50 amp plug with 20 amp female plug

Hi, I am wondering if I can plug in my outdoor full fridge to a 50 amp plug. I need it to be connected to 20 amp female plug. I read I shouldn't use a 15 amp for a fridge, needs to be 20 because of the spiking that fridges have. We have a 30 amp rv and that is already plugged in. There is another plug on our site that's 50 amp and I need it to withstand the snow. Any help here is appreciated. I Don't want to break my fridge.

50 amp plug with 20 amp female plug

Just wondering is this fridge outside just a fridge like in your house. If so why does it need a 20 amp plug. Every fridge in our houses just runs off of a fifteen amp breaker. The problem with running your fridge off of that 50 amp receptacle going down to 20 amp receptacle is that if there is ever a problem with your fridge it will never ever trip the breaker that feeds that 50 amp receptacle. Most rv campgrounds will have a 15, 30, and 50 amp receptacles at the plug in at each site. If you can find a 15amp circuit somewhere it will be sufficient. Oh also I have been a licenced Electrician for 40 years..

By out door refrigerator do you mean a refrigerator like you would have in a house but it is sitting outside of your camper? Why do you not just use the outside 110 plug on the side of the camper? It should be a GFCI plug.

Yes it is OK
A fixture (Load) (Appliance) only draws the amount of current required.
If it is rated to draw 18 Amps that is all it will draw under normal circumstances. A fault is a different situation.
An 18 Amp fridge needs to be supplied with a slightly higher circuit (20 Amps) due to the amount of current the fridge draws when it first starts. This is normal.

The rest is all ok under normal circumstances.

It can be generally assumed - tongue in cheek - that any residential refrigerator will run on 15A. You have to understand start up v. running current draw. Any appliance takes momentarily higher current to start cycling if it has a motor, compressor, or any other high current draw. If other high load appliances are operating - AC, Furnace, water heater on elec., fireplace, and etc. then you will draw down the 50A total supplied to the site power pedestal. So long as total current used by all operating appliance at the same time is below the current supplied to the pedestal (50, 30, 20, or 15A) all appliances should operate properly. It's knowing what the pedestal truly has as supply, what your TT requires to function at peak usage, and what others in the park are consuming off of the line that supplies your pedestal. When summer peaks there is generally not enough power in a Campground to supply the entire park when everyone is running AC, fridges are maxed, fans are running, and everyone is operating an outdoor fridge.

When I owned a 30 amp camper I carried a 20amp fifty foot extension cord...I did so because when the DW was using the bathroom outlet and I had an electric hot plate pluged into the receptacle outside it would pop the breaker, so I would plug the hot plate directly into the campground pedestal...
