AC voltage and line loss

Thanks guys, I know I can’t just add a 50 amp breaker. I was referring to the post about all breakers on a branched circuit have to handle 125% load.. yet they didn’t follow that in RV’s

The problem with a lot of RV parks is that they tend to skimp on the wiring used for ALL of their pedestals. When this happens, and you get a lot of RV's all trying to run their AC units the voltage drops. Any drop in voltage increases the amount of current/amperage needed to run the AC unit.
To explain, lets say that your AC unit, or any electrical appliance needs 1200 watts to operate. At 120 volts it takes 10 amps. If the voltage drops to 108 volts, then it takes 11.1 to operate the appliance or a little over a 10% increase in amperage.
This 10% increase in amperage becomes critical when you have several RV's trying to do the same thing. There have been many people that have had appliances damaged by low voltage so it is something you want to try to avoid as much as possible.
