All extension cords are not created equal
Mike, how much of a voltage drop can we expect when using a 25 foot 50 amp extension cord with the 30 foot cord that came with the RV?
A lot of this depends on the voltage drop at the pedestal. The generally accepted voltage drop using full gauge conductors by the NEC over a 100 ft run is 5%.
If you run the numbers on https://www.calculator.net/voltage-drop-calculator.html
it comes up with a 3-volt over 25 ft of 10 gauge shore power cord at 30-amps of current.
