How do I choose the right fuse size for my DC circuit based on the current rating and load requireme

Choosing the appropriate fuse size for a DC circuit is essential for ensuring the safety and reliability of the electrical system. The correct fuse size is determined by the current rating of the circuit and the load requirements. Here's a guide on how to select the right fuse size:

1. Determine the Load Current: The first step is to calculate the maximum current that the circuit will carry under normal operating conditions. This can be found on the nameplate of the device or by using the formula:
