How To Buy Fuses
- Examine the fuse for the manufacturer's name and part number. This information can usually be found on the body of the fuse, engraved on the metal cap or tags of the fuse, listed in a product manual or spec sheet or on the access panel or printed circuit board. You may need a magnifying glass. Jot down any information that you find.
- Take note of additional physical characteristics of the fuse. This is necessary if you are ordering online or speaking to someone on the phone to see if they carry the fuse. Note the body style of the fuse, whether the fuse is glass or ceramic and the dimensions of the fuse.
- Check the current rating of the fuse. This will be shown in amps (A) or milliamps (mA).
- Check the voltage rating of the fuse. This will be shown in volts (V) or kilovolts (kV).
- Determine the type of voltage going through the fuse. It will either be AC or DC.
