According to the provided information, a fuse box typically contains two main sets of fuses, differing in type, amperage, and application.
Types of Fuses in a Fuse Box
A standard fuse box is designed to house fuses that protect different circuits within a property. Based on the reference, these fuses are categorized by their physical design and the amount of electrical current (amperage) they handle.
Here's a breakdown of the fuses found in a fuse box:
| Fuse Type | Amperage Range | Location in Box | Description | Common Use Cases |
|---|---|---|---|---|
| Screw-in Fuses | 15-amp, 20-amp | Bottom | Screw-in with exposed glass face | Branch light circuits, outlet circuits |
| Cartridge Fuses | 30-amp, 40-amp | Top | Cartridge main fuses | Ovens, laundry rooms, stoves (higher-demand) |
Screw-in Fuses
Located at the bottom of the fuse box, these are typically 15-amp and 20-amp fuses. They have a screw-in base, similar to an old light bulb, and feature a glass face that allows you to see the fuse element inside.
- Amperage: 15-amp and 20-amp
- Physical Description: Screw-in with visible glass face
- Purpose: These fuses are specifically designed to service standard branch light circuits and outlet circuits throughout the home.
Cartridge Fuses
Found at the top of the fuse box, these are 30-amp or 40-amp fuses. They are known as cartridge main fuses and handle higher electrical loads than the screw-in type.
- Amperage: 30-amp or 40-amp
- Physical Description: Cartridge main fuses
- Purpose: These higher-amperage fuses are used for circuits that power appliances with greater power demands, such as ovens, laundry rooms, or stoves.
Understanding these two distinct types of fuses and their applications is key to identifying the correct replacement fuse if one blows in your fuse box.
