To calculate the amperage, use the formula: Amps = Watts / Volts. In this case, it would be 2400 watts / 240 volts = 10 amps. Therefore, the water heater would draw 10 amps of current.

May 240 30 amp water heater be plugged into three prong drier receptacle?

It's not recommended to plug a 240V 30 amp water heater into a 3-prong dryer receptacle. Dryer outlets are typically 240V with a different configuration that may not be compatible with the water heater. It's best to have a qualified electrician install the appropriate outlet for your water heater to ensure safety and functionality.


How do you change a heater from 120 volts 3a to 240 volts 1.5 a?

the simplest solution is by connecting two 120v 3amps heater in series , the same can be used directly on 240v. However the current drawn will still be 3 amps & Not 1.5 amps. The heater output power will be double that of a single heater running on 120v. ( or equvalent to two heaters operating on 120v. supply ) A more expensive method is to use a stepdown transformer which can be powered on 240v & connect the heater on the transformer 120v side. this method will consume approx. 1.5 amps from the 240v supply.


Will 240v heater work with 220v output?

Yes, a 240v heater will work with a 220v output. The slight difference in voltage should not significantly affect the heater's performance. However, it is always recommended to check the manufacturer's specifications to ensure compatibility.


What is the breaker size for a 10 KVA electric heater?

The breaker size for a 10 KVA electric heater would depend on the voltage it operates at. For example, for a 240V heater, you would need a 41.67 Amp breaker (10,000 VA / 240V = 41.67 A). It is important to consult with a licensed electrician to ensure the correct breaker size and electrical setup for your specific heater.


How do you calculate the current for single phase water heater?

To calculate the current for a single-phase water heater, you can use the formula: Current (A) = Power (W) / Voltage (V). Determine the power rating of the water heater in watts and the voltage it operates at (usually 120V or 240V in residential settings), then divide the power by the voltage to find the current in amperes (A).

Can you use one wire from the panel with 240v on it to wire a 240v water heater?

In North America it takes two "hot" wires to obtain 240 volts.

A 208V water heater can te be replaced by a 240V water heater?

Yes but you will not get the full watt rating out of the tank. Watts = amps x volts. Say the tank draws 20 amps. 20A x 240V = 4800 watts. 20A x 208V = 4160 watts. It will take longer to heat your water with less wattage.


You are building a new house and trying to decide between 120v and 240v which is better More practical?

In the US, both 120v and 240v will be needed for your home, as different appliances need different voltages. Your TV needs 120V, while your electric dryer and stove will need a 120V/240V supply. If you have an electric water heater, or central AC unit, they will need a 240V supply.

IS there an adapter for a 240V heater that will allow you to plug it into two 110V outlets?

No. Sounds like a fairly hazardous thing to try as well. If it's to use a heater in the US, then buy a US heater at a lower cost than any adaptor that might do the job for you. If it's to use on a UK building site that has 110V but doesn't have 240V, it breaks all the rules because you end up with 240V where you shouldn't.

How can you get 240V single phase power from a 240V 3 phase service Can you just connect to two poles of the 240V 3 phase service?

I'm sure this isn't what you want to hear, but you probably need to ask an electrician familiar with your service and what you want to connect. As a general answer, you can connect a 240v line to line resistive load like an electric water heater to any 240v source. If you also need the 240v to have 120v line to neutral, like a 240v electric stove that contains a 120v clock and oven light, then its possible if the 3 phase power is connected in a "high delta" configuration, and you connect to the correct leads. If you have a high delta service and want to ignore the 3-phase power service and wire most or all of the loads in the building as a single phase load, the utility may have to be consulted.
