Wire size on 30 amp RV cables
Do the commercial 30 amp RV cables you purchase from Camping World, Walmart, etc use #10 gage wire or larger? I have 2 of these, both 25 feet long and noticed a 10 volt drop when running the heat pump...

50 feet of #10 AWG 2 conductor cord should have a voltage drop of 3v with a current of 30A. Your 10v drop is somewhere else, the connectors or wiring to the pedestal. Or maybe your current is greater than 30A.
