FAQ: How many watts can 4 gauge wire handle?

What Gauge Wire Do I Need For My Amp?

Wire Gauge Size Total Amplifier RMS Wattage
2 AWG 1000-1500 Watts
4 AWG 400-1000 Watts
6 AWG 600-800 Watts
8 AWG 200-400 Watts
  • A basic rule of thumb is this. For up to 500 watts RMS, 8 gauge is sufficient. In the 500 – 1000 watt RMS range, you want to run 4 gauge. From 1000 – 1500 watts RMS you should be running 2 gauge.

How many amps can 4 gauge wire handle?

Common sizes include 14-, 12-, 10-, 8-, 6-, and 2-gauge wire.

How Wires Are Sized.

Amperage Capacities for Standard Non-Metallic (NM) Cable
8-gauge wire 40 amps
6-gauge wire 55 amps
4gauge wire 70 amps
3-gauge wire 85 amps

What gauge wire should I use for a 2000 watt amp?

So, for a 2000 watt amp going by most charts you will need between 4 gauge wire to 00 gauge wire depending on how far you are going. If you are only going 0-4 feet that is when you can get away with the smaller wire, but anything beyond that you will need thicker wire. 2 gauge can be used for 4 feet to 10 feet.

What is 4 AWG wire used for?

4 AWG THHN-THWN-2 is permitted for new construction or rewiring for 600-volt applications. Applications requiring Type THHN or THWN-2, the conductor is appropriate for use in wet or dry locations at temperatures not to exceed 90°C or not to exceed 75°C in oil or coolants.

What gauge wire can handle 50 amps?

For a maximum of 50 amps, you’ll need a wire gauge of 6. Fifty amp breakers are most often used to power many different appliances.

What happens if wire gauge is too big?

using larger wire will not hurt anything or cause any overload. The larger wire will cost more, the pathway or where it has to fit, and the physical size of the connecting means (ie. the size of terminal or clamp it has to fit in), will all be determining factors in just how big is too big.

Does stranded wire carry more current?

Because of the given thickness of stranded wire, i.e., it’s thinner, there are more air gaps and a greater surface area in the individual strands of wire. Therefore, it carries less current than similar solid wires can.

How many amps is 1000 watts?

Watts To Amps Table (At 120V)

Watts: Amps (at 120V):
700 Watts to amps 5.83 Amps
800 Watts to amps 6.67 Amps
900 Watts to amps 7.50 Amps
1000 Watts to amps 8.33 Amps

Is 14 gauge speaker wire good for subs?

As mentioned already, subwoofers typically use lower gauge wire. The most common speaker wire gauges for subwoofers are 16, 14, and 12. When choosing a gauge, it is better to round up than to round down in size. Using an 18 gauge wire when you need a 14 gauge wire will result in poor performance from your subwoofer.

Is 8 gauge wire enough for 1000 watts?

A basic rule of thumb is this. For up to 500 watts RMS, 8 gauge is sufficient. In the 500 – 1000 watt RMS range, you want to run 4 gauge. From 1000 – 1500 watts RMS you should be running 2 gauge.

Will 8 gauge wire carry 50 amps?

8 AWG may carry a maximum of 70 Amps in free air, or 50 Amps as part of a 3 conductor cable.

Can I use 8 gauge wire on a 20 amp circuit?

RULES OF THUMB

“Twelve-gauge wire is good for 20 amps, 10-gauge wire is good for 30 amps, 8gauge is good for 40 amps, and 6-gauge is good for 55 amps,” and “The circuit breaker or fuse is always sized to protect the conductor [wire].”

What wire size do I need to go 100 feet for a 60 amp service to a workshop?

For 60 amps #6 wire is the right size. Use RHW or THHN type insulation.
