How Does an Interlock Kit Prevent Backfeeding and Protect Utility Lines?
An interlock kit uses a mechanical barrier to prevent you from switching on both the utility and generator breakers at the same time. This design guarantees the utility lines can’t backfeed into your home or the grid, protecting lineworkers and your neighbors. By physically blocking one breaker when the other is engaged, the system maintains safe, isolated power sources.
