RE: What gauge wire do I use

Got my answer. If I bought 6/3 uf-b cable, it would come with a 10 gauge ground wire so I guess my answer is a 10 gauge thhn wire would work for the ground.

RE: What gauge wire do I use

Everyone, thank you for all this advise. Since I am getting in deep on this, I have expanded the project slightly. The run remains at 200' (195' to be exact). I am thinking of doing this with thhn wire in conduit. I will run 6 gauge for trailer, an additional 10 gauge wire for a 20 amp outlet and a 6 gauge neutral wire. What gauge should my ground wire be? Should any of the wire gauges I mentioned above be altered? I am planning stranded copper. I'll price out the difference of this setup vs running 6/3 uf-b cable. Maybe I'm wastying my efforts and the uf-b cable would just be cheaper. Don't know. thinking outloud. Thanks!

RE: What gauge wire do I use

OK, 6 guage it is and yes this is a lot more expensive than I imagined. Before I spend this kind of money, what are the odds I would draw so much power that 6 is required. In other words, would normal everyday rv use require 6 gauge wire or would 8 be fine. Thanks again. 8 or 10 would be fine, but do it right, do it once... if you go with 6/3 (4 wires), you can technically upgrade to a 50 amp socket at the end of it, if you get a bigger trailer sometime down the road. or two 30 amp sockets, if you want to add a spot for a guest. Even if you dont see a bigger rig in the future, the heavier the wire, the better everything will work at the end of it. If you want to run your rooftop air, the electric hot water and say microwave at the same time, the heavier the wire the better. At the end of the day, I know you are right. Thank you!

RE: What gauge wire do I use

A search took me to: http://www.paigewire.com/pumpWireCalc.aspx where they recommended 4 AGW copper or 2 AGW aluminum for a 120 volt, 30 amp circuit at 200 ft with 3% tolerance. Change the tolerance to 5% and you can get by with 6 AGW copper wire. http://wiresizecalculator.net/ came back with 3 AGW copper wire with a 3% tolerance or 6 AGW for 5% tolerance for direct burial. 3% of 120 = 3.7 volts - 120v - 3.7 = 116.3v 5% or 120 = 6 volts - 120v - 6 = 114v I'd use the 5% tolerance figures. https://www.calculator.net/voltage-drop-calculator.html?material=copper&wiresize=1.296&voltage=120&phase=ac&noofconductor=1&distance=200&distanceunit=feet&eres=30&x=48&y=29 Agrees with these figures. I just finished typing my response above and now see your. This is all to complicated for me to understand. There must be some kind of code or standard as I do not know what the load will be but I know it will be less than 30 amps since thats where my camper breaker will trip.

RE: What gauge wire do I use

Wonderful calculator at calculator.net. Voltage Drop Calculator. Plug in Amperage used, distance and wire gauge and it will tell you the voltage drop in volts and percent. If you drop to 105vac, you will be on the edge of damaging electric controls in your appliances. Voltage loss will depend on actual amperage used on that length and gauge wire. Having an Electrical Management System like a Progressive Industries one will tell you actual voltage and protect from out of spec power. Even a Kil-a-watt via a 15-30 amp adapter will let you know of power variations as you turn on different appliances. I looked at calculators like what you described. The internet seems to complicate this subject with load calculations. My house was built having 15 amp circuits with 14 gauge wires and 20 amp circuits with 12 gauge wires. Nobody calculated any loads for each circuit - It's just standard code. I was thinking 30 amp circuit gets 10 guage but because my run is longer than 100 ft move up a size to get 8 gauge wire. The above poster mentioned 6 gauge which I also read but I also read the wire would need to be trimmed to fit in a 30 amp breaker. That's what makes me think that 6 guage is overkill. I just want to do it right. Thanks for all the input. I do appreciate it.

RE: What gauge wire do I use

6/3 or heavier for the future. Thanks. I was thinking 8, thinking 6 is a bit overkill. Why 6? Does 6 fit in a 30 amp breaker?

What gauge wire do I use

Hello, I want to place a 30 amp breaker in the panel of my house and then run about 200 ft of uf-b cable to a 30 amp rv outlet that I will place near my travel trailer. I would like to have the ability to use my travel trailer the same way as I would if I were at a full hookup campground. What gauge wire should I use? Thank you!
