Fuse Sizing Calculator Fuse Sizing CalculatorΔThis calculator will help you determine an approximate fuse sized based on the circuit amperage when the wire size is already given or known. This calculator does not superscede manufacturers recommendations.Device Amps Wire Size – Select –16 AWG14 AWG12 AWG10 AWG8 AWG6 AWG4 AWG2 AWG1 AWG1/02/03/04/0Voltage 12Is this wire installed in an engine compartment?
