💡 How do you pick the right three pole breaker for high current panels
Keeping your shop running smooth when wiring up new gear is pretty handy once you dial in the exact load ratings.
- Match continuous amperage to main bus capacity to prevent nuisance trips during startup surges
- Verify interrupting scores align with upstream transformer limits to keep operations safe and sound
- Select thermal magnetic styles for equipment that houses motors and heavy compressors
- Frame depth and wire termination sizes must fit your existing panel layout comfortably
