Hi,
As the various items are turned on, voltage may become lower and lower. The air conditioner may draw more and more watts as the day gets hotter. I've measured mine at 1900 watts. (Dometic 13500 btu)
1900/107 =~ 17.76 amps at my comfort zone of 107 volts.
24 amps continuous is what a 30 amp service can handle.
24- 17.76 = 6.24 amps for all other continuous loads. (about 667 watts)
At campgrounds when every one is running their roof air, and other loads, there may be voltage drop. It behooves the owner to monitor voltage. As the voltage drops there is much more risk of melting plugs.
My comfort zone is no lower than 107. I keep in my comfort zone by added an autoformer.
