Fuse Sizing Calculator

This calculator will help you determine an approximate fuse size based on the circuit amperage when the wire size is already given or known. This calculator does not supersede manufacturer recommendations.

Enter the amperage of the circuit here.

Enter the wire size used here.

Is this wire installed in an engine compartment?

If this circuit is part of a bundle of wires, how many current carrying conductors (excluding ground or communication wires) are part of this bundle?

Minimum Fuse Size 10 A
Recommended Fuse Size 15 A
Max Fuse Size 37 A

Note: The recommended fuse size is larger than the max fuse size — this wire may be too small for the amperage demands of this circuit.
