💡 What determines the right interrupt rating for commercial panel installations?
You calculate fault current capacity before picking hardware.
- Measure upstream transformer contribution to guarantee your breaker swallows the surge

- Pick a handy feed-thru model so electricians can pull wire without bending heavy conductors
- Align the voltage class with your buss bars to keep things tidy inside the box
