A work around for low voltage.
Hi All, Due to the campground refusing to reserve a 50 amp site for me (three months in advance), I've been put where there is only a 30 amp outlet and the campground wiring is, shall we say, "chal...

Why would the electrical inspectors have passed such a poorly designed system? 120 down to 102 volts is a huge drop, there must be under-sized conductors in the branch or feeder circuits?
The more connections the more code allows the total to be derated.
The code is just not designed to meet the demands of modern RVs that pull 80+% of the available power near continuous.
36+ sites on one loop allows for just 41% of total.
Say 40 sites at 30 amp is 1200 amps. NEC say loop can be 492 amp total. Get a bunch like pianotuna and the voltage just sags away.
NEC 551.73
There are certainly other details and I am not an electrician but I think you get the point. What worked 30+ years ago is not adequate today.
