Most panel lugs are not only aluminum rated, they are made of aluminum. All connections of this size are properly rated for aluminum wire, and torqued to spec. There is nothing wrong with aluminum at these large sizes they are proven reliable. Presumably you'll bring it to an "RV stand" panel which typically has a 50A RV outlet and 20A GFCI, or alternately also a 30A RV outlet. What is the Wire Gauge Required for a 50-amp. If they are wired onto the same phase, that's "the hard way to do it" and you would need much larger wire. The appropriate 50 amp wire size is 8 gauge aluminum or 6 gauge copper. According to the American Wire Gauge system, the correct 50 amp wire size is 6 gauge. Have your RV mechanic make sure they are balanced thusly. Wire Size: 14 AWG of Conductors: 3 Conductors: Conductor Material: Bare Copper: Stranded or Solid: Stranded: O. 60 amp wire size is either 6 AWG or 4 AWG wire (AWG stands for American. Presuming that your A/C units are wired into opposite phases on the RV panel, this will work very well. 6 gauge thnn wire in conduit is good for 60 amps. 6 gauge Romex is only good for 55 amps so you would have to use a 50 amp breaker limiting you to 40 amps. Let’s talk about this in a little more detail. You have to remember that charts don’t account for distance, only ambient. You can consider that as the maximum limit for how far will 6 gauge wire carry 50 amps safely. However in the new 2020 CEC electrical code you are permitted to use 8 AWG which is normally rated for 40 amps to be installed on a 50 amp breaker with some terms and conditions. NM, TW, & UF WIRE (Copper Conductor) SE CABLE (Copper Conductor) 14 AWG - 15 AMPS: 8 AWG - 50 AMPS: 12 AWG - 20 AMPS: 6 AWG - 65 AMPS. Copper and aluminum are the two most common cables used for wire, and they have different wire sizes for the same amperage ratings. Your standard wire size chart will tell you that 6 AWG wire, which is rated for 55 amps, should be the wire size for 50 amp circuits. That requires a 60 amp circuit as 80 percent of 60 is 48. As a whole the wire size for a 50 amp breaker is 6 awg. It enjoys "economies of scale" because of its popularity.īut when you calculate the voltage drop for your application, it fits perfect at 2.97% voltage drop at 40A draw (far more than you'll use most of the time think "both A/Cs and the dryer running). The Tesla gen 3 wall charger had a max charge rate of 48 amps. But it fits hand to glove for the application - underground feeder going to a remote site. Well, not this exactly it's made for 100A main feeder for mobile homes.
