Don, Nice catch on the 230V dryer connection. That would let the magic smoke out of the trailer appliances! Beckys, Please note that adapters don't change the amperage or voltage of a circuit. They only allow you to connect to different connectors. The feeding circuit voltage and amperage will remain the same. One thing to keep in mind is that many standard home circuits labeled 20 amp have 15 amp circuit breakers (14 gauge wire) and also that most long extension cords are 14 gauge which are limited to 10-15 amps. See a wire ampacity chart here: https://www.cepnow.com/cord-length-a...-rating-chart/
. Also, note that there is a voltage drop associated with long cords that will cause a heavily loaded appliance to draw more current to make up for lost voltage. For instance, I connect my 30 Amp trailer to a 15 amp circuit outside my house. I use a 75' 12 gauge extension cord. When I measured the voltage at the trailer with no load, I read 119 volts. When I started the Air Conditioner (I have a MicroAir soft starter on mine) the voltage dropped to 107 volts which will cause damage over time to the compressor. The extra current will also heat the extension cord and connectors which could damage them. Also bear in mind that when you connect to a power source and your batteries are low, the 12V
converter/charger in the coach will immediately draw 10-15 amps to begin bulk charging the batteries. Your fridge will also try to run on AC power at the same time. It's best not to use other appliances until the batteries have had time to bulk charge for a while. SO when you arrive at your "Moochdock" location (thanks for the term Don!) place the fridge in "LP only" mode if it has one then connect the power straight away and continue leveling/setting up the trailer and visiting with friends etc before starting to use any major appliances in the trailer. Happy Moochdocking!
