Know your RV's electrical system

Knowing your RV's electrical system is essential for safe and effective power usage. RV electrical systems typically use both AC (alternating current) and DC (direct current). The 12-volt DC system powers the electrical components of the engine and battery, while the 120-volt AC system runs appliances and power outlets. Shore power, provided by campgrounds or RV parks, is the primary external power source for RVs. It comes in 20, 30, and 50 AMP outputs, with 30 and 50 AMP being the most common. To determine your RV's shore power connection, check the number of prongs on the shore power cord; 30-amp plugs have three prongs, while 50-amp plugs have four.

It's important to be strategic with power usage, especially when plugging a 50-amp RV into a 30-amp plug or a 30-amp RV into a 110 VAC outlet. Avoid running multiple large appliances simultaneously, such as two air conditioning units or the microwave and air conditioner, to prevent tripping breakers or damaging the electrical system. Additionally, consider using a surge protector to assess the quality of the electrical hookup.

RVs usually have one or more batteries that provide power when no external source is available. These batteries can power essentials like lights, the water pump, and small appliances for a limited time but cannot drive heating or air conditioning systems. Batteries charge whenever an external power source is connected, including shore power, generators, vehicle engines, or solar panels. Solar panels are an alternative power source, with some RVs offering pre-installed panels or solar kits as an option.

Understanding your RV's circuit breaker is crucial for electrical safety. The breaker panel is typically located inside the RV near the floor or under the refrigerator, bed, pantry, or cabinet. In motorhomes, it may be in an exterior storage bay. The circuit breaker interrupts the power supply during an electrical surge to prevent electrical shock, fires, or damage to the electrical system.

Park, level, and stabilise your RV

Parking, levelling, and stabilising your RV is crucial for a comfortable and safe experience. Here's a step-by-step guide to help you through the process:

Park Your RV

Firstly, survey the campsite for any obstacles and hookups. Look for a relatively level surface, free from fire pits, trees, and other potential obstructions. Ensure you have enough space to extend your slide-outs and awnings. If possible, opt for a "pull-through" site, which requires no backing up. If backing up is necessary, position yourself to back in from the left side.

Level Your RV

Once parked, the next step is to level your RV. This ensures that your RV is straight from the front to the back and side to side. Start by adjusting the Tongue Jack or Landing Legs. Raise or lower them to achieve a level position from front to rear. If your RV has an auto-levelling system, follow the manufacturer's instructions. If not, you may need to use levelling blocks. Place these in front of or behind the wheels that need to be raised, then slowly drive your RV onto them until it reaches a level position.

Stabilise Your RV

After levelling, it's time to stabilise your RV to reduce unwanted movements and increase stability. This is done using stabiliser jacks, which are typically located at the corners or sides of your RV. These jacks help to reduce side-to-side motion and front-to-back movement. For RVs with an auto-levelling system, follow the manufacturer's instructions to activate the stabilisation process. If your RV does not have an auto-levelling system, use a manual crank or an electric drill with the appropriate socket to extend each stabiliser jack until it makes firm contact with the ground.

Finally, double-check the levelness and make any necessary adjustments. It is recommended to place blocks under the stabilisers for added stability.

Locate the power cord and surge protector

To locate the power cord and surge protector, you should first consult your owner's manual. In some RVs, the power cord is coiled up in the same driver's side compartment as your holding tank outlets. In other RVs, the power cord will be in a separate storage area.

Before plugging in your RV, it is important to park, level, and stabilize your RV. Ensure that your RV is exactly where you want it to be and that your power cord will reach the campground's outlet.

The electrical hookup for your RV is referred to as shore power, which is any power source provided by the RV park or campground. You will need to determine whether you have a 30-amp or 50-amp shore power connection. To do this, look at the number of prongs on the shore power cord; 30-amp plugs have three prongs, while 50-amp plugs have four.

It is recommended to use a surge protector to protect your RV's electrical system and the items connected to it. Surge protectors plug into the outlet where you would plug in your RV, and then you plug your RV power cord into the surge protector. This accessory acts as a buffer between your RV and the power of the electrical outlet, monitoring the amount of power from the outlet and ensuring no power spikes travel through your RV.

Some power cords have an indicator light that turns on when plugged in, but this does not indicate the quality of your electrical hookup. Surge protectors can help you determine the quality of the electrical hookup and protect your RV from poor electrical quality and surges, which can cause costly damage to your RV and sensitive electronic devices.

Ensure appliances are turned off

When hooking up your RV to an electric disconnect, it is crucial to ensure that all appliances are turned off. This step is essential for safety reasons and to prevent potential damage to your electrical system.

First, locate all the appliances in your RV, including the air conditioning unit, refrigerator, microwave, and any other electrical devices. Check each appliance to confirm that they are switched off. It is important to be thorough during this step to ensure that no appliances are inadvertently left on.

Next, locate your power cord and surge protector. These are typically stored in a compartment within your RV. Consult your RV's owner's manual if you are unsure of their location. Before plugging in your power cord, ensure that the power source is compatible with your RV's electrical system. Check the number of prongs on the shore power cord to determine if you have a 30-amp or 50-amp connection. Most RVs require a 30-amp or 50-amp shore power connection.

After confirming compatibility, it is imperative to turn off the breaker for your corresponding electrical service (30-amp or 50-amp). This step ensures that power is not flowing to the outlet when you make the connection. Failing to turn off the breaker before plugging in your RV can be dangerous and may damage your electrical system.

Once you have confirmed that all appliances are off and the breaker is switched off, you can proceed to connect the surge protector and then plug in your power cord. Finally, turn on the breaker to restore power to the outlet.

By following these steps and ensuring that all appliances are turned off, you can safely establish an electrical connection for your RV and avoid potential electrical issues or hazards.

Connect the power cord and turn on the breaker

Once you have parked your RV, located your power cord and surge protector, and ensured that all appliances are turned off, you are ready to connect the power cord and turn on the breaker.

First, check that the breaker for your corresponding electrical service (30-amp or 50-amp) is switched off. Then, connect the power cord to the campground power box. If your RV has a different amperage to the power box, you will need an adapter. If you are using a surge protector, connect it to the electrical stand first, before connecting the power cord.

Now, you can turn on the breaker. If you are using a surge protector, you should now check the lights or display to ensure that it is working. If you are not using a surge protector, you should now have power in your RV.

If you are plugged in but your batteries are not charging, you may need to flip the aux battery switch. If you notice your lights flickering or dimming, or your batteries are not charging fully, you may have a bad converter.
