### How do you calculate fuse wire size?

To calculate a fuse rating, manufacturers work from a simple equation:

- Power (watts) = Voltage x Current (amps) What we really want to know with this equation is the current (amps).
- Amps = Watts / Voltage. So, let’s say we need to work out the fuse rating for a washing machine.
- 850/120 = 7.08 amps.

### How do I choose a fuse wire?

Always select a fuse size to protect the wire according to its rating. In some cases, a product manufacturer will specify a fuse value and it will usually be lower than that required for protecting the wire. If this fuse value is too high to protect the wire, use a bigger wire in the circuit.

**What size fuse do I need for my amp?**

If your amplifier has an internal fuse, your inline car amp fuse should be a bit larger. For example, use a 25- or 30-amp inline fuse if your amp has an internal 20-amp fuse. If you have two amps with internal fuses, add the amperage ratings together to figure out the right size for your inline fuse.
