Thats not always a static figure, mind you, since its also affected by other factors such as wire count and material. Although voltage drop will not matter for short distances, it matters when the distance between the two points is more than 100 feet. The biggest priority when considering what size wire for a 150-foot run is safety. The next step is to ensure your main panel has enough amperage supply to power the required subpanel. All in all, even though 6-gauge wiring is suitable for 60 amps, 4-gauge wiring is the better option. One must thoroughly understand the right wire size and their amperage load-carrying capabilities for this specific purpose. The breaker should also be from a reliable manufacturer with some proof of testing available. That will be more than sufficient for a 60 amp service 65 feet away. What would be a good size wire. For a thorough look, you can check out this table. But if you have a sub-panel 150 feet away, you can use 3 AWG wire, which can handle 100 amps. I may run one saw at a time or a couple of saws. Its imperative that we also use Chapter 3: NEC CODE Wiring Methods and Materials rules (specifically NEC 220-2 and NEC 310-16 rules), which include: Now, if you consult the AWG gauge wire size chart here, you can see that: Lets look at these two rules closely.

I'm mostly known for my knack towards all things electrical, as can be clearly seen from most of my work. As can be seen from the above chart, with the increase of amperes of any circuit, so does the thickness of the wire. Now, measure the voltage drop of the distance you have measured and convert it to decimal. The wires diameter is indirectly proportional to its wire number. Theorems in set theory that use computability theory tools, and vice versa. The result would not change for aluminum wires. The breaker trips because of ambient temps and radiating heat. This will also help to choose the correct wire for your use case. Thank you for the lesson. 50-60 amps should do the job for most people and the wire gauge you should choose to pair with a 50-60 amp breaker should be 6. How Does the Wire Size Affect the Sub Panel? According to the NEC code, the wire size depends on some particular facts. This is something you must avoid at all costs. A gauge that is too small can lead to disaster. Speaking of the 6-gauge wire, it can handle a whopping 75 amps at 194 degrees F. Keep in mind that a 4-gauge wire handles 70 amps at the standard 140 degrees F. As you can see, the ambient temperature can make all the difference. I am Edwin Jones, in charge of designing content for Galvinpower. However, in regard to the second criterion, given that the distance is 150 feet, the rule of thumb mandates the utilization of a wire that is of a greater thickness.
