The majority of RVs are equipped with a 30 amp electrical system. Using the 30 amp electrical system in your RV is quite different than using a amp electrical system at home.

Before we get immersed in the topic, I think it is important to review some very basic electrical formulas.

30 amp extension cord wiring diagram diagram base website

If you understand these simple formulas you will begin to understand why a circuit in your RVor at the campground electric pedestal, is overloaded. These basic formulas can be used to answer questions based on what information is available at the time. We already know the RV has a volt AC electrical system, so that is the first piece of information.

Labels on appliances typically identify the wattage and or amperage of the appliance, so this is the second piece of information. An example would be attempting to use two volt appliances at the same time that total 2, watts. If both of these appliances were used at the same time on the same 15 amp circuit the circuit breaker in the RV would trip.

Another example would be determining the maximum wattage capacity for an RV with a 30 amp, volt AC electrical system. If you exceed the total 3, watt capacity or the total 30 amp capacity it is highly likely the 30 amp breaker in the RV, or the 30 amp breaker at the campground pedestal would trip.

You can go one step further by looking at the power distribution center in your RV. You will notice there are several different circuits, identified by the individual circuit breakers. A 15 amp circuit that is used solely for electrical outlets in the RV is based on the premise that you will not use all of the outlets on that circuit at the same time, or use appliances that exceed the amperage rating.

If for example you attempt to use a coffee pot and an electric skillet at the same time, the 15 amp breaker in the power distribution box will probably trip. For devices in the RV that require more amperage you will notice larger sized circuit breakers in the power distribution box. For example the roof air conditioner is on a separate 20 amp circuit breaker. Living on 30 amps basically comes down to monitoring how many appliances or devices you are using at the same time, and on what circuits.

In a typical RV with a 30 amp electrical service some of the power hungry appliances and portable devices are the air conditioner, electric water heater, microwave, coffee maker, electric skillet, hair dryer, space heaters and a toaster. The key to living on 30 amps is to not exceed the amperage of an individual circuit, and to not exceed a total of 30 amps at any given time. Every RVer should purchase a whole-coach surge protector to protect it against electrical problems at the campground.

Am I truly getting 50amp or is it half that. Would you recommend plugging a 30amp RV into 50amp whenever possible using the dogbone adaptor? My new Jayco fifth-wheel has a 50 cord. Does this indicate a problem, or is this just the way it is with this camper?

Great article! It is super important to study up on your appliances on your RV so you can get a baseline for your power consumption for standard items.

I have purchased a power surger that plugs into the power provided by the campground and then I plug the camper into. I bought the 30 amp one for my 30 amp camper. I will be honest, I have done basic electrical stuff outlet and ceiling fans and that is it, eletricity scares and confuses me.The amp service for an RV is volt with a 3 prong receptacle and a single amp dedicated breaker. Frequently it is confused for a NEMA 10—30 see below with disastrous results.

Due to the appearance of the TT plug, many people assume that it is to be wired for volt, but this is a volt device. Some receptacles do not have different color screws in that case attach the black wire at 5 o'clock or right hand side when looking at the BACK of the receptacle or the 7 o'clock frontal position the WHITE wire or neutral is connected to the silver screw or opposite side of the black wire and to the neutral bar in the panel.

As long as all the wires are connected to the correct terminals and everything checks out it will work. For a amp circuit, you can use gauge wire in most locales. For a long run, though, you should use the next larger size wire.

Here's a quick table for normal situations. The 5—30 is uncommon but it is available, twist-locking plugs and receptacles are generally used instead for high-current applications. This service is wired the same as the TT RV service. If you run across this all you need to do is replace the R with a TTR.

No Neutral. Typical uses: welders, large air conditioners 30, BTUkilns, shop machinery, and commercial equipment up to 2HP. NOT for RV. Typically used for older dryers that do not have a ground leg and that require dual voltage: V for the heating element and V for the controls and drum motor.

Frequently confused with the TT service with damaging consequences. Typically used for newer dryers that have a grounded plug and that require dual voltage: V for the heating element and V for the drum motor and controls. If you have an older dryer with a non-grounding plug that is, a 3-blade plug.

This service can be used for your RV as long as you make an adapter. It is amp on each leg or amp total at volt. The amp volt 2 pole 3 wire RV service. Click on photos to enlarge. This service is very simple to wire just follow the color coding for the connections if marked and use the correct size wire. The above amp volt service will supply 3, watts.

For a amp circuit, use gauge wire. Go up a size for more than foot runs, when the cable is in conduit, or ganged with other wires in a place where they can't dissipate heat easily: For V. If you have an older dryer with a non-grounding plug that is, a 3-blade plug This service can be used for your RV as long as you make an adapter.Forgot your Password?

Steve, Basically, on your schematic it shows they polars between the two hots as so if you choose to only use one hot in this cord you are fine to do so from what I see.

Most will use a cord like SJ Cord or simular to make this up So in closing Now don't hold me to SJ fella's for an extention cord I am on the road right now and do not have my code book with me View Public Profile.

Visit ElectricalMan's homepage! Find all posts by ElectricalMan. Thank you. This is a semi-related question. I'm also guessing it would not be safe to use the R for another extension cord from a different receptacle on the generator that is a " Volt 30 Amp Locking Receptacle".

Thanks again; Steve. Steve, I am sure they make a female end plug for every male attachment plug they make, Just a matter of finding it but again most places that carry the one will have the other. On the question of can you use the 20R female with the other end being a 30R I dont want someone saying.Electrical extension cords are a great way to extend circuits to areas that you are working, away from available outlets.

