What size wire do I need for 4 amps?
Maximum current (amps) in a 12V electrical circuit vs. size (AWG) and length of wire.
| American Wire Gauge (#AWG) | ||
|---|---|---|
| Length (feet) | Maximum Current (amps) | |
| 20 | 14 | 6 |
| 25 | 14 | 4 |
| 30 | 12 | 4 |
How many amps can 8 copper carry?
#8 Gauge THHN Copper Stranded Wire is the most popular single conductor copper wire we carry and is RATED FOR 55 AMPS @ 90°C.
How thick wire do I need?
To determine what gauge wire you need, consider the carrying capacity and the amount of current the wire needs to conduct (measured in amperage or amps). Wire gauge is directly related to how many amps you need to run through it. The distance you need the wire to go can also impact the gauge of wire you need.
How many amps will #4 copper wire carry?

How thick is a 4 gauge wire?
Gauge Thickness chart & Information:
| Gauge -Thickness | Dimension inches thick | Dimension millimeters thick |
|---|---|---|
| 4 | .204 inch | 5.189 mm |
| 6 | .162 inch | 4.1mm |

| 9 | .114 inch | 2.91 mm |
What is 22 gauge copper wire used for?
Here at SparkFun, we typically use 22 AWG wire for prototyping and breadboarding. When using a breadboard or PCB, solid core is perfect because it fits nicely into the holes. For other prototyping/building involving soldering, the stranded core is #1, just be sure not to let too much current run through a single wire.
What minimum size copper equipment grounding conductor is required for a 400 amp feeder?
MIN. SIZE OF EQUIPMENT GROUNDING CONDUCTORS (EGC) for Grounding Raceway & Equipment
| Rating or setting of Automatic Overcurrent Device (OCPD) in Circuit ahead of Equipment [i.e Circuit Breaker]. Not exceeding (Amps) | Size (AWG or kcmil) | |
|---|---|---|
| 200 | 6 | 4 |
| 300 | 4 | 2 |
| 400 | 3 | 1 |
| 500 | 2 | 1/0 |
What is the thickness of copper wiring used in the home?
The thickness of copper wiring used in the home will depend on the load it has to carry. Copper wires are specified in the SWG, depending on the diameter of the wire or in terms of sq. mm, which all depends on the area of the cross section of the wire.
What wire thickness do I need to transport 3 amps?
To transport 3 Amps over 2m you need a minimal wire thickness of 0.75mm2 or between 22 and 20 gauge To transport 3 Amps over 10m you need a minimal wire thickness of 1.5mm2 or between 16 and 14 gauge
What is the minimum wire thickness for analog white LED strip?
For hooking up analog white LED strip the + and – wire need to be the same thickness. To transport 7 Amps over 2m you need a minimal wire thickness of 1.5mm2 or between 16 and 14 gauge To transport 3 Amps over 2m you need a minimal wire thickness of 0.75mm2 or between 22 and 20 gauge
What gauge wire do I need to run a 12V to 24V?
Going by what this table says for 12v 8Amps you need a 14 gauge cable. If you where to buy everything 24v you’d only need to transport ~4Amps of power and thus only need a 22 to 20 gauge cable.
