You should have proper knowledge about the wattage that a particular amps breaker can handle. There will be a lot of problems if you can’t handle the circuit load so this article will guide you about how many watts can a 30 amps breaker handle and how to convert amps to watts.

## How many watts can a 30 amps breaker handle?

- On average a 30 amps breaker with a 120-volt circuit is able to handle 3600 watts of load.
- A 30 amps breaker with a 240-volt circuit can handle a 7200-watt rating.

The wattage that a 30 amps breaker circuit can handle depends on voltage. You can get to know yourself by a formula that you will read next

## How to calculate 30 amps to volts?

To calculate what volts a circuit need with 30 amps breaker follow the step

**you have to divide the wattage by the amperage**. For example,

If it has 30 amps and 3600 watts and to calculate the voltage, divide the wattage by amperage:

**Voltage = wattage ÷ amperage**

Volt= 3600 ÷ 30 = 120 volt

Similarly, if it has 30 amps and 7200 watts then the voltage is:

Volt = 7200 ÷ 30 = 240 volts.

**Note:**

**Every electronic device uses ampere, volts, and watts, in its specifications sheet whether it is an air conditioner or a Washing machine these three are considered the basic unit of electricity.**

Next, I have explained how to convert amps to watts using a formula.

## Formula to convert amps to watts:

To calculate the wattage of a circuit we need to have the amount of amperage and voltage.

**Watts = amps × volts**

To learn the conversion you should know a few calculations.

## How many amps are there in a watt?

To calculate the watts we need to know the voltage let’s assume the basic voltage of 120V now using the formula:

P = 1 A × 120 V = 120 watts. So here it is clear that at 120V, 1 amp has 120 watts.

If we considered the voltage of 220V then.

P = 1 A × 220 V = 220 watts. Here we find that 1 amp has 220 watts at 220 volts.

The following table shows full amps to watts conversion:

How many watts in 40 amps? | 4800 watts | 8800 watts |

How many watts in 50 amps? | 6000 watts | 11000 watts |

How many watts in 60 amps? | 7200 watts | 13200 watts |

How many watts in 70 amps? | 8400 watts | 15400 watts |

How many watts in 80 amps? | 9600 watts | 17600 watts |

How many watts in 90 amps? | 10800 watts | 19800 watts |

How many watts in 100 amps? | 12000 watts | 22000 watts |

How many watts in 150 amps? | 18000 watts | 33000 watts |

How many watts in 200 amps? | 24000 watts | 44000 watts |

**Let’s understand it by example:**

- To convert 3 amps to watts that are connected to 120 Volts we can find the answer easily by looking at the chart above and also calculate it by using the formula:

**Watts = amps × volts**

Watts = 120 × 3 = 360 watts.

- To convert 15 amps to watts which are connected to 120 volts.

By using the formula, Watts = amps × volts

Watts = 120 × 15 = 1800 watts.

- To convert 150 amps to watts which are connected to 120 volts.

By using the formula, Watts = amps × volts

Watts = 150 × 120 = 18000 watts.

## Conclusion:

In the end, we can say that to convert the amps to the wattage you need to know the voltage, and using the formula you can easily convert it. Also to know how many watts can a 30 amp breaker handle depending upon the voltage, use the formula that it mentioned above.

## FAQ’s

### How many things can you connect to a 15 amps breaker?

Consider 15 amps to 12 amps then use the appliances as many as you want until they pull more than 12 amps.

### What is the cause of overload?

Overloading of the circuit happens when the total appliance load exceeds.
