In 2000 I bought a new 5th wheel with 50 amp service. there was a 50 amp breaker box in the front compartment. A 30 amp breaker fed the other breaker box on a 12 gage 20 amp wire which supplied the rest of the coach. A 15 amp breaker supplied the water heater and hair dryer. every time you showered and then tried to dry your hair the breaker tripped. The other side of the 50 amp service on had the plug for the washing machine and 2nd air conditioner on it which I did not have. I did… Read more »

Even though the receptacle found in your RV is rated at 120 VAC, the 50-amp shore power is actually a 120/240 VAC four wire service. The acronym VAC stands for “Volts of Alternating Current” which means the voltage is constantly changing from 0 volts up to 120 volts Positive back down to O volts, then it goes to negative 120 volts and then back up to 0 volts. This happens sixty times a second. This is commonly referred to as 120/240 VAC 60 HZ (Hertz). The actual electricity that feeds your 120 VAC receptacle in your RV comes from your… Read more »

I read Mikes article about the difference between 20, 30 & 50 amps. He makes it sound like if you have 50 amps you can run everything! I have 50 am service but if I run more than 20 amps on the one circuit that serves the kitchen, living room & bathroom the 20 amp breaker on the inverter trips. The micro, water heater and A/C are on their own circuits. Strange way of wiring, so the 50 amps does me no good if I want to run the coffee maker, toaster oven, hair dryer, crock pot, etc at the… Read more »

I was just about to post a very similar comment — having 50A service doesn’t get around limitations on grossly uneven demand distribution — it just means you can run more things on different circuits at the same time (so, you can keep AC on while microwaving coffee and your wife blow-drying). All your 15A/120V outlets are often ALL on the same breaker (so using plug-in heater, toaster, blowdryer at once is a no-no!). If RV designers were smarter, they’d use the 50A service more like a house, and have multiple “plug” circuits (preferably overlapping in the kitchen particularly!), but… Read more »

My wife keeps saying “but we have 50 amps” why cant I run all those things?
And when that breaker trips I have to go outside to a basement storage where the inverter is located, get on my knees and reach 3′ inside to turn it back on.
Very poor design. Why not have this breaker located inside with all of the other breakers in the panel?

Hi Chuck. I”ve enjoyed your newsletter for years. This week I learned two things from the Solo article. It suggested leaving id in the rv when hiking alone and also letting a neighbor know. I would love to read a weekly column for solo rv’ers! There are more of us out there than you might guess. Those tips were both invaluable. Thanks for your consideration. Judy
