You are watching: How many watts can a 30 amp breaker handle
We already know the RV has actually a 120 volt AC electrical system, so the is the an initial piece that information. Brand on appliances commonly identify the wattage and or amperage of the appliance, therefore this is the 2nd piece of information. An example would it is in attempting come use 2 120 volt appliances in ~ the exact same time that full 2,000 watts. The formula is 2,000 watts / 120 volts = 16.7 amps. If both of these appliances were used at the exact same time on the very same 15 amp circuit the circuit breaker in the RV would certainly trip.
one more example would be identify the maximum wattage capacity for an RV with a 30 amp, 120 volt AC electrical system. The formula is 30 amps X 120 volts = 3,600 watts. If friend exceed the total 3,600 watt capacity or the full 30 amp volume it is extremely likely the 30 amp breaker in the RV, or the 30 amp breaker in ~ the campground pedestal would certainly trip.
You can go one step more by looking in ~ the power distribution center in your RV. Friend will an alert there room several different circuits, identified by the individual circuit breakers. Let’s take a 15 amp circuit because that example, 15 amps X 120 volts = 1800 watts. A 15 amp circuit the is used exclusively for electrical outlets in the RV is based on the premise the you will not use every one of the outlets on the circuit at the exact same time, or use appliances that exceed the amperage rating. If for example you attempt to use a coffee pot and also an electrical skillet at the very same time, the 15 amp breaker in the power distribution box will most likely trip. This is why: The linked 16 amps X 120 volts = 1920 watts which exceeds the 1800 watt rating that a 15 amp circuit.
For gadgets in the RV that require much more amperage girlfriend will an alert larger sized circuit breakers in the power distribution box. For instance the roof waiting conditioner is top top a separate 20 amp circuit breaker. What is essential to understand here is if you effort to usage too countless power hungry gadgets in the RV in ~ the same time it’s feasible to damages the appliances and electronic devices. Stop say her roof wait conditioner is illustration 13 amps, you begin the microwave and it draws 10 amps and you placed some bread in the toaster drawing an additional 8 amps. In this situation you did no exceed any kind of of the individual circuits in the RV, however you go exceed the campground’s 30 amp organization resulting in the 30 amp circuit breaker tripping.
Living ~ above 30 amps usually comes under to security how plenty of appliances or devices you space using at the exact same time, and on what circuits. In a common RV with a 30 amp electrical service some the the strength hungry appliances and portable tools are the wait conditioner, electrical water heater, microwave, coffee maker, electric skillet, hair dryer, an are heaters and also a toaster. The vital to living on 30 amps is to no exceed the amperage that an individual circuit, and also to no exceed a complete of 30 amps at any given time.

With a better understanding of your RV’s electric system and also some basic electrical formulas you have the right to live comfortably on 30 amps with little to no problems.
