The more I read, the less I understand.
Somebody has probably addressed this dilemma somewhere in this forum... but I haven't found it.
My son recently bought a fifth wheeler with a 50 amp, 3 prong female connection. The RV came with a 50 amp 15 foot, 3 prong female to 4 prong male cable
. The RV is located 65 feet from his power pole which has a 50 amp, 4 prong connection.
My son bought a 75 foot 50 amp cable which has 4 prong connections (male & female). (Something like this: (50 Amp - 75 ft) RV Extension Cord with Pull Handles and Lighted End (9513T)
If he connects the 75 foot cable to the 15 foot cable, everything works, but he would prefer, to keep the run as short as possible, just use the 75 foot cable.
How can he connect his 50 amp 4 prong 75 foot cable directly to the RV 50 amp 3 prong connection? Does somebody sell a 50 amp 4 prong male to 50 amp 3 prong female connectors? (I have found 50 to 30 amp cables but not 50 to 50 amp.)
If a connector does not exist, where can he find a short, 1 foot 50 amp 4 prong male to 50 amp 3 prong female cable?
