How To Choose The Best Rated 50 Amp RV Surge Protector?

Deciding on buying the best rated 50 Amp RV surge protector may not be an easy task, more so if you are a beginner. You may not know what to consider about buying the best and that which will not disappoint. Below are some points to note.

  • LED Display

Nowadays, most manufacturers ensure to include a LED display in their surge protectors to help with monitoring. They do this by cautioning and indicating to you if there are any dangers with your power system. They indicate all the issues that occur due to wiring faults beforehand.

Hence, your surge protector needs to have an easy to read, bright LED display for easy operation and monitoring. This will help you avoid any catastrophes. All the lights on the display have different meanings, so be sure to familiarize yourself with all that information.

  • Rating of Joules

Generally, joules determine how much surge suppression a surge protector can handle or how much it can protect your RV from electronic damages. If your surge protector has a high joules rating, then this means it will protect your RV together with its components more.

Moreover, in case overheating occurs, a higher joules rating will perform at maximum compared to that with a lower joules rating. Besides, if you always experience frequent power surges in your RV, then it goes without saying that you will need a surge protector that has a higher joule rating.

  • Ease of Installation

You should get a surge protector that does not undergo complicated steps and procedures for installation. If you are a DIY lover, you would want to settle for an easy tool to set up without needing help from a third party. For example, the plug n play design is the easiest to install.

Because you are dealing with electricity, you would not want to make any mistakes because it would lead to unwanted damages. To avoid these, buy a surge protector that is simple to install and that which comes with an exact manual outlining carefully all the steps you need to follow.

  • Budget

How much are you willing to spend on a surge protector for your RV? As much as this is a matter of personal choice, you need to be cautious about it. Getting a cheap surge protector will cost you a lot in repairing the damages caused by it.

To be safe, buy a good quality surge protector for your RV that will offer you maximum protection and still serve you for a long time. Good quality RVs are somewhere between $100 and $300. Anything below this price tag is a cheap option, and we would therefore not recommend it.

  • Type of Appliances in your RV

Before purchasing a surge protector, it is essential to identify the electric appliances in your RV and the power consumption for each of them. This helps you know the kind of surge protector to buy for your RV. First of all, you must purchase a 50Amp protector for a 50Amp RV.

After identifying the power consumption needs of your appliances, you can comfortably make a sound decision. If you have an A/C, refrigerator, heater, and television, you will need a power surge protector for optimum protection in case of high or low voltage conditions.

What Is A Surge Protector?

A surge protector is a device that works by protecting or shielding your electronic appliances against any power surges or voltage spikes arising from transmission through your RV’s power pedestal. In case the power pedestal stops working, or there is a fault in the electric lines transmitting power, it may cause a surge in power.

This is where our device comes in. It blocks out any overheating that may occur due to the problems above, thereby protecting your appliances. Furthermore, in too low or too high voltage, the surge protector also protects against damages.

If you run your electronic devices on a voltage lower than 100V, the protector will switch off the power to avoid damages to your device. The same applies to if you use a higher voltage than normal for running your devices. They will all be save by the best surge protector.

Also, some problems may occur due to faults in your wiring system. They include; open ground, open neutral, reverse polarity, open circuit, and miss wired. A powerful surge protector sorts out all these issues. Do you now get why this device is a worthy investment?

Why Do I Need An RV Surge Protector?

A surge protector is an essential device for you as an RV owner. Just as its name goes, it serves as a protector for your RV and all its electronic appliances. Failing to invest in this will cost you a lot of repairs from the damages brought about by electric damages.

  • Protects against any poor wiring

Wiring problems in your RV will lead to trouble with your electric system, which causes a lot of damage to your electric appliances. If you are not sure about your RV’s wiring authenticity and cannot fix it, it is essential to invest in a surge protector ASAP.

  • Protection against low or high voltage

Connecting your RV’s power source to a power source at an RV park may cause you to be a little bit skeptical. This is because power spikes and high and low voltage conditions are a common occurrence in this place.

The surge protector automatically cuts out the power in case of these situations and reconnects when everything returns to normalcy.

  • Automatically switches off in case of dangers

These surge protectors are in such a way that they can sense danger, including voltage spikes and power surges within your power system, and automatically switch off.

Most RV surge protectors are weatherproof. This simply means that they are resistant to harsh weather conditions such as high humidity, rainwater, snow, heat, or even snow. Hence, you can place them outside, and they will not be affected by the changing weather conditions.

Portable Vs. Permanent Surge Protector?

There are two main types of surge protectors available in the market. You can either find a portable one or a permanent protector, depending on your needs.

The permanent surge features a permanent installation in your RV’s compartment, usually around the wheel area. This means you cannot move it around. The best thing about this type is that it is safe from all the harsh environmental conditions, including weather not stolen easily.

Also, this protector always connected to power for as long as your RV is in use. Therefore, there are minimal chances that you may forget to plug it in to keep your electronic appliances safe. However, they are not easy to install and need a pro for this.

How To Install 50amp RV Surge Protector

  • Step 1: Unplug RV from the power source

The very first thing to do before anything else is to unplug your RV from any power source. And if you are using a generator, switch it off as well as a precaution measure. After that, find a suitable location within your RV to place your surge protectors control box.

You should have a good view of the LCD display and consider the input and output sources.

  • Step 2: Cut power cord

After identifying a suitable location, get your RV’s power cord and cut it to about three and a quarter inches. Carefully remove it from the outer insulation of both the input and output cables. The next thing to do is stripping back each conductor 3/8 inches on both the input and output ends.

  • Step 3: Remove the cover from the control box

Get access to the control box of the surge protector by removing its cover. You will find six more screws inside it. Connect the ring terminals to the green input and output wires.

  • Step 4: Start the connections

Using the long cable that has plugs, slide in into the input side of the control box. Connect black to L1, white to L2, red to L3, and green to the ground screw. Reinforce the screws to ensure a secure connection.

For the short cable that comes from the junction box, you connect it to the T-2 output. The black wire connects with the sensor having a green tape while the red wire connects with the other remaining current sensor. The wire colors should match across the relay from each other.

  • Step 5: Double-check connections

At this point, you have to make sure that all the wire connections are correct and secure. But make sure not to overtighten the cables. You can then set the time delay jumper on the circuit board, depending on the manual instructions.

  • Step 6: Insert Display card

For display purposes, insert the display card and make sure that it faces you and should be in an upright position. Attach the control box with the six screws provided and then mount it to its position. The installation is now complete.
