## How do I calculate what size wire I need?

Wire Sizing Chart and Formula

1. Calculate the Voltage Drop Index (VDI) using the following formula:
2. VDI = AMPS x FEET ÷ (% VOLT DROP x VOLTAGE)
3. Determine the appropriate wire size from the chart below.

## What size wire do I need for 1500 watts?

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

## How many watts can 22 gauge wire handle?

If the wire is used to make an antenna where applied power is supposed to radiate and not be dissipated, 22 AWG copper wire easily handles 1500W applied RF power.

## What size power wire do I need for a 1000 watt amp?

If your amp is capable of 1000 watts RMS then it requires 4 gauge wire.

## What happens if amp power wire is too small?

If too small of a size is used, the wire could melt because of the large amount of current flowing through it compared to how much the cables can handle. Damage can occur to the amplifier when there is not enough current flowing to its circuits, especially when the music peaks.

## What gauge wire should I use to connect AMP?

which is the most common connection

• 25 for a copper wire with an ambient temperature rating of 75 ℃ or 167 ℉
• 30 for a copper wire with an ambient temperature rating of 90 ℃ or 194 ℉
• 20 for an aluminum wire with an ambient temperature rating of 75 ℃ or 167 ℉
• ## What size wire do you need for a 20 amp?

For a 20 amp circuit, use 12 gauge wire. For a 15 amp circuit, you can use 14 gauge wire (in most locales). For a long run, though, you should use the next larger size wire, to avoid voltage drops. 12 gauge is only slightly more expensive than 14 gauge, though it’s stiffer and harder to work with.

## What is the correct size wire for 60 amp service?

Size of wire for 60 amps should be minimum 6 square mm. #6 AWG should do the trick. It will though, also depend on the wire insulation, distance to the panel and also the duty cycle of the appliance.

## What gauge wire is needed for 30 amps?

A 30 amp circuit requires a number 10 (10 gauge) wire. Most 30 amp circuits are 220 volt so you will need 10/3 with ground cable to power these. That means there will be 4 wires total in the cable.
