Why current rating in cut out is higher than the current rating of fuse in the main switch?

The current rating in a cutout is typically higher than the current rating of the fuse in the main switch to accommodate inrush currents and transient spikes that can occur when electrical equipment is powered on. Additionally, the cutout is designed to handle normal operating conditions and potential overloads without interrupting the circuit, while the fuse is intended to protect against overcurrent by breaking the circuit when a specific threshold is exceeded. This design ensures that the system operates safely and effectively under varying load conditions.
