At a median 75°C temperature, the ampacity of the 0 AWG copper wire is 150A. Accounting for NEC 80% rule, this means that a 0 AWG copper wire can handle up to **120 amps** of current. Depending on the voltage, the 0 AWG copper wire can carry anywhere from 1440 watts (12V circuit) to 28800 watts (240V circuit).

## What gauge wire is best for car audio?

When you replace or run new speaker wiring, we recommend using: **18-, 16-, or 14-gauge wires for speakers**. 16-, 14-, or 12-gauge wires for subwoofers.

## What can 0 gauge wire handle?

At 60°C, it can handle **up to 125 amps, and it can handle up to 170 amps at higher temperatures (90°C)**. 0 gauge wire can be used for a number of different electrical applications. That’s why we also referred to it as: 0 gauge battery cable (for bigger 12V and 24V batteries).

## Is there a 0 AWG wire?

American Wire Gauge (AWG) is the standard way to denote wire size in North America. In AWG, the larger the number, the smaller the wire diameter and thickness. **The largest standard size is 0000 AWG**, and 40 AWG is the smallest standard size.

**How many amps can 0 gauge wire handle? – Related Questions**

## What is 0 gauge wire called?

Tables of AWG wire sizes

AWG | Diameter | Copper wire |
---|

Ampacity at temperature rating |
---|

000 (3/0) | 0.4096 | 165 |

00 (2/0) | 0.3648 | 145 |

**0 (1/0**) | 0.3249 | 125 |

## Is 1 0 and AWG the same?

A: The number in front of the “/” is how many zeros the gauge is. **1/0 is 0 AWG**, 2/0 is 00 AWG, 3/0 is 000 AWG and so on with more zeros being thicker wire.

## Can a wire have zero resistance?

**Points directly connected together in a circuit by zero resistance (wire) are considered to be electrically common**. Electrically common points, with zero resistance between them, will have zero voltage dropped between them, regardless of the magnitude of current (ideally).

## Does earth wire have zero voltage?

**Earth wire is also having zero voltage** similar to the neutral wire, but it accomplishes a very different role.

## How thick is a 0 gauge wire?

0 Gauge Wire Physical Dimensions

The physical dimensions of the solid copper 0 gauge wire are: Diameter: 8.2515 mm, 0.3249 inches, Cross Section: 53.4751 mm^{2}, 0.0829 inches^{2}.

## What is the thinnest AWG wire?

7/0, the largest size, is 0.50 inches (500 mils or 12.7 mm) in diameter (250 000 circular mils in cross-sectional area), and the smallest, **No.** **50**, is 0.001 inches (1 mil or 25.4 μm) in diameter (1 circular mil [cross-sectional area] or 0.7854 millionths of a square inch).

## What is the strongest thinnest wire?

Synopsis. **Graphene** is the strongest, thinnest material known to exist. A form of carbon, it can conduct electricity and heat better than anything else.

## What is bigger 1 0 or 1 AWG?

But looking at the title of this thread, are you referring the difference between #1 AWG and 1/O AWG? There is a difference, **1/O is one wire size larger**.

## Why is thick wire better than thin wire?

The thin wire will conduct electricity, but there is more electrical resistance. The thicker wire is like the four lane highway. **There’s a lot less electrical resistance**, and as a result, that light bulb burns brighter because more electricity can reach it.

## Do thinner wires get hotter?

**The thinner wire gets hot because of the lower volume**. With the same amount of energy going into the wire, it will have a greater increase in temperature.

## What happens if you use too thick wire?

**Excess Voltage drop in the circuit**. The wire will get hot and the insulation will melt and the hot (glowing) wire will cause a fire.

## Does wire size affect amperage?

The larger diameter of the bigger wire offers more area for electrons to move through the circuit. For this reason, **smaller gauge wire is rated for lower amperage (electric current) limits than larger gauge wire**. The smallest size of common household wire can carry 15 amps of current.

## What gauge wire do I need for 1000 watt amp?

Why Use Quality Audio Wire

Amp Kit AWG (Wire Size) | Amplifier Wattage |
---|

**1/0 AWG** | 1000 Watts RMS and up |

4 AWG | 500 – 1000 Watts RMS |

8 AWG | 250 – 500 Watts RMS |

10 AWG | Less Than 250 Watts RMS |

## What gauge wire should I use for 12V?

In practice, we use wires from **16 AWG to as thick as 3/0 AWG** for 12V circuits (size depends on the max. wattage and wire length or voltage drop).

## Does doubling up wires increase amperage?

Using a second cable with identical physical properties (length, cross-sectional area, conductor type & quality, etc.) **theoretically doubles the ampacity**.

## What does too much current do?

**Fuses and circuit breakers open or break the circuit automatically** when too much current flows through them. When that happens, fuses melt and circuit breakers trip the circuit open. Fuses and circuit breakers are designed to protect conductors and equipment.
