2 - 15 amp duplex receptacles (outlets)
1 - 50 amp RV cord end (plug)
15-20 +/- feet of 14/4 awg S/O cable (4 wire rubber coated cord)
Tools and skills
Assemble all components to create an extension cord you can plug into a 50A receptacle and have two 15A duplex outlets on one cord.
Red to one outlet line side, black to the other outlet line side, white to neutrals and green to grounds on both outlets. I use this outside at one of those plastic folding tables. Brew your coffee and cook your bacon and eggs without tripping breakers.
