For a 50-amp aluminum wire, use No. 4 AWG. The smaller the number on the wire, the larger the wire diameter.
Similarly, you may ask, what size wire do I need for a 50 amp RV service?
A 50 Amp service is usual at 120 Volts. In order to get this services running, you need to have a #4 AWG copper wire in order to stay within a serviceable voltage drop, which is 3%. The major requirement in order to feed the circuit is a 50 Amp breaker.
Also, can 8 gauge wire handle 50 amps? 8 AWG may carry a maximum of 70 Amps in free air, or 50 Amps as part of a 3 conductor cable. David, if that cable is NM (Romex) then it actually cannot carry 50 amps.
Keeping this in consideration, what wire do I use for a 50 amp breaker?
The minimum wire gauge for a 50-amp breaker is eight gauge, and if the current draw is expected to remain close to the 50-amp limit for an extended period, you should use six-gauge wire.
How many amps will a #8 wire carry?

What’s the difference between 30 amp and 50 amp?
A 30 amp plug has three prongs – a 120 volt hot wire, a neutral wire and a ground wire – and is generally used on RVs with lower load requirements. A 50 amp plug has four prongs – two 120 volt hot wires, a neutral wire and a ground wire – that supply two separate 50 amp, 120 volt feeds.
What size wire do I need for 50 amp breaker?

Does stranded wire carry more current?
Because of the given thickness of stranded wire, i.e., it’s thinner, there are more air gaps and a greater surface area in the individual strands of wire. Therefore, it carries less current than similar solid wires can.