Sometimes we only need a short extension cord to give us the ability to plug our tools in and complete the project.

Then again, we've all had many times where we've had to tie many extension cords together to reach the area that we needed to reach. But how many extension cords can one tie together and still have the amount of power to power up those tools? Is it actually safe to keep adding extension cords to an existing circuit?

Well, there are some other factors to consider as well. How many feet from the electrical circuit breaker panel is the outlet that you are connecting to? It could be 50 feet away on the other side of the house. What is size circuit breaker the circuit connected to?

What size is wiring actually feeding the outlet that you are about to plug into? As you can see, there are many factors to consider beyond the reality of the extension cord. Many times, the user doesn't heed the extension cord size compared to the length of the run. They just grab any and all sizes of extension cords and put them together to get to the work at hand.

Long runs of wire encounter a variable that you may not have considered, resistance. Even though the copper wire is a very good conductor, it does have some resistance that causes heat. Heat does damage, not only to the extension cord itself, but also the power tools connected to them.

The voltage drop that occurs can heat up the motors of the tools that are attached to them. If you've ever burnt up a drill while using it in the series of examples we have provided, you now know what not to do. When you power up a tool like a drill and it runs slower than normal, it should now give you a warning sign of voltage drop and cause you to stop before ruining the tool. Most times, having a good, heavy extension cord or two to get to the area you need power can solve that problem.

Never run long runs of undersized extension cords and power heavy-load equipment like sump pumps, compressors, etc. The longer the run of wire, the more resistance, and thus, more heat. So how does this affect you? Well, power tools draw a certain amount of amperage to run both correctly and efficiently. This electrical load may be too great for the size of extension cord it is attached to. Because of wire size, the resistance of the wire, and the voltage drop due to the distance, these variables can damage both extension cords and the power tools that are connected to them.

Be sure to choose extension cords wisely by choosing a heavy gauge wire by following the chart that we have provided. You can plainly see the maximum amperage and wire gauge that can supply each over a number of feet of cord.

RV Power Cord Adapters

As you add additional feet of cord, the amperage availability gets less. Voltage drop in the cord often doesn't allow the power tools to run at full speed.

This causes them to heat up and often inflicts damage on them. Wiring inside the tools can melt as well as inflicting damage to the contacts. As the power tools heat up, so does the extension cords that they are connected to.

To be safe, try not to exceed the extension cord chart below. Be safe, not sorry. Extension Cord Length Feet Maximum Amperage Wire Gauge 25 10 18 25 13 16 25 15 14 50 5 18 50 10 16 50 15 14 75 5 18 75 10 16 75 15 14 5 16 15 Read More.After searching the Internet recently, we realized people needed a definitive extension cord size chart. This chart breaks down how both the wire gauge and length of the extension cord affects its ability to convey power to a corded tool.

Running a amp tool? How about a full amp tool? We can help you understand what length and gauge extension cord gets you and keeps you up and running. However, if you simply want to know what gauge extension cord you need to support a particular amount of amps, or how long an extension cord you can run without losing power, here you go.

Getting a firm grasp on understanding wire gauge and amps and how they interrelate can protect your tools and keep you safe. For our extension cord size chart calculations, we assumed V single phase with a power factor of 1.

We also utilized the NEC Chapter 9, Table 9 numbers for impedance and voltage drop calculations. With that being the case, only one of our recommendations hit that level, the foot gauge extension cord with a full 15A draw. This might be an unusual application for some, but we felt it represented a great scenario. It helps you understand what happens when using a foot extension cord on a tool with a high current draw. Everyone on a job site or remodel has some experience with running extension cords.

You have to ensure that if your tool requires 15 amps, it gets 15 amps. But, you also do something worse. First, you can tax the tool motor—causing it to work harder to draw the energy it needs to run. Think of this like trying to breathe through a straw.

Secondly, you potentially create a dangerous situation.

An undersized extension cable will heat up over time. Use it in that state for too long, and the wire insulation could melt. This particularly holds true if you keep the wire in a coil, which creates resistance and a magnetic field that heats up. Understanding wire gauge and amps and how to properly size your cords for the tool and distance can make your tools last longer and run more optimally.

Connect with.An extension cord also called an extension lead or power extender is a power supply expanding the box. It is similar to the wiring of a switch box which is connected to an extended input supply cable.

To make an extension cord, get an electrical wire with appropriate length. Try to choose the minimum length as required. Because the length increases the electrical resistance and thereby the copper loss. Usually, all the socket will be similar to match the plug of extension cord. Or use multiple types of sockets. The wires and the parts should satisfy the power requirements. Depending the loads which may be used, choose a cord cable with proper wire gauge. Extension cords should have a minimum of 16 AWG.

And the rated load power should be at the limit of amperes the chord can drive. If available, it is recommended to wire circuit with standard colour codes. Because it helps to identify the lines during wiring and also if any chance of maintenance occurs. Commonly phase, neutral and ground connections have red, black and green respectively.

The colour codes followed may vary with countries, in most countries ground connection has green.

To protect the cord from over current, install a fuse inside the extension cord for the rated power capability. A fuse can be added in the phase line before the first switch in the circuit.

Keep extension cord cable protected from physical damages. Make sure it has proper insulation and avoid chances of contact with water or wet surroundings. The coiled structure causes inductive reactance or impedance across the coil and drops voltage across the wire.
