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 gauge wire do you run between a 30 amp breaker and an outlet?
10 AWG.
What size wire for 72 amp motor?
You will need AWG #3 if it is a short run.
What size wire is needed for 6.3 amps 240 volts 50 foot run?
14 AWG is fine for this application.

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.
Can you run two 60 amp sources in parallel to get 100 amps out?
No they can not, because the electrical code states that wires in parallel can only be 1/0 AWG and larger. The ampacity of 1/0 wire is 150 amps. The ampacity of a wire for 60 amps is #6 which is much smaller that 1/0 wire.
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.
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?
i personally would run a 10awg wire for anything more than a few feet from the panelboard. when i wire i use some simple calculation to figure out wire size. First Watts(2000) divided by Volts(120) gives you amperage(16.6666). Once you know amperage you can figure out wire size. when figuring out wire size remember that you never want to load over 80% of the wire capacity so 14awg is 15amps but you only load to 12 amps. 12 awg is 20 amps so loaded to 80% would be 16 amps. and 10 awg is 30 amps so loaded to 80% is 24amps. so like I sadi for that circuit unless it is right near the panel i would run 10 awg and probably fuse it at 20 amps.
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.
