How many amps can a 1/0 wire handle?
At 75°C, the 1/0 copper wire ampacity is 150 amps; essentially, the 1/0 W wire is a 150 amp wire size. At 60°C, it can handle up to 125 amps, and it can handle up to 170 amps at higher temperatures (90°C).
How many amps does a 2 gauge wire handle?
Well, at standard temperature of 75°C, the 2 gauge wire has a 115 amps ampacity. That means that any 2 gauge copper wire can, at that temperature, handle up to 115 amps safely. There are a number of cables that contain the 2 gauge wire, including:
Can 8 gauge wire handle 50 amps?
For everybody wondering if the 8 AWG wire can handle 50 amps, here is the answer: The ampacity of the 8 gauge wire is exactly 50 amps at 75°C. That means that 8 gauge wire can indeed carry 50 amps at 220-volts. That gives it quite a few applications. 8 gauge wires are used as:
What gauge wire should I use for 30 amps?
For 30 amps, the 12 gauge wire (with 35 amp rated ampacity) is a better choice. For the 20 amp circuit, on the other hand, the 14 gauge wire would be an optimal choice. 10 gauge wire is rather cheap per foot. iGreely, for example, offers 8 gauge wires for $1 to $5 per foot (longer 10 gauge wires are cheaper per foot):

What wire size do I need to go 100 feet for a 60 amp service to a workshop?
What size wire should I use for a 60 amp subpanel? You can get away with 6 AWG when you have a short run of wire, however, due to voltage drop, if you ever decide you want to go more than 100 feet then a 4 AWG is the size you should choose.
What size wire do I need for 50 amps at 100 feet?
6 AWGFor every 100 feet, voltage drops by 20%. Example: 50 amp wire is usually the 6 AWG (we require at least 62.5A and 6 AWG can handle 65A). If you have to power an electric device 100 feet away, you need 20% amps more. Instead of 62.5A, you're looking at 62.5A × 1.2 = 75A.
How far can you run a 220 line?
1 conductors per phase utilizing a #8 Copper conductor will limit the voltage drop to 4.35% or less when supplying 20.0 amps for 400 feet on a 220 volt system.
Can you run a 200 amp sub panel off 200 amp main?
Is feeding a 200A sub from a 200A main legit? Yes, and you don't even need another 200A breaker. The 200A breaker alread present in the panel will suffice, and so you can use a subfeed lug kit as DrSparks advises.
What size wire do I need to run 100 amp Service 150 feet?
#00 AWG wireWire Size For 100 Amp Sub Panel 150 Feet Away 100 amp service 150 feet away from the sub panel requires #00 AWG wire (also known as 2/0 AWG wire). This wire has a median ampacity of 175 amps; more than enough than the required minimum 162.5 ampacity.
What size wire do I need for a 100 amp underground 300 ft run?
for 300 feet for 100 amp rated service I would use Aluminum direct burial 1/0-1/0-1/0-1/0, the forth can be as low as #4 for the ground (but also in conduit, even if in conduit must still be rated underground wire and required by code also) Also note the size wire the breaker can handle, cannot cut strands to make fit, ...
How many amps does a car electrical wire need?
For example, you want to add some flood lights to your vehicle. The floodlights draw 15 amps of current. The length the wire needs to be to connect to the floodlights is 9 ft. Based on the chart above, you would want to use 12 gauge automotive wire for your floodlights.
How many watts does a 20 amp wire absorb?
If you are running 20 amps through your wire then your wire is absorbing 4.8 watts of power. Now let’s say your wire has a 20% voltage drop. The voltage reading on your volt meter at the end of the wire will only be 9.6 volts, and the wire is absorbing a whopping 48 watts of power!
How many volts does a battery cable use?
At the source, or battery, you will read 12 volts using a voltage meter, but at the other end of the cable your voltmeter will only read 11.76 volts (12 volts -2%). If your circuit needs 100 amps of current, the battery cable will absorb 24 watts of power because of it’s resistance.
Why is the size of an automotive wire important?
Why is the size of an automotive wire so important? When electricity passes through a wire, The wire resists the electricity and some of it is converted into heat that is absorbed by the wire. This lost energy is realized in the form of a voltage drop at the end of the wire.
How many amps does a floodlight draw?
The floodlights draw 15 amps of current. The length the wire needs to be to connect to the floodlights is 9 ft. Based on the chart above, you would want to use 12 gauge automotive wire for your floodlights.
How far back does a negative cable go from a battery to a battery?
So if you have a 10 foot run from your battery, you actually have a total of a 20 foot run because the negative cable will also be 10 feet back to the battery.
Can you pull copper wires apart?
Basically, if you crimp your wire and terminal together, and you cannot pull them apart, the connection will most likely suffice.
How to choose wire gauge?
To choose an adequate wire gauge, determine the amp draw (amperage) that the wire circuit will carry. Then measure the distance that the wire will travel (length) including the length of the return to ground (the ground wire running to the chassis or back to a ground block or battery. Using these two numbers, Amps and length, ...
Why is it important to factor in the length of wire when determining the gauge of a wire?
All wire has inherent resistance and the longer the wire, the greater the resistance and the greater the voltage drop over the length of wire. For that reason, it is important to factor in the length of wire when determining the wire gauge.
What is SWG gauge?
SWG and AWG are wire gauge systems used to represent the thickness of the wire. Different numbering systems are used depending on the type of metal. Non-ferrous metals (not containing iron) use American Wire Gauge System or AWG. Ferrous metals generally use Standard Wire Gauge (SWG). Also see:
How many volts does an alternator give?
When the vehicle is running, the alternator will increase the automotive voltage up to about 13.8 volts. 13.8 volts is a better value to use for wire gauge calculations though it will generally result in about the same gauge as 12 volts.
What is the difference between a 3 foot wire and a 20 foot wire?
A 3-foot wire length will have less resistance than a 20- foot wire and therefore a longer length of wire may require an increase in the wire gauge to provide adequate voltage to the accessory. Installing too small a wire gauge decreases performance and may create a potential safety hazard.
How many volts does a 6 cell battery have?
The actual resting voltage of a fully charged, 6-cell automotive lead acid battery is about 12.7 volts or about 2.1 volts per cell. 6.4 volts for a 6-volt lead-acid battery. Older batteries will probably show a lower voltage. When the vehicle is running, the alternator will increase the automotive voltage up to about 13.8 volts.
