Five Skills of Choosing 50 amp RV Extension Cord 100 ft

by qin yan on April 16, 2022

One of the beauties of traveling in an RV is accessing power after settling. In a typical RV, different appliances are available, including fans, refrigerators, lights, stoves, power sources, stoves, etc.

While you'll have access to all these appliances, powering them is vital. To power any appliances, you'll have to connect your RV to a power pedestal using an RV power cord. If your RV is a 50 amp, you need a 50 amp RV cord. Suppose your power cord is short; you’ll need a 50 amp RV extension cord. Depending on the distance, you may need an extension cord up to 50 amp RV extension cord 100 ft. This guide discusses things you need to know about choosing a 50 amp RV extension cord 100 ft.

What Are Amp Extension Cords for RV?

RV extension cords are more like solutions to RV power cords that can't comfortably be connected to the power pedestals. Meaning extension cords are combined with RV power cords that are not long enough to connect to power sources. While the extension cord is essential, knowing the type of extension cord to use is more important.

The first step in determining this is to understand how to identify the capacity of an extension cord.

You should notice three letters written as "AWG." These letters stand for American Wire Gauge Rating. It would help if you kept in mind that for every extension cord, the lower the AWG number, the thicker the wire used for the extension cord, and the higher the rated capacity.

Also, the higher the AWG number, the less thick the wire and the lower the rated capacity of the extension cord.

For example, most cords in big box stores are either 14 or 16 AWG. These types of cords are excellent options if you're handling up to 15 amps or 1,800 watts which is nothing close to the capacity needed by your RV. Usually, RVs use 30 amps or, in some cases, can use up to two 50 amps 100ft which can handle up to 12 000 watts.

Now that you know how to determine the gauge of an extension cord, the next is to discuss the common types of amp extension cords for RV. Listed below are examples of amp extension cords for RV.

30 AMP RV Extension Cord

For this type of RV extension cord that can handle up to 3,600 watts, you'll want to get an extension cord of 10AWG. I hope you didn't forget that the longer the extension cord, the lower the AWG number needed. While getting your cord, you should look for all the information you need on the packaging.

50 AMP RV Extension Cord 100ft

Another type of RV extension cord is the 50 amp RV extension, and it can come in different lengths. You can have 25 ft, 50ft, or can be as long as 100ft.

Typically, a 50 amp RV extension cord should be able to handle up to 12,000 watts. Meaning you'll need a cord with 6 AWG. A common feature of the 50 amp is that it has four wires. Of these four wires, two are hot live wires, while the other two are neutral and ground, respectively.

The 50 amp RV extension cord is unique and different from others. It carries split phase power, which means that it has two 50 amp circuits and not just one. So there are 100 amps in total.
The Situation That You Can Use 50 amp RV Extension Cord 100 ft
The 50 amp RV extension cord 100ft is needed when the RV power cord can't get to the power supply cords.

For instance, say you got to your camping site and discovered that your 50 amp power is not long enough to connect to the power outlet, then you'll need a 50 amp RV extension cord 100ft. However, while using the extension cord, you must stick to the rules of using extension cords. They include;

Only use extension cords when there's a need for them.
Ensure there's a secure connection between all plugs and power supplies.
Ensure your connection plugs are not left on grounds where moisture can find its way in. You can buy a box or use a makeshift box for protection.
The Fabrication of 50 amp RV Extension Cord 100 ft

Make your own 50 Amp RV Cord

While buying a ready-made 50 amp RV extension cord 100ft is an excellent option. You can also fabricate one yourself. Some instances may warrant you to do this. It's also a perfect way to save costs.

To fabricate a 50 amp RV extension 100ft, you have to get needed materials, after which you'll fix them together.

Materials you'll be needing are; a six gauge cabling of your desired length, a 50 amp outlet, and a plug at the other end. Also, you will need short guards for wires so as not to get messed up.
How Long Can a 50 amp RV Cord Be?
Typically, a 50 amp RV cord is always between 15 to 25 ft long, but that doesn't mean you can't have something longer than that. You can have it as long as 100ft.

When thinking of the length of the 5O amp RV cord, you should keep in mind that the longer the length of your RV cord, the higher the possibility of voltage drops.

So, if you are having issues connecting your power cord to the power pedestal, and the distance you'll have to cover is up to 100ft, you can still solve this. An excellent way to solve this is to get a 50 amp RV extension cord 100ft. With this, you can easily connect your RV without any issues. While doing this, you should always check for voltage drops due to the long distance. This is because voltage drops can cause various problems with appliances in your RV.

How Far Can You Run a 50 amp Cord to a Camper?

Ideally, RV cords are 25 ft long, and you can connect them with an extension cord to the same amp. Once the power cord and the extension are 50 amp, you won't exceed the 50 amp ratings. However, it would help if you kept in mind that when the cords are too long, then voltage drop is inevitable. Thus, you shouldn't be too worried about how long but rather be about voltage drop. However, you can still run a 50 amp cord up to 100ft if you need to use the 50 amp RV extension cord 100ft.
