What is the size wire for 200 amp?
At least 000 AWG copper or better yet, 0000 AWG copper. Another consideration is how far the 200 Amps are to be carried. Wire has resistance and 0000 copper has a resistance of .04901 Ohms per thousand feet. At 200 Amps, this means that over one thousand feet the voltage will be 9.8 Volts lower than at the starting point.
How far can you run 250 mcm wire rated for 90 c for 200 amp service?
With a 250 MCM copper conductor delivering 200 amps on a 240 volt system, a maximum distance of 278 feet will be allowed. This distance will hold the voltage drop to less than 3 percent.
Can a 15 amp breaker be replaced with a 20 amp?
Please be more specific....simply replacing the breaker with a 20 amp may cause a fire; if the cable is sized for 15 amp and is overloaded. Your 15 amp breaker is probably feeding #14 wire. The use of a 20 amp breaker requires at least a #12 wire be used. Fire hazard if breakers and wiring are not sized correctly.
What wire size should you use for with a 50 amp breaker?
Breakers and wires can not be connected together this way. It is the amperage of the load that govern the wire size.The breaker is then chosen to protect the wire size amperage. It also depends on what the load is. If it is a motor, then the breaker is 250% of the motors full load amperage, even though the wire size remains the correct size to carry the motors full load amperage. A #6 copper conductor with an insulation rating of 90 degrees is rated at 60 amps.
What gauge wire do you need for a 280 foot run to supply your barn from your house panel?
Without knowing what you are planning as far as load (lights,welder, refrigerator, AC,power tools) I would run #3 copper for the ungrounded legs, #6 copper for the grounded conductor(neutral) and #8 copper for the grounding conductor. This would would be on a 100 amp breaker.
What wire do you use for 12v and 35w?
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.

How far can you run 12 AWG wire with 20 amps?
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.

What is the difference between a 4 gauge and 8 gauge amp wiring kit?
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.
What is the amp loss of 350awg thhn at 500ft 480vac 3 phase?
First let's correct a couple of things in your question. The 350 is not an American Wire Gauge number. The American Wire Gauge only goes as far as 4/0 (that's pronounced four aught). After that wire is measured in kcmils. The wire that you want to use has a cross sectional area of 350,000 circular mils. Next, there is no such thing as "amp loss" in a circuit. The ampere value in a circuit is determined by the connected load. You do not give this value so for this calculation I will use a figure of 200 amperes. We now can compute the voltage drop that we will have in the circuit for a 200 amp three phase load. I also assume that you are using copper conductors. The formula that we will use is: VD = 500 X 1.732 X 12.9 X 200 / 350,000 This says that voltage drop is equal to the one way length of the circuit multiplied by the square root of 3 (for three phase) multiplied by the constant for copper (12.9 ohms/mil foot) multiplied by the ampere load of the circuit and then divided by the circular mil area of the conductor. The answer rounds off to 6.4 volts. We then can find the power loss in the circuit by multiplying the voltage drop by the ampere load and again by the square root of 3. This will give us a 2217 watt power loss in the three conductors. If this was a single phase circuit we would multiply the length by 2 instead of 1.732, and the constant for aluminum would be 21.2 ohms/mil foot. These constants are for a circuit operating at 75 degrees C. Note that the source voltage is not needed for these calculations unless you want to know the percent of voltage drop. this would be 6.4 volts divided by 480 volts or about 1.3%.
How many floors are there in far amp plains?
there are 10 floors in amp plains and 9 floors in far amp plains. in the 10th floor of far amp plains, you battle a boss! (i'm not saying who!)

What kind of wire do you use for a 100 amp service?
If you are supplying power to a 100 amp cont. load then 100 x 125% = 125 amp A #3 wire with an insulation factor of 75 and 90 degrees C is rated at 100 and 105 amps respectively. A #1 wire with an insulation factor of 75 and 90 degrees C is rated at 130 and 140 amps respectively.
