home’s wiring without a transfer switch, power can backfeed along power lines and severely injure utility lineworkers making repairs.
