**What size breaker do I need for 240 volts?**

According to the National Electric Code heating circuits are considered a continuous load and therefore must be derated by 25%. (For example: a 20 Amp heating circuit cannot have more than 16 Amps of load connected.) 120 Volt heaters require 1-Pole circuit breakers; 240 Volt heaters need **2-Pole breakers**.

**How far can you run 8-gauge wire for 30 amps?**

10-gauge wire is usually used for short 30 amp runs. If you plan on going **over 150 feet**, 8-gauge wire or thicker will be needed.

**Will a 12 2 wire carry 30 amps?**

If you look in the code book, 12 AWG wire **is legal to 30 amps** if you can run it at 90 degrees C.

**What size wire can handle 30 amps?**

For a maximum of 30 amps, you’ll need a **wire gauge of 10**. The most common household item that requires a 30 amp circuit is a central air conditioner.

**What is 30 amps in Watts?**

The formula is 30 amps X 120 volts = **3,600 watts**.

**How do I convert watts to amps?**

To convert watts (electrical power) to amps (electrical current) at a fixed voltage, you can use a variation of Watt’s Law formula: Power = Current Ã— Voltage (P = IV). By working backwards, we get the equation: **amps = watts Ã· volts**, which can be used to convert watts to amps.

**Can 12 2 be used for 240 volts?**

**Yes**, it is possible to carry a 2000w 240V load on a 12/2 NM-B cable like this one. No, it will not pass an electrical inspection. … I have used 12/2 to feed a 240V circuit – I fed the cable from a 240V 20A circuit breaker and used a red felt-tip permanent marker to color the white wire.

**What kind of Romex do I need for 220?**

**No such thing a 220 Romex** in the US. They do have 240 volt Romex in Canada but it is not what you have drawn. In Canada under CEC a 240 volt only supply use a Romex cable with red and black with ground but no white. No distinction is made in the USA code.

**How many watts will 12 gauge wire carry?**

12 gauge wire is rated for 20 amps peak, 16 amps sustained. On a 120 volt circuit, 120 * 16 = **1920 watts**. On a 240 volt circuit, 240 * 16 = 3840 watts.

**What size wire is needed for a 50 amp sub panel?**

For example, **6-3G cable** is designed for 50 amps when the length of wire does not exceed 55 feet. Beyond that length, a thicker wire is required, due to the voltage drop.

**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.

**What kind of wire do I need for a 50 amp welder?**

A 50-amp circuit breaker and **6-gauge wiring** is required for welders with 40 to 50-input Amps. Smaller welders can use a 10-gauge wire with a 30-amp circuit breaker.

**How do I convert watts into amps?**

To convert watts (electrical power) to amps (electrical current) at a fixed voltage, you can use a variation of Watt’s Law formula: **Power = Current Ã— Voltage (P = IV)**. By working backwards, we get the equation: amps = watts Ã· volts, which can be used to convert watts to amps.
