What is a Generator Interlock Kit?
A generator interlock kit is a safety device that ensures homeowners can safely backfeed power from a portable generator into their home’s electrical system. This device prevents the dangerous situation of sending electricity back into the grid, which can electrocute utility workers or damage the generator.
How Generator Interlock Kits Work
Generator interlock kits typically consist of two sliding plates installed on the breaker panel. These plates are designed to block the main breaker while allowing the generator circuit breaker to be turned on. This mechanism ensures that only one power source can be active at a time, protecting both the home and utility workers.
Benefits of Using Generator Interlock Kits
- Safety: The primary benefit is the enhanced safety they provide, preventing backfeeding.
- Simplicity: They are easy to install and operate, making them accessible for most homeowners.
- Cost-Effective: Compared to automatic transfer switches, interlock kits are more affordable.
- Compatibility: They are compatible with most standard breaker panels, making them versatile.
