Midwest BR54U - 50 AMP RV Receptacle BR54U
50 Amp RV Receptacle. 120/240V AC, NEMA 14-50R, 3-Pole, 4-Wire, Straight Blade, Grounding.
It's a Midwest brand receptacle, that all our power boxes in our RV Park require. Just wish people would quit driving off without unplugging and breaking them. Galesburg's price is great on them.
I love these outlets for use in Midwest RV boxes. They are designed for that use and they fit great.
