RV Electrical Power Distribution Panel
Most RV’s that are travel trailers or larger have an RV electrical panel board for distributing power. This is how electrical energy gets routed within your RV as well as protected within your RV.
On motorhomes and fifth wheels, the distribution panel boards seem to be located by the stairs near the entry of the RV. On the travel trailers, they are usually located in a centrally located bathroom. I’m sure many exceptions to this apply, but this is what I’ve seen in many of the RV’s I’ve seen.
Shore power comes into the RV and is routed to the panelboard. The panel board then sends the electric power from the shore power to breakers (on off switches that also protect your RV in case your RV starts taking too much electric for the wires to handle). You can see the breakers in the panelboard in the picture.
From the breakers, the electric power then goes to air conditioners, TV’s, and different AC power places inside the RV.
One of the breakers goes to a thing called a converter. The converter does 2 things:
- Turns AC power into DC power for the DC powered systems
- Charges the battery for those times when AC power is not present
The AC power goes to the converter from the breaker.
Then the DC power out of the breaker comes back to this panelboard where it breaks the DC power into its own set of fuses and places the DC power needs to go. You can clearly see the fuses on the right hand side of the panel board below.
Remember, on your RV, there are many things that you can utilize with only DC power. The only things you can’t run are the TV , the microwave, and the air conditioners.
So anyway, when you start having power issues for some reason or the other, you will eventually have to visit the distribution panel board and it will become an old friend.
