![]() This plug is wired to a 120-volt breaker panel that powers your 120-volt devices and a converter charger. ![]() The wiring that runs your RV (and conveniently powers all the electrical gadgets that we love and need) is getting its energy from a huge electrical cord that is connected to a pedestal with outlets in the RV park. Here is how the complete RV wiring looks like:Īn this is a PDF file of the schematic diagram and a PDF file of the wiring diagram. Well, there is some space on the roof, right? Using a generator will allow you to power larger appliances if you have a very limited power service. It is not really an option if you don’t want to damage your batteries! Some models offer a “power-assist” option, where high surges could be directed to another source of power if the main one cannot handle it. This device will assist you in automatically transferring power from your 120-volt shore power, batteries, and a generator. Higher-end inverter-chargers include transfer switches as well. That is in case you would like to save on space and instead of getting two devices (inverter and converter), you can have one that combines both. Now, let’s talks about “optional devices” that will really help you with having an exceptionally comfortable RVing experience: Also, it can convert 120-volt shore power into a 12-volt DC power supply that is used for your lights and few other DC-powered devices that you probably have. ![]() If you are serious about camping, you need a device that will charge your batteries. You will need this device to converter 12-volt battery DC power into 120-volt AC power, that some of your appliances probably use (like residential refrigerator). A good set of batteries is a must-have in RV if you ever want to get away from shore power. Here are some of those devices that any RV must-have: Now, you understand why the electrical system in RV is a multitude of power devices that are there to support you and your lifestyle. Here is the schematic PDF and this is the wiring PDF. You can download here PDF version of this picture for greater detail.ģ-way Transfer Switches change the power output between inverter (and battery bank), shoreline power, and a generator to give your RV all the power you need, any time you need it! So how do you interconnect them all? An ALL MIGHTY Automatic Transfer Switch (or Changeover Switch) will help you out with this complicated task.Ģ-way Transfer Switches change the power output between inverter (with batteries behind it) or shoreline power, to supply your RV with electricity: Solar panels could also assist you in refilling your battery bank while out there on the road. 12-volt DC power is usually sufficient for many applications, including lights.įor larger things in your RV, you may want to utilize the GREAT POWER of the generator. AC power is commonly used in our houses and it is also the same power supply that is coming from a pedestal in the RV park.Įven though everything (besides computers) in our houses is powered by AC, not many things in your RV use this type of power supply. This type of power converter or battery dependent.ĪC (or Alternating Current) is a current that periodically reverses or alternates directions. It is the same type of outlet that is known as a “cigarette lighter”. 12-volt refrigerators (two-way or three-way).It’s the same type of energy that is stored in your RV’s batteries. The chassis power system is connected to the RV electrical grid and controls all vehicle-related power gadgets, lamps, etc.ĭC (or Direct Current) is an electrical charge that flows in only one direction and is commonly used in electronic devices. ![]() RVs are generally wired for two different types of services, 30-amp, and 50-amp.ĭirect Current (DC), Alternating Current (AC), and chassis (or vehicle) power are the three main electrical systems in your RV. RV’s electrical system consists of a 120-volt AC circuit (that is powered by shore power or battery power through the inverter) and a 12-volt DC circuit, which is powered from the battery, or shore power through the converter. ![]() FOR MORE INFORMATION, PLEASE READ MY EARNINGS DISCLAIMER.
