What You'll Learn

Turn off electrical appliances and breakers
When connecting your RV to your home's electrical system, it is important to exercise caution. Failure to do so may result in damage to either your RV or your home's electrical system. Before plugging in the extension cord from your home to your RV, ensure that all electrical appliances in the RV are turned off. It is also important to turn off the breakers in your home.
If you do not turn off the electrical appliances in your RV and the breakers in your home, your breaker will likely trip. This is because RV appliances and systems can use a lot of electricity, and using multiple appliances at the same time can overload the electrical connection between your RV and home. Appliances such as TVs, DVD players, laptops, and refrigerators can be used simultaneously without overloading a 15/20 Amp connection in most cases. However, if you notice flickering lights or appliances turning off on their own, you have likely overloaded the electrical connection.
After turning off the electrical appliances and breakers, you can then plug the extension cord into your RV's electrical hookups via an adapter if necessary. Once plugged in, you can reset your home's breakers. If successful, you are set up properly and ready to use your RV. If not, and the breaker trips, unplug everything and check that all appliances in your RV are turned off and nothing is plugged in. Try the steps again. If the issue persists, refer to your RV's manual, contact the manufacturer, or consult a local electrician.
To avoid overloading your home's electrical system and driving up your electricity bill, try to avoid using all the appliances in your RV simultaneously. Additionally, consider using the appliances in your home or those of a friend or someone you know instead of running your RV appliances whenever possible.

Use an extension cord and adapter
Using an extension cord and adapter is a straightforward way to connect your RV to your home's electrical system. However, you should proceed with caution as you can damage both your RV and your home's electrical system if you plug in and expect everything to work normally.
Before you begin, ensure you have the right adapter. RVs generally have one of two types of power: 30-amp or 50-amp. A 30-amp power cord has one round prong and two angled flat prongs, while a 50-amp power cable has one round prong and three straight flat prongs. You can purchase adapters made specifically for RVs, called dogbone adapters, which consist of a short section of cable with different male and female ends.
If you have a 30-amp RV, you'll need a 30-amp female to 15-amp male adapter. For a 50-amp RV, you'll need a 50-amp female to 30-amp male adapter, which can then be connected to a 30-amp female to 15-amp male adapter. You can purchase these adapters online or at an RV supply store.
Once you have the correct adapter, turn off all electrical appliances in your RV and turn off the breakers in your home. Then, plug your RV cord or extension cord into the adapter. Plug the adapter into your household outlet by connecting the male end of the adapter to the outlet.
After everything is plugged in, reset your home's breakers. If successful, you're ready to use your RV. If not, your breaker will trip. If this happens, unplug everything and ensure all appliances in your RV are turned off. Try the steps again.
Keep in mind that when you plug your RV into a standard household outlet, you will be limited in the appliances you can use. Appliances like TVs, DVD players, laptops, and your refrigerator can usually be used simultaneously without overloading a 15/20 Amp connection. However, you may not be able to run multiple appliances at once, especially if you have a larger motorhome with a 50-amp hookup.

