BreakerSizingPro

BreakerSizingPro is a useful app to help you calculate the correct circuit breaker size for different electrical needs. It can determine breaker size based on load current, motor loads, and whether the load is continuous or not. The app also considers factors like temperature derating and voltage drop.

It includes tools for calculating short-circuit interrupting capacity and inrush current. You can size breakers for multi-wire circuits and check coordination with upstream devices. BreakerSizingPro also supports arc fault protection sizing.

This app is great for electricians, engineers, and anyone working with electrical systems.
