The distance that a 6 gauge wire can carry 50 amps depends on factors like voltage drop and wire insulation. In general, a 6 gauge wire can carry 50 amps for up to 60-70 feet without significant voltage drop. However, it is recommended to consult with a professional electrician for accurate calculations and safety considerations.
The maximum distance a 12 gauge electrical wire can run depends on the voltage and amperage of the circuit it is serving. In a typical residential circuit with 120 volts and 20 amperes, a 12 gauge wire can run up to 60 feet before voltage drop and overheating become concerns. It is always best to consult local electrical codes and standards for specific guidance on wire length limitations.
Far as I know it's just size of wire, smaller the gauge the thicker the wire. which means the 4 is going to be thicker than the 8.
Depends on how far you want to carry that load.For short distances, 6 AWG THHN rated at 90C, used at 30C ambient, is permitted for up to 75 Amps when in a 3-conductor cable or conduit.In free air, it may be "capable" of handling up to 105 amps.NEC Table 310.16 and 310.17.
You would need to know how FAR the load is from the service point. Then use an online calculator or the voltage-drop formula to determine the minimum diameter of the conductors necessary to provide 95 percent of the supply voltage to the device at the other end. <<>> If distance is not a factor, the wire size is determined by the amperage the wire has to carry. Using the formula I = W/E, Amps = Watts/Volts = 3000/380 = 7.98 amps. A #14 copper conductor with an insulation factor of 75 or 90 degrees C is rated at 15 amps. This size wire has nearly double the capacity that you need.
The wire to use would be one that can handle the 3 amp capacity of the load. If the load is a long ways away increase the wire size. A #14 wire has the capacity to handle 15 amps. Depends on how far you're running it and what voltage drop you can tolerate. I would use 14 gauge, minimum. That will give less than 10% voltage drop on a copper pair running 50 feet.
As far as I know there is no -33 gage wire. If you meant + then that would be the thinnest so 0 is the answer
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.
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.

A 14 gauge extension cord can safely carry 15 amps, but not very far. Number 14 gauge extension cords are only rated for about 13 amps according to the labels on the cord. This is because the insulation is not intended to withstand the heat of currents above this level. Running this cord over 50 feet or loading it to 18 amps would be unacceptable.The likelihood of the cord maintaining the 18 amps for any amount of time for the high current to do any damage to the insulation of the cord is not very great. Extension cords are only an extension of the 15 amp wall circuit that they are plugged into. On overloading the extension cord by that amount the overload will trip the 15 amp supply breaker. An example of this is jamming a circular handsaw when it is plugged into the end of a 50 foot extension cord. The next action that is taken is to reset the tripped breaker.
Mtx makes the best amps true to power as far as watts go
