Starting from the pedestal: the 50 A male to 30 A female adapter will connect one of the two 50 A pedestal circuits to the single hot lead of the 30 A cable. If you have a 50 A coach and a 30 A extension, the pedestal has a 50 A outlet, and you can't reach the pedestal with just your 50 A cable you might be tempted to use this combination: Your 50 A cable, then a 50 A to 30 A adapter, then your 30 A cable, then a 30 A to 50 A adapter so that you can plug into the pedestal's 50 A outlet. In the discussion of 50 A and 30 A extension cables, it should be noted that there is one combination that actually presents a fire hazard and not just a reduced voltage problem. That will tell you if your cable is too small. No matter what size you have, when you have a heavy load, go and check each plug and cord for heat. I have both and for the addapter I made my own out of the same guage size of my 50 amp cord. They can tell you the guage size you would need.Īlso, as was said, you could buy a 50 amp extension cord. Then take a trip to your local electrical suppy house and ask them what size guage stranded wire you would need to carry 120 volts/50 amp power 52 feet. Check the extension you wish to buy for the same information. The wire guage will be stamped or imprinted every 12 to 18 inches. I don't want to lose voltage as well.ĭon, look at your 50 amp cord. cord with a dogbone in the middle? And if we do, how much.

Do we lose any voltage by having what will end up being a 52 ft. extension cord for an upcoming camping trip.
