Electricity is something many don’t think about until it’s not working. For some, backup plans are already in place to ensure a continual flow of power when storms or high winds threaten to disrupt service.
The use of portable generators is commonplace during power outages, but you may not know they can potentially create one of the more dangerous situations for the linemen trying to restore power to you and your neighbors. When a generator is plugged into a wall outlet, service panel or breaker box, it produces a “backfeed,” which happens when electrical energy flows in the reverse direction from its normal flow. A backfeed reenergizes the transformer closest to your house, and puts linemen at risk of electrocution.
Think of a transformer as a funnel. As electricity enters the transformer from the powerlines, it is funneled out at a lower voltage sufficient to provide power to a household. When it enters from the reverse direction, it has the opposite effect, returning the voltage to a higher level. Linemen who are caught unaware of a backfeed could risk serious injury, or even death.
Never connect a portable generator directly to a household wall outlet. Generator power should only be connected through a properly installed transfer switch or approved interlock device that isolates the home from the utility system. This prevents backfeeding of utility lines and protects utility workers, occupants, and electrical equipment. Always follow the generator manufacturer's instructions and applicable electrical codes.
Linemen spend countless hours in dangerous situations making sure power continues to flow to every member in our service area. Help us take the necessary steps to keep them safe.