Reset breakers
Resetting the circuit breaker in an RV involves a few simple steps. Firstly, it is important to understand the functionality of a circuit breaker. A circuit breaker is a safety mechanism that protects your RV and its appliances from electrical overloads and short circuits. It acts as a safety switch that automatically shuts off the flow of electricity when it detects abnormal current fluctuations, preventing potential damage and fire hazards.
Now, let's go through the process of resetting breakers in an RV:
- Locate the Breaker Panel: The circuit breaker panel is usually located inside your RV in a convenient place, such as the kitchen, a closet, or near the entrance. It consists of a series of switches labelled with the various circuits they control.
- Identify the Tripped Breaker: Look for any breaker switch that has moved from its normal "ON" position to the "OFF" position or somewhere in between. The tripped breaker switch may appear red or may slightly protrude compared to the other switches.
- Switch Off the Breaker: Before resetting, ensure that the tripped breaker is switched off completely. Move it to the "OFF" position and make sure it is firmly in place.
- Evaluate the Situation: Before resetting, take a moment to assess the situation. Check if the RV is connected to an external power source and identify any potential causes of the breaker tripping.
- Identify Affected Circuits: Determine which circuits have lost power to pinpoint the relevant circuit breaker(s) that need to be reset. Different circuits power various appliances, lights, and outlets in an RV.
- Inspect Appliances and Devices: Examine the appliances or devices that were in use when the power failure occurred. Look for any signs of damage, loose connections, or unusual behaviour that might have caused the circuit breaker to trip.
- Unplug Devices: If possible, unplug all devices from the affected circuits. This step will help isolate any faulty devices causing the overload. After resetting the circuit breaker, reconnect the devices one by one to identify any problematic appliances.
- Reset the Breaker: Once you have completed the above steps and addressed any issues, you can reset the breaker. Flip the breaker back on, and power should be restored to the circuit.
Remember, safety should always be a priority when working with electricity. If you are unsure about anything or if the problem persists, consult a qualified technician or refer to your RV's manual.

Understand your RV's power needs
Understanding your RV's power needs is essential before connecting it to your home's electrical system. Here are some key points to consider:
RV Power Needs
Firstly, determine the amperage requirements of your RV. RVs typically have either 30-amp or 50-amp power systems. Smaller RVs usually have 30-amp systems, while larger motorhomes often have 50-amp systems. 30-amp RV plugs have three prongs, while 50-amp plugs have four prongs. Knowing the amperage will help you choose the right adapters and connections for your home setup.
Available Power Sources
Examine the power sources available at your home. Standard household outlets are typically 15 or 20-amp, which may not be sufficient for your RV's power needs. You may need to purchase adapters to safely connect your RV to these outlets. Dogbone adapters, for instance, are commonly used to connect RVs to different power sources.
Power Limitations
Understand that plugging your RV into a household outlet will likely come with limitations. You may not be able to run all your RV appliances simultaneously, and you might experience issues if you try to run power-hungry appliances for extended periods. Appliances like TVs, DVD players, laptops, and refrigerators can usually be used together without overloading a 15/20-amp connection. However, if you notice flickering lights or appliances turning off, you've likely overloaded the system.
Safety Considerations
Before connecting your RV to your home's electrical system, ensure all electrical appliances in the RV are turned off, and turn off your home's breakers as well. This will help prevent tripping breakers and potential damage to your electrical systems. Always use a surge protector when plugging your RV into a household outlet.
Adapter Requirements
Depending on your RV's amperage and the available outlets, you may need to purchase adapters. For example, if your RV has a 30-amp plug, you'll need a 30-amp female to 15-amp male adapter. If you have a 50-amp RV, you'll need a 50-amp female to 30-amp male adapter, which can then be connected to a 30-amp female to 15-amp male adapter. These adapters facilitate a safe connection between your RV and your home's electrical system.

Know your home's limitations
Before connecting your RV to your home's electrical system, it is important to understand the basics of RV power systems and your home's electrical system. RVs generally have one of two types of power: 30-amp or 50-amp. 30-amp RV plugs have 3 prongs and are larger than standard home plugs, while 50-amp plugs have 4 prongs. Smaller RVs typically have 30-amp systems, while larger motorhomes are usually equipped with 50-amp systems.
The limitations of your home's electrical system will depend on the amperage and the specific appliances and systems in your RV. Most homes have 15/20-amp outlets, which may not be sufficient to power all the appliances in your RV simultaneously. You will likely only be able to use one appliance at a time to operate within safe parameters. Running multiple appliances at once, especially those that are considered "electric hogs", can overload your home's electrical system and trip the breakers.
Additionally, consider the length of time you plan to connect your RV to your home's electrical system. Using your RV appliances and systems for extended periods can drive up your electricity bill.
To prevent overloading your home's electrical system, it is recommended to use your host's appliances whenever possible to conserve energy.
