6 awg 80 amps
8 awg 50 amps
10 awg 30 amps

What does OFC mean in power wire?

oxygen-free copper
The term OFC (oxygen-free copper) has become abused and is used synonymously with solid or all-copper conductors. In actuality, OFC is a type of solid copper. When molten copper is cast and drawn into a conductor, the process to make an OFC conductor reduces the oxygen content of the wire.

### Is OFC or CCA wire better?

CCA stands for Copper Clad Aluminum, an alternative to the more vaunted OFC (Oxygen Free Copper) cable. On the whole, CCA is a source of continuing controversy, especially among the old-school 12V crowd and car audio purists, given OFC is a far better conductor of power.

How much better is OFC wire?

A PRO to using OFC is that it carries current further with less resistance and less heat through a wire strand no more than 20ft. It has been shown that a 20 ft 1/0 ofc cable carried around 25% more current than the same length of CCA 1/0.

#### Can 8 gauge wire handle 50 amps?

Up to a point, the higher the temperature, the higher the current the wire can handle. An 8-gauge wire can handle a current of 50 amps at a temperature of 90-Celsius or 194-Fahrenheit.

Is pure copper the same as OFC?

The oxygen content for OFC is typically in the range of 40 parts per million (PPM), while normal grade copper is approximately 235 PPM, about six times less. The result is that OFC has approximately 400 grains or crystals per foot, as opposed to 1500, or about four times less.

## How many amps can 1 0 OFC wire handle?

AWG Wire Gauge Chart (1st Chapter)

AWG Number Diameter (inches) Ampacity (at 75°C)
0000 (4/0) AWG 0.4600 in 230 Amp
000 (3/0) AWG 0.4096 in 200 Amp
00 (2/0) AWG 0.3648 in 175 Amp
0 (1/0) AWG 0.3249 in 150 Amp

What is the difference between OFC and tin OFC?

Tinned copper will not tarnish or oxidize like bare copper. Even Oxygen Free Copper (OFC), which is copper that has been refined to a purity of at least 99.95%, over time when exposed to the elements will tarnish.

### Is OFC speaker wire worth it?

There are different standards of “OFC”. In any case, OFC or regular copper wire are both a lot better than copper-clad or pure aluminum. It’s often recommended to buy a gauge larger if you’re going with CCA over OFC, but you should just go with OFC wire instead.
