💡 What prevents backfeeding when installing a manual transfer switch for generators?
A proper changeover device creates a physical gap between utility and auxiliary lines.
- You isolate the main breaker before rotating the contact blade to new voltage.
- The built interlock mechanism blocks parallel grid connection under direct current stress.
- Handy sizing matches 240 volt residential feeds without requiring commercial isolation gear.
