Typically you don't want more than a 10% drop in voltage. If it were a 120 VAC circuit that would be a drop of 12 volts. At 20 Amps that is a resistance of .6 ohms. That is about 380 feet.
Allowing for a 10% drop in voltage would allow you to run 20 amps on 12 gauge copper to 151 feet.
Also, the NEC suggests, but does not require, that voltage drop be limited to 3% on branch circuits. In the field this is treated by most electricians as an absolute requirement, not a suggestion. This allows you to run a 20 amp load to only 45 feet on 12 gauge wire. Notice that voltage drop is calculated based on connected load, not the rating of the circuit. A 20 amp load would be connected to a 25 amp or 30 amp circuit, requiring larger wire and allowing for longer distance.
In a home a 30 amp circuit would most likely be 240v and would require #10 gauge conductors. Using these numbers to calculate a 3% voltage drop allows you to run this circuit 145 feet. At 120v on #10 gauge wire a 20 amp load can be run just over 72 feet.

How many amps is 3 awg wire good for?
It depends on the application, but for Single-Phase dwelling service and feeders 3 AWG copper is good for 110 amps. That really equates to 100 amps since you can't get a 110 amp circuit breaker.
What is the amp size of 10 awg wire?
A 10 AWG wire is typically only rated for 30 amps, but conditions such as length of run, whether the wire is to be used in a "plenum", temperature and other factors may affect the type of wire that you must use for a specific application. If you have any questions, contact a qualified electrician or your local building inspector.
What about distance of 14 gauge wire?
It depends on the load applied. With a load of 10 amps you would loose 5 volts at 100 feet. I would not run it over 50'. This is one of the reasons I never wire any home with AWG#14 wire even though you can use it in bedrooms. I prefer to use AWG #12.
What size wire for 72 amp motor?
You will need AWG #3 if it is a short run.
What gauge wire do you run between a 30 amp breaker and an outlet?
10 AWG.

How far can you run 10 AWG with 30 amps?
This is a voltage drop question. The circuit's voltage must be stated to answer this question.

What size wire do you need to run to an air conditioner that has a maximum breaker size of 40 amps and a minimum circuit size of 25.3 amps?
You would need to use a wire size that is rated for at least 40 amps to be safe and to meet the requirements of the air conditioner. A common wire size for this application would be 8 AWG copper wire, which is rated for 40 amps.
How does length of run affect the wire gauge to be used?
The longer the run, the bigger and heavier the wire will need to be. The AWG number denotes the diameter of the wire: the smaller the AWG number, the bigger the diameter.
What minimum size of AWG do you need to connect a 120 Volt branch circuit that supplies a total power of 2000 Watts?
For a 120V circuit with 2000 Watts, the current can be calculated using the formula P=IV, where P is power in Watts, I is current in Amperes, and V is voltage in Volts. So, I = 2000W / 120V = 16.67A. To determine the minimum wire size, refer to the American Wire Gauge (AWG) chart to find the closest AWG size that can safely carry 16.67A without exceeding its ampacity. In this case, a 14 AWG wire can handle 15A comfortably, so a 12 AWG wire would be suitable for this application.
Can you use 16 gauge wire for 240?
No, you will need a minimum of at least AWG #12 and you may need even bigger depending on the Amps required to run whatever you are using.
What about distance of 14 gauge wire?
It depends on the load applied. With a load of 10 amps you would loose 5 volts at 100 feet. I would not run it over 50'. This is one of the reasons I never wire any home with AWG#14 wire even though you can use it in bedrooms. I prefer to use AWG #12.
Would a 1.5 mil cable have enough capacity to run a 500 watt sensor light?
Yes, there will be enough capacity to run a 500 watt sensor light. Assuming by the wire size, the question is from a 50 Hz country where the operating voltage is 240 volts. Amps = Watts/Volts = 500/240 = 2.08 amps. The ampacity of a 1.5 mil conductor is 15 amps. This size wire is equal to a #14 wire AWG.
What size cable for hundred and twenty meter run for hundred and twenty amps?
# 2-awg
how far can you run 10 wire for 1500 watt 20 amps?
That is a voltage of 75 v. The distance is calculated by allowing a 5% voltage drop in the resistance of the wire, or 3.75 v. With 20 amps and a voltage drop of 3.75 volts the allowed wire resistance is 0.1875 ohms. 10-AWG wire has a resistance of 1 ohm per 1000 ft, so the total length of wire allowed is 188 ft. Assuming 2 wires the allowable distance is 94 ft.
Can you run two 60 amp sources in parallel to get 100 amps out?
No, you cannot run two 60 amp sources in parallel to get 100 amps out because each source will still provide a maximum of 60 amps. When you connect them in parallel, the total current output will remain the same as the output of a single source, which is 60 amps in this case.
