Can I Run My RV Generator While Plugged In?

Can I Run My RV Generator While Plugged In?

RVs contain one or more batteries depending on the electric accessories that are present in them. Sometimes, these batteries die, and you cannot turn on the electric components. Generators are the backup power source to run these electric appliances when batteries become dead.

Can I Run My RV Generator While Plugged In? You can run RV generators while plugged in the power shore because these contain transfer switches that are helpful to switch your RV between various power supply sources. However, you should not do this because faulty transfer switches can damage inverters, electric systems, appliances, and batteries.

Many people directly connect their RVs to shore power to run the electric appliances and recharge batteries. It is better to plug the connectors into the shore power supply to decrease the battery load. Transfer switches are automatically operated that shift the electric supply towards stable and reliable sources.

Is it possible to run the RV generator while plugged in?

Using the generators and shore power sources simultaneously in your RV is possible because of the presence of transfer switches.

These automatic transfer switches are the safety components that protect the various electric appliances from damage when you unintentionally connect them with shore power.

These switches allow your electric system to connect with single power sources.

It does not allow the electric system to simultaneously use generators and shore power.

Sometimes, these automatic transfer switches become bad. These automatic switches fail to function because of damaged and loose electric connections.

Why you should unplug the RV when the generator is running?

You should not plug your RVs in shore power with generators because of the faulty transfer switches. These switches can get damaged because a high-power supply can overload the electric connections.

Damage to inverters

Inverters or power connectors are the devices present in RVs to convert the direct current source to an alternative current. Most electric appliances in trailers use alternative currents for their functioning.

These inverters help convert the direct current from the batteries to an alternative current to power electric items, including ovens, hair dryers, and refrigerators.

In addition, these are also connected to generators and power shores for conversion of current that is compatible with your devices.

Inverters can get damaged because of power surges and voltage fluctuation. The issue comes when you plug the RV in shore power and run generators simultaneously.

It can also increase fuel consumption because sometimes power shores are sufficient to meet electric needs. These can also cause environmental pollution and can affect the greenhouse.

Faulty electric system

Power shores connections and electric generators in your RV can directly affect the electric system because of overloaded circuits.

A high current supply can overload the electric circuits. Sometimes, these circuits are not designed to handle the high voltage current.

As a result, the circuit breaker can trip, and you cannot run any electric components with them. Tripped breakers break the electricity circuit and restrict its supply to the sockets.

You can identify the tripped circuit breaker by testing the electric sockets present in your trailer. It is necessary to check the circuit breaker when switches do not have an electric current.

Check the breakers and ensure that they are in the on position. In addition, high voltage currents can also damage the electric system, including short circuits in wires. Short circuits in wires damage the insulating layer and interrupt the current supply.

Affect electrical components

Electric appliances in your RV are designed to handle a specific amount of current. These can become faulty because of voltage fluctuations and high voltage currents.

These cannot bear the power surges and become faulty. Sometimes refrigerators, ovens, and hairdryers in your trailer stop functioning because of electrical faults.

In addition, several electric connections also contain fuse for the safety of their respective devices. You have to check their fuse and replace the blown-out one for their correct functioning.

Moreover, overloaded circuits also generate heat and lead to fire-related hazards. Inconsistent power supply also affects the performance of these devices and decreases their life span.

It is necessary to know the electricity capacity of your vehicle while connecting it with shore power and generators.

I always use energy-efficient devices that consume less electricity, so you do not have to use two sources simultaneously.

Damage batteries

RVs contain several batteries that get charging from the generators and shore power. These batteries also have inverters to convert DC to AC.

These batteries can last for 4 to 5 years, depending on their use, maintenance, and presence of electric appliances in your RV.

You have to charge these batteries by connecting the switches with power shores. These power shores charge batteries with the help of converters.

The issue comes when you turn on the generators, which can interfere with its supply. This interruption can affect the charging of batteries and lead to undercharging. Dead batteries cause issues during long traveling because an insufficient supply does not allow you to use the electric items.

You can also face problems because of overcharging of batteries. Two power sources running simultaneously overcharge the batteries and decrease their working efficiency.

Moreover, incorrect charging can also affect the battery’s health. These can also deplete quickly because of undercharging and not holding a charge for longer.

Why do people run RV generators when they are plugged in?

Many people do not unplug the RV switches from the shore power when turning on their generators.

People usually do this when they need more electricity to run various equipment. Generators supplement the power supply of the shore connectors to supply electric current to various components.

You can do this when running the various electric items simultaneously.

You can supplement your electric needs with these power-generating sources. In addition, these are beneficial when using high electricity-draining electric items.

I never run all electric appliances simultaneously because these can damage the system. Moreover, you should avoid using multiple devices at the same time.

Many people do this to reduce the fuel or gas consumption of the generators. It is also beneficial when you do not use them in the campgrounds because of their noise.

Campgrounds in different states have specific rules and regulations. You cannot turn them on if it is prohibited in your state. Do not run the generators and simply connect them with shore power.

Furthermore, these can also increase environmental pollution because of the release of harmful chemicals. You can use both during summer to use electric conditions without overloading and tripping the electric circuit.

Should I unplug my RV before starting the generator?

Disconnecting the shore power when connecting your RV with the generator is better. I always prefer to do this to protect the electric components from power surges and electric loads.

Moreover, it is recommended to use one electric source at a time so it cannot cause any serious damage because of voltage fluctuations.

Furthermore, you do not need an additional supply when you have shore-power connections. 

You can also use these connections when they are readily available in campgrounds and nearby spots.
