A 4500 Watt element typically draws 18. 75 Amps when configured with 240 Volt power. The actual Amp draw will vary slightly based on the actual power supplied, and any additional resistance between the element and power source.

The current can be calculated using Ohm’s law (I = V/R), where I = Current, V = Voltage, and R = Resistance. It is important to match the Watt rating of the element with the power supply (voltage and amperage) to ensure it is safe and not overworked.

Failure to do so can result in reduced life of the element, or even a fire hazard.

## How many amps will a 4500 watt 240V water heater element pull?

The amount of amps a 4500 watt 240V water heater element would pull would depend on the wattage rating of the particular element that you have. Generally speaking, these types of elements are typically rated between 20 and 50 amperes.

To find the exact ampere draw, you will need to look up the specific product’s wattage rating and divide it by the voltage of the element (240V). For example, if the 4500 watt element has a wattage rating of 50 amperes, it would pull 4500 / 240 = 18.

75 amperes, rounded up to 19 amperes.

## Will a 4500 watt water heater work with a 20 amp breaker?

Yes, a 4,500 watt water heater can work with a 20 amp breaker. Many water heaters will come with a breaker sized for the wattage of the heating element, so it’s important to make sure the breaker size is appropriate for the heater.

A 4,500-watt heater with an element rated at 20 amps would require a 20-amp breaker. This means that a 20-amp breaker would provide the necessary protection against potential electrical overloads. When selecting an appropriate breaker size, it’s important to remember that the wattage rating of the heater should be multiplied by the voltage of the circuit to determine the necessary breaker size.

In this case, a 4,500 watt element multiplied by the typical circuit voltage of 240 volts would mean that the breaker size should be at least 20 amps.

## How many watts will a 20 amp circuit breaker handle?

A 20 amp circuit breaker can handle up to 2400 watts of power. This is determined by multiplying the amperage (20A) by the standard household voltage of 120V. This means that a circuit protected by a 20 amp breaker is capable of handling a maximum of 2400 watts of power.

It is important to note, however, that this maximum wattage should not be exceeded, as doing so can potentially overload the circuit and cause a fire hazard. Additionally, for any circuit, it is important to ensure that the wattage of the items connected to the circuit does not exceed the maximum capacity for the circuit.

## Is 25 amp breaker enough for water heater?

Additionally, if the water heater is being used often or drawing hot water from multiple fixtures, the time to heat the tank will be longer.

## Can I use 10 2 wire for a hot water heater?

Yes, you can use 10-2 wire for a hot water heater, but whether it is the best choice for your specific application depends on a number of factors. When wiring an electrical device such as a hot water heater, the size of the wire must match or exceed the amount of current that the device draws.

This is typically listed on an information plate located on the device or in the documentation that came with it. 10-2 wire is rated for 30 amps, which is sufficient for many hot water heaters, but if the current needed is greater than that you may need to use a larger wire size like 8-2.

In addition to the size of the wire, the distance to the circuit breaker and the size of the circuit breaker must also be considered. It is recommended to have a 20 amp circuit breaker on the main panel and a dedicated circuit breaker at the hot water heater location, both of which should be sized appropriately for the current draw of the hot water heater.

In short, if all the conditions are right, then 10-2 wire is suitable for a hot water heater, however, it is important to check the current draw of the device and choose an appropriate wire size to avoid potential hazards.

## How many heaters can you run on a 30 amp breaker?

It is difficult to say how many heaters can be run on a 30 amp breaker, as it depends on the size and wattage of the heaters. Generally speaking, it is recommended to not draw more than 80 percent of the breaker’s capacity, which in this case is 24 amps.

It is important to remember that all appliances draw different amounts of amperage. The best practice is to calculate the total wattage for all appliances being used on the circuit, and then divide it by the voltage of the circuit (which is usually 120).

That would give you the total amps for all appliances being used on the circuit. If the total amps don’t exceed 24 amps, it is safe to install the circuit. It is also advised to have a qualified electrician check the wiring if unsure.

## Are all 30 amp breakers the same?

No, not all 30 amp breakers are the same. Each of which is designed to handle a specific type of load. Some of the most common types of 30 amp breakers are single-pole, double-pole, GFCI, AFCI, and Arc Fault Circuit Interrupting (AFCI) breakers.

Single-pole breakers are often used to power light fixtures, while double-pole breakers are used to divide 240-volt circuits. GFCI breakers are designed to protect against ground fault circuit interruptions, while AFCI breakers protect against arc fault interruptions.

Arc Fault Circuit Interrupting (AFCI) breakers are designed to stop a dangerous feedback of electrical current, which can trigger a fire. All of these breakers have a maximum 30-amp rating, but they are designed for use with different loads and hazards.

As a result, it’s important to choose a breaker that is appropriate for the specific task at hand.

## Do electric water heaters use a lot of electricity?

Electric water heaters usually use a significant amount of electricity. Depending on the size of the unit and the amount of water it needs to heat, the amount of electricity it consumes can vary.
