Whether you’re traveling or your RV is parked at your residence, it’s crucial to connect it to power for utilizing appliances and charging the RV’s battery. Most campgrounds and all RV parks offer power supply boxes equipped with various electrical outlets that can be plugged into. Alternatively, you can connect your RV to a household electrical outlet. Either method is relatively straightforward. It's advisable to carry a selection of adapters in your RV, ensuring you can connect to power wherever you travel!
Steps
Choosing the Right Adapter
Determine the amperage of your RV’s power cable by counting the prongs. A 30-amp power cord typically features 1 round prong and 2 angled flat prongs, while a 50-amp power cable has 1 round prong and 3 straight flat prongs.
- Understanding the amperage of your RV’s power cord helps in selecting appropriate adapters for connecting it to a power source.
- RV electrical cables are usually stored in a compartment on the lower backside of the RV exterior or can be found loose inside the RV, requiring connection to the external electrical outlet on the RV’s exterior.
Survey the available outlets to determine the necessary adapter. A receptacle with 1 circular hole and 2 diagonal flat slots corresponds to a 30-amp power cable, while a receptacle with 1 circular hole and 3 straight flat slots corresponds to a 50-amp power cable. Standard home electrical outlets, featuring 1 circular hole and 2 straight flat slots, typically support 15 or 20 amps.
- Once you ascertain the available power outlets and the type of power cable your RV employs, you'll know whether direct connection to the power supply is feasible or if an adapter is required.
- Most power supply boxes at campgrounds and RV parks offer 2-3 different outlet varieties.
Choose an adapter with a female end matching your RV’s power cord. Opt for an adapter featuring 1 circular hole and 2 diagonal flat slots if your RV utilizes a 30-amp power cable. Select an adapter with 1 circular hole and 3 straight flat slots if your RV employs a 50-amp power cable.
- The female end refers to the part where you insert the power cord.
- You can acquire RV-specific adapters known as dogbone adapters, comprising a short cable segment with differing male and female ends. Dogbone adapters are available online or at RV supply stores.
Opt for an adapter with a male end matching the highest-amperage outlet. Choose an adapter featuring 1 circular pin and 2 diagonal flat pins if a 30-amp outlet is accessible. Select an adapter with 1 circular pin and 3 straight flat pins if a 50-amp outlet is available.
- If you're plugging into a standard home electrical outlet, utilize an adapter with a male end comprising 1 circular pin and 2 straight flat pins, designed for 15- or 20-amp electrical outlets.
Connecting to a 30- or 50-Amp Power Source
Attach the appropriate dogbone adapter to your RV’s power cable. Retrieve your RV’s power cord from its storage compartment on the RV's exterior. Plug the power cord into an adapter with a corresponding female component if the power cable doesn’t align with the available outlets.
- For instance, if you possess a 30-amp RV cable and the power supply box features only a 50-amp outlet, utilize a dogbone adapter equipped with a 30-amp female end to connect your RV power cord and a 50-amp male end for the power supply connection.
Ensure all electrical systems in your RV are turned off before connecting to the power box. Turn off your RV’s electrical system and verify that all appliances inside are switched off. This precaution helps prevent electrical surges and other potential accidents.
- Many RVs come with built-in surge protectors to safeguard against damaging electrical surges. If your RV lacks one, consider having one installed.
Pro Tip: You can utilize this method to connect your RV to a generator if a power supply box isn't available. Opt for a generator with a minimum capacity of 3500 watts.
Disable the breaker at the power supply box before plugging in your RV. Locate the breaker switch on the power supply box and switch it off to cut off the power supply while connecting your RV.
- This precautionary measure guards against dangerous electrical surges when plugging in. Always connect your RV to a power supply with the electricity switched off.
Insert your RV power cable into the outlet on the power supply box. Insert the prongs into the corresponding holes and slots in the outlet. Ensure the plug is fully inserted, sitting flush against the outlet.
- If using an adapter, verify the connection between the RV power cable and the female end of the adapter after plugging the male end into the power supply box.
Restore power by switching the power supply breaker back on. Return the breaker on the power supply switch to the on position to provide electricity to your RV. Your RV is now powered up, allowing you to operate all electrical components and charge the battery.
- Connecting an RV to a power supply box at a campground, RV park, or elsewhere is commonly referred to as shore power connection. This enables you to operate all electrical systems in your RV and recharge the battery.
Connecting to a Home Electrical Outlet
Insert your RV power cable into a dogbone adapter featuring a 15-amp male end. Opt for a dogbone adapter with either a 30-amp female end or a 50-amp female end, depending on the type of power cable your RV utilizes. A 30-amp power cable is equipped with 3 prongs, while a 50-amp cable has 4 prongs.
- If you don’t already have one, these adapters are available for purchase online or at RV supply stores, typically priced around $15 USD.
Pro Tip: When shopping for an adapter online, you may need to specify the type of male and female ends you require from a condensed list, such as 15M/30F. The numbers represent the amperage, while the letters denote male and female.
Deactivate both your RV’s electrical systems and the home’s circuit breaker. Power down your RV to prevent the battery from draining, ensuring all electrical appliances and systems inside the RV are switched off. Flip the switch on the home’s circuit breaker panel to disconnect the electrical supply to the outlet you intend to use.
- This precautionary step prevents the risk of tripping a breaker switch when connecting your RV to the home’s electrical outlet.
Plug your RV’s power cable into the home's electrical outlet. Insert the 15-amp male end of the dogbone adapter into an available home electrical outlet. Ensure that the RV power cable is fully inserted into the female end of the adapter.
- It’s advisable to plug your RV into a dedicated home electrical outlet that isn’t in use for other purposes. Ideally, the outlet should be on a separate breaker circuit to avoid tripping the breaker due to excessive electricity consumption.
- If the power cable and adapter don’t reach the electrical outlet, employ a heavy-duty extension cord to bridge the gap.
Activate the power supply to the outlet using the breaker. Switch the circuit breaker corresponding to the outlet where you plugged in the RV back to the on position. This action will commence the supply of electricity to your RV.
- Even if you don’t intend to use your RV while it’s parked outside your home or someone else's, it’s advisable to connect it to power. This ensures that the RV’s battery will charge while it’s in storage.
Minimize your usage of appliances in the RV whenever possible. Utilize indoor home facilities for appliances such as hair dryers or microwaves, if feasible. Running multiple appliances simultaneously or operating those with high electricity demands may trip the home’s breaker, disrupting the electrical supply to your RV.
- For instance, attempting to power the RV's air conditioning system from a home electrical outlet is not feasible.
Useful Tips
-
If your RV lacks a built-in surge protector, contemplate installing one to safeguard your RV’s electrical systems against detrimental power surges.
-
A 30- or 50-amp power source will typically accommodate all RV systems without issues. However, if you must use a 15- or 20-amp home electrical outlet, endeavor to limit the use of electrical appliances and refrain from operating large systems such as the air conditioning.
Warnings
- Always treat all electrical wires and outlets with caution, assuming they are live, even if recently turned off. It's crucial to exercise extreme care when dealing with electrical connections to prevent accidents.
