a) Choose a fuse type by following the line of the AWG WIRE SIZE determined from the Wire Selection Chart

Appropriate fuses will have an amperage that intersects the AWG Wire Size line.

b) The appropriate fuse amperage will be found in one of the four gray bars below the fuse type

- Single Wire, Outside Engine Room = First column dark gray bar

- Single Wire, Inside Engine Room = First column light gray bar

- Bundled Wire, Outside Engine Room = Second column dark gray bar

- Bundled Wire, Inside Engine Room = Second column light gray bar

Example: For a 4 AWG single 105°C rated wire outside an engine room, the maximum fuse amperage is 150A.

Note:

Possible fuse amperages for a circuit can fall between a range of maximum and minimum fuse amperages. The procedure in step 1 calculates

the maximum fuse amperage which reduces nuisance blows but may offer less protection than a lower amperage fuse.

The minimum fuse amperage is calculated by multiplying the current flow in amps by 125%.

If the product instructions specify a fuse amperage, use that value if it is under the maximum amperage found in the step 1 procedure.

If the specified fuse amperage is over the maximum suggested, move down the column and choose the wire size that intersects with the specified

fuse amperage.

Calculations are based on 105°C wire. For more detailed calculations, download the Circuit Wizard app or go to
