RV Fuse Box Basics

An RV fuse box is a central location where all of the electrical circuits in your RV are protected by fuses. When a fuse blows, it interrupts the flow of electricity to that circuit, preventing damage to your RV’s electrical system.

RV fuse boxes are typically located in a central location in your RV, such as under the dashboard or in a compartment near the entry door. They are typically made of metal and have a clear cover so that you can see the fuses inside.

Each fuse in an RV fuse box is responsible for protecting a specific circuit. The amperage rating of a fuse indicates the maximum amount of current that it can safely carry. If the current flowing through a fuse exceeds its amperage rating, the fuse will blow.

RV fuse boxes typically contain a variety of different types of fuses, including:

  • ATO fuses
  • ATC fuses
  • Blade fuses
  • Miniature fuses

The type of fuse that you need will depend on the amperage rating and the size of the fuse holder.

Types of RV Fuses

RV fuses come in a variety of different types, including:

  • ATO fuses
  • ATC fuses
  • Blade fuses
  • Miniature fuses

The type of fuse that you need will depend on the amperage rating and the size of the fuse holder.

ATO Fuses

ATO fuses are the most common type of fuse used in RVs. They are cylindrical in shape and have a metal cap at one end. The amperage rating of an ATO fuse is printed on the metal cap.

ATO fuses are available in a variety of amperage ratings, from 1 amp to 30 amps. They are typically used to protect circuits that draw a small amount of current, such as lights, fans, and small appliances.

ATC Fuses

ATC fuses are similar to ATO fuses, but they have a built-in thermal sensor. This sensor helps to prevent the fuse from blowing if there is a sudden surge in current.

ATC fuses are typically used to protect circuits that draw a large amount of current, such as air conditioners, refrigerators, and microwaves.

Blade Fuses

Blade fuses are flat, rectangular in shape, and have two metal prongs on one end. The amperage rating of a blade fuse is printed on the body of the fuse.

Blade fuses are typically used in older RVs. They are available in a variety of amperage ratings, from 1 amp to 30 amps.

Miniature Fuses

Miniature fuses are small, round in shape, and have two metal prongs on one end. The amperage rating of a miniature fuse is printed on the body of the fuse.

Miniature fuses are typically used in newer RVs. They are available in a variety of amperage ratings, from 1 amp to 30 amps.

II. How to Find Your RV Fuse Box

Your RV fuse box is typically located in a central location, such as under the dashboard or in a compartment near the entry door. It is a metal box with a clear cover that allows you to see the fuses inside. The fuses are typically color-coded, so you can easily identify which one goes to which circuit.

If you are having trouble finding your RV fuse box, consult your owner’s manual. It will provide you with the exact location of the fuse box, as well as instructions on how to read and replace the fuses.

IV. Types of RV Fuses

There are two main types of fuses used in RVs: blade fuses and ATC fuses.

Blade fuses are the most common type of fuse found in RVs. They are small, rectangular pieces of metal with a metal strip running through the middle. The metal strip is what melts when the fuse blows, which prevents the flow of electricity and protects the RV’s electrical system.

ATC fuses are a newer type of fuse that is becoming more common in RVs. They are larger than blade fuses and have a plastic housing with a metal cap. The metal cap contains a small metal button that melts when the fuse blows. ATC fuses are more expensive than blade fuses, but they are also more reliable and easier to replace.

The type of fuse used in an RV will depend on the size of the RV’s electrical system. Smaller RVs typically use blade fuses, while larger RVs may use ATC fuses.

Here is a table that summarizes the different types of RV fuses:

Type of Fuse Size Maximum Amperage
Blade Fuse 5 mm x 20 mm 15 amps
ATC Fuse 10 mm x 32 mm 30 amps

IV. Types of RV Fuses

There are two main types of fuses used in RVs: blade fuses and mini-blade fuses. Blade fuses are the traditional type of fuse, and they are typically used in older RVs. Mini-blade fuses are a newer type of fuse, and they are typically used in newer RVs.

Blade fuses are identified by their color and amperage rating. The color of the fuse indicates the type of circuit it protects, and the amperage rating indicates the maximum amount of current that the fuse can handle. Mini-blade fuses are identified by their size and amperage rating. The size of the fuse indicates the type of circuit it protects, and the amperage rating indicates the maximum amount of current that the fuse can handle.

Here is a table that lists the different types of fuses used in RVs:

Fuse Type Color Amperage Rating Circuit Protected
Blade Fuse Blue 15 amps 12-volt DC circuits
Blade Fuse Red 20 amps 12-volt DC circuits
Blade Fuse Yellow 30 amps 12-volt DC circuits
Blade Fuse Green 40 amps 12-volt DC circuits
Mini-blade Fuse Blue 5 amps 12-volt DC circuits
Mini-blade Fuse Red 10 amps 12-volt DC circuits
Mini-blade Fuse Yellow 15 amps 12-volt DC circuits
Mini-blade Fuse Green 20 amps 12-volt DC circuits

V. How to Replace an RV Fuse

To replace an RV fuse, follow these steps:

  1. Locate the fuse box. The fuse box is usually located in a central location in the RV, such as under the dashboard or in a closet.
  2. Turn off the power to the circuit that you are working on. This will prevent you from getting shocked.
  3. Remove the old fuse by carefully pulling it out of the fuse holder.
  4. Match the new fuse to the old fuse by checking the amperage rating and the type of fuse.
  5. Insert the new fuse into the fuse holder.
  6. Turn on the power to the circuit.

Once you have replaced the fuse, test the circuit to make sure that it is working properly.

IV. Types of RV Fuses

There are three main types of fuses used in RVs: blade fuses, mini-blade fuses, and ATC fuses.

Blade fuses are the most common type of fuse used in RVs. They are typically round or square in shape and have a metal blade on each side. Blade fuses are rated in amps, which indicates the maximum amount of current that the fuse can safely carry.

Mini-blade fuses are smaller than blade fuses and have a single metal blade. Mini-blade fuses are also rated in amps.

ATC fuses are the most advanced type of fuse used in RVs. They are self-resetting, which means that they can be reset after they have blown. ATC fuses are also rated in amps.

The type of fuse that is used in an RV depends on the size of the circuit. Blade fuses are typically used for larger circuits, while mini-blade fuses and ATC fuses are typically used for smaller circuits.

VII. Common RV Fuse Problems
