Charging at RV sites

[Firebelly]

I don't believe a 50A breaker will deliver 50A continuous, except under ideal conditions. And, you're only supposed to draw 80% - so 40A - with a continuous load like an EV.

We charge at every campsite we stay at. I typically only plug it in after dark when everyone else's ACs and whatever else isn't drawing current, and then unplug it at ~7am when the kids get up and we start making breakfast.

The main concerns i've heard is that while each site may have a 30a 240v plug or whatever, that the whole system can't handle powering that all the time. So, that's why i only plug in once the campground folks are done their rounds, and once the overall power draw at the whole site is down considerably. Typically, around 10pm is late enough.

I also dangle a shirt or something over the truck charge port so it isn't flashing bright blue all the time, which helps folks not to notice. That, and park in a way so that it isn't super obvious that the truck is charging.


We run the trailer most times from our Ecoflow, so the powered site basically charges the truck up, tops up the ecoflow if solar wasn't enough, and can be a direct load if it's a scorcher and we need AC a ton.

A 50A breaker will deliver 50A continuous up until the moment it senses it is overloaded.

You are right that the maximum continuous load is 80% of a circuit's rating, so 40A. However, even that is pushing it.

This is exactly how I handle charges at campgrounds. Did it this past weekend.

I always book a 20/30/50 site. 30a to the camper, 50a to the truck using a 15-ft extension and the OEM mobile charger. Wish my 2024 could adjust the charge rate down a little. Would also be nice to have an option to turn off the charge port lights. Maybe someday we’ll get that update?

Partially true. A 50 amp breaker that is delivering 51 amps will trip in a time measured in HOURS. And that time will vary A LOT depending on several factors - temperature being the largest one. Even at 75 amps, will take a long time to trip. To get a 50 amp breaker to trip in a second will take hundreds of amps. Most people don't realize that it takes this long for an overloaded breaker to trip. Don't believe this, take a look at the time / trip curves for your favorite breaker.

With all this said, I AM NOT recommending planned overload of breakers or more importantly the wiring. As previously said, electrical code specifies 80% of breaker rating for continuous loads such as EV charging.

But we are talking about RV park breakers which tend to trip at below rated amperage….

I book a 20/30/50 site when I can and when I need to charge overnight. If I'll be at a site for several days, a 20/30 will do: 30 for the trailer and charge the truck off the 110/20.

I've had cases where there was only a 50A or the 20/30/50 tower was run off a 50A circuit. In that case the 50A goes to the truck and I run the trailer off the ProPower Onboard.

For the last trip I switched to an adjustable L2 charger. It was so nice to dial the charger back to only as much as I need and avoid stressing the system.

That was my thought when I read @K6CCC 's post as well.

A breaker that is tripping at below it's rating is failed and should be replaced. Does not mean that an RV park actually will do proper maintenance... Off hand I would be more inclined to believe that the RV park is NOT properly wired / breakered. For example a 30 or 40 amp breaker feeding a 50 amp outlet. Or maybe several 50 amp outlets wired to a single 60 amp (for example) breaker.

BTW at my house not long after I bought it, I kept having the 40 amp breaker on my central AC tripping. At one point I had a clamp on amp meter on the wire to the AC and was measuring 27 amps when the 40 amp breaker tripped. I replaced the breaker.

Easier to ask for forgiveness than permission. I have found the general public knows absolutely nothing about EV's and so you might get an easy answer of "no".

Get an EV charger that lets you downgrade the amperage so you don't knock some old timey RV park off the grid.

No one is going to know the difference between an AC running at 4-6kWH vs a EV charging.

We've pulled 3 different camper trailers in 3 years to Pymatuning State Park here in Ohio with our Lightning. Each time, we plug the RV into the 50A plug and we charge our Lariat with the 30A plug. I always keep several adapters just in case there's different style plugs. Each time, we use our Ford mobile charger and we charge every day while we're camping. We always stay 3 days and we always leave with 100 percent SOC. We love camping and charging with our Lightning.

I do exactly the same thing. I plug in the mobile charger to 30 amp plug at our favourite oceanside campsite. Love it!

FYI - On my 2023 XLT the blue charging ring can be easily turned off via a toggle switch at the Sync screen main panel ACCESS tile. I habitually do this while we're camping when I also turn on the Sync SILENT MODE.
