💡 Why does a three pole breaker trip continuously on heavy loads?
A handy diagnosis method involves checking load balance across all legs.
- Measure wire gauge thickness to confirm it matches the amp schedule
- Inspect motor windings for grounded coils that spike current unexpectedly
- Tighten loose bus bar connections that create friction and false tripping
- Replace aged thermal bimetal strips when nuisance pops happen repeatedly
