This is why you should never run outlets on circuits that use 14-gauge wire. This is because 14-gauge wire is not designed to carry 30 amps. If you want to run a 30 amp circuit, you must use a wire gauge of 10 or larger. Using the wrong one can damage your RV and cause major problems. Fortunately, RVs are covered in Chapter 5 of the NEC.

WIRE A 30 AMP RV PLUG CODE

After a basic wiring system class, they skim through code classes. Most electricians don’t go any further than Chapter 4 of the NEC. A 120 volt plug will damage your inverter, so you’ll want to use the right one for your RV. The difference between the two is the voltage between the prongs. The two prongs on the 30 amp plug are ground, while the four flat prongs will power a 50 amp RV.

WIRE A 30 AMP RV PLUG INSTALL

They can install a 30/50 amp receptacle near your motorhome.Ī 30 amp RV plug will have three prongs while a 50 amp plug will have four.

WIRE A 30 AMP RV PLUG MANUAL

To figure out which type you need, check the owner’s manual of your RV. Some RVs operate on 50 amps while others require 240 volts. When traveling, it is important to know which type of RV plug to use. In addition, they are easy to identify by their jackets. Eight-gauge wires are designed to handle at least forty to fifty amps at 12 volts, which makes them a good choice for kitchen appliances. A thicker wire diameter is safer than a thin one.Īnother important factor to consider when choosing wire is the voltage.

WIRE A 30 AMP RV PLUG UPGRADE

You can upgrade to a thicker wire if necessary. Generally, an eight-gauge wire can handle at least 50 amps. Copper has the highest amp rating, and aluminum wire has the lowest.Ĭopper wire has a high conductivity rating and is a better conductor than aluminum. In other words, the higher the voltage, the higher the amperage. There are a few factors to consider before putting 8 gauge wire on a 30 amp circuit. Can I use 8 gauge wire on a 30 amp circuit? Also, if you’re installing appliances that use a higher current, you should use a higher-gauge wire. For example, a refrigerator or air conditioner requires a larger wire than a microwave. The wire gauge you choose should match the size of the appliance. This rule is also called the 80% rule, and should be accounted for when choosing a wire size.Īnother factor to consider is how much current you need. If you plan to run a cable more than 100 feet from the sub panel, you should increase the wire ampacity by 20%. This distance is determined by the NEC’s 310-16 Code. A wire rated for 30 amps must have a voltage drop of 4.35 percent or less. While some of these factors are out of your control, there are a few guidelines you should follow.įirst of all, you must check the voltage drop. If you have an electrical installation project in your home, one of the most common questions that you’ll have is “How far can you run 10 gauge wire for 30 Amps?” There are several factors that will determine how far you can run a wire. How far can you run 10 gauge wire for 30 amps? When securing your wiring, use wire stapes, brass pins, or small straps to secure the wire. Once you’ve identified the proper wire size, you can begin to wire the outlet. Turn off the main breaker before wiring the outlet. It’s also important to consider the voltage of the outlet when wiring your RV. However, if you aren’t sure, you can always ask your electrician for assistance. A 10-gauge wire is the best choice, and a 12 gauge wire is not recommended for 30 amps. It’s recommended to use wires of at least 8-2 gauge for long runs and 10-2 gauge for short ones.īefore purchasing a new 30-amp RV breaker, you must determine the correct wire size and type. You need a wire with enough current carrying capacity to keep your appliances running without any problems. It is essential to choose the right wire size for your 30 Amp RV if you want to make sure you’re getting the most out of your electrical system.
