In this blog post, we will answer the question: “What size breaker do I need for a 30 amp RV plug?” We will talk about the 30 amp RV plug requirements along with the number of outlets that can be used. We will also discuss how to reset, test, and replace a circuit breaker with a few tips listed.
What size breaker do I need for a 30 amp RV plug?
You will need a 30 amp breaker to use with a 30 amp RV plug. 30-amp breakers are well suited for a 30-amp RV plug. You can also use a 15 or 20-amp breaker if you do not have a 30-amp RV plug. However, it is not recommended to use a 15 or 20-amp breaker since you run the risk of damaging your RV. A 30 amp breaker is not too expensive and you can get one with ease.
A 30 amp RV plug consists of three prongs. There is a ground wire, a neutral wire, and a 120-volt hot wire. The 30 amp RV plug is most used in RVs that have a low electric load. The 50 amp RV plugs are different from the 30 amp ones. It is also advised to upgrade from a 30 amp RV plug to a 50 amp RV plug.
30 amp RV plug and requirements
- A 30 amp RV plug will need around 3,600 watts to run successfully.
- You will need to calculate how many watts are needed to successfully run a 30 amp RV plug. The basic formula is 30 amp into 120 Volts.
- If you are planning on connecting an RV to a house, you will require a 15 A male adapter that is connected through a 30 A female adapter.
- Commonly known as RV-30, these 30 amp RV plugs are very common and can cost you from $150 to $200.
- Installing a breaker is not too hard and you might be able to do it on your own. Be sure to note that these 30 amps can only have a 10 gauge wire.
- You are not advised to run a 12 gauge wire for a 30 amp circuit. This is because 12 gauge wires are not suited for handling more than 20 amps.
- It also depends on the distance, the 10 gauge wires are used for a short distance. You will need an 8-gauge wire if you are planning on running the wire for more than 150 feet.
- Always remember that a 10 gauge wire is not meant for long distances, the only other best option would be a thicker 8 gauge wire.
Number of outlets on a 30 amp breaker
Many people have always wondered how many outlets can be on a 30 amp breaker. This depends on the type of appliances or machines you are planning on using. It is not recommended to use more than two outlets on a 30 amp breaker. This is because 30 amp breakers are used only for heavy-duty appliances like heating systems and HVACs.
In case of connecting your rig, it is advised to have only one outlet on a 30 amp breaker. There are a few multi-outlet breakers, but these breakers are cut short to 20 amp circuits. Another option is to use a 20-amp and 15-amp receptacles on the 30-amp circuit. That said, be sure you know what you are doing before trying to connect your RV.
When you are looking at the outlets at home, this can be different. You will be able to find a combination of outlets that are used. There are 15 and 20 amp breakers for appliances at home. On the other hand, 30 amp breakers might be used for heating systems or air conditioners. For an RV, you will need to get the right 30 amp breakers to take the load.
Double pole 30 amp breakers
Be sure to stick to the usual and do not try to experiment without knowing what you are doing. Many people think that they can use a 30-amp breaker with two hot wires. This is not recommended and it can cause serious damage and danger. Be sure to use a single-pole breaker with one neutral, one hot, and one ground wire.
How to reset tripped breakers?
RV breakers often trip based on the usage and appliances that you connect. It is common for an RV breaker to trip, especially when you have a hot summer night and plan on running the air conditioner for a long time. While it is always good to hire a professional to get this job done, it is always good to know it on your own. This can come in handy when you are camping in remote areas.
- When you have a tripped breaker, the first thing you will need to do is locate the breaker panel.
- The latest RVs have their breaker panel located with the low-voltage fuse panel. This can be found attached to the power converter.
- Once you located the breaker panel, you will be able to identify which switch has been tripped.
- The biggest mistake everyone makes is by turning the switch back on. This is not advised since there are chances of the breaker tripping again.
- Before resetting the breaker, be sure to unplug or turn off any heavy equipment that has been running.
- In most cases, the breaker will trip due to air conditions or appliances that consume high electricity.
- Once you unplug or switch off some of the heavy electrical appliances, you will be required to turn on the switch.
- Note that you might need to flip the switch back to the off position if they seem to be tight. Push the switch back and they bring it on again.
- If the breaker continues to trip, then there might be some issues with the wiring.
Testing the circuit breaker
This is a known fact that breakers can wear out after one point in time. If a breaker has tripped several times in the past, there is a high possibility for it to wear out soon. You will get to know this since a breaker will simply not take the required load. Be sure to call a professional in this case if you are not comfortable working with circuit breakers.
- Touching the wrong wire can be dangerous so ensure that there is no power passing through.
- You will need to remove the cover plate from the circuit breakers.
- Every breaker is located in an electrical bar that has the power.
- Do not attempt to tamper with these situations since they can be complex and dangerous for your life.
- If you know about breakers and plan of testing them, the only way is by using an electrical multi-meter.
- Be sure to set the multimeter to AC volts and touch one probe to the screw on the terminal on the breaker.
- The other probe should be in contact with the terminal block where the neutral wires have come together.
- If there is no power in the meter then the breaker is out of service.
Replacing the breaker
- One option is to replace the breaker if you find it to be defective.
- While replacing the breaker, double-check to make sure that your RV is disconnected from shore power.
- Ensure that your generator is also disconnected since the RV might connect to the generator if there is no power.
- Every single connection that goes to the circuit breaker must be cut off.
- Make sure you get the same breaker to replace the old one.
- A breaker with a different size is not going to work. Get an expert to do this job. Working on breakers is not an easy task, especially if there are major issues.
- As far as an RV plug goes, it is clear that you will need a 30 amp RV breaker to connect a 30 amp RV plug.
