The power rating and voltage for the pump will determine the size branch necessary to supply the power to the load and the over-current protection.
For instance, a 1 hp pump would be 746 watts. At 240 volts, that would be a little more than 3 amps, when operating, and possible 10 amps during the first half-second when it starts up.

Can i run a 240 volt water heater on 120 volt?
No. A water heater requires a 240 volt connection and cannot be re-wired to run on 120 volts. There isn't enough amperage in 120 volts to power the heating rods that are inside.
A hot-water heater has an 8-ohm element that operates at 240 V The power that's consumed by this water heater is?
VOLTS x (VOLTS/OHMS) = WATTS 240 X (240/8) = 7200 Watts = 7.2KWatts
How many 240 volt electric baseboard heaters can you connect to a number 10 wire?
Depends on the Amperage of each baseboard heater (how many watts each one draws).
How many watts or amps draw on a GE water heater model se50m12aa01?
The GE water heater SE50M12AA01 is a 5500 watts or 5.5 Kilowatts water tank. The amperage on such a tank is I = W/E. Amps = Watts/Volts. Since most hot water tanks in North America use a voltage of 240, the amps will be 22.9 amps. It must be fed with a #10 conductor from a 30 amp breaker.
How do you use 110 heater to 220 volts supply?
You don't. The heater will operate over its given specified wattage. A 120 volt heater run off of 240 volt will have an output increase. Ohms law stated that current is directly proportional to the applied voltage and inversely proportional to the resistance of the circuit. A 240 volt heater can be run off of 120 volts but the wattage will be reduced. For example if an ordinary 1000 watt baseboard heater's supply is 120 volts, the current of the heater will be, I = W/E 1000/120 = 8.3 amps. The resistance of the heater is R = W/I (squared) =1000/8.3 x 8.3 (69) = 14.5 ohms. Applying 240 volts on the same heater whose resistance is 14.5 ohms results in a new heater wattage rating. W = E (squared)/R = 240 x 240 (57600)/14.5 = 3972 watts. This is 2972 watts, almost 300%, higher than the manufacturer's designed safety rating. The amperage drawn by connecting a 120 volt, 1000 watt heater to a 240 volt source will be, I = W/E = 3972/120 = 33 amps. W = watts, I = amperage, R = resistance in ohms and E = voltage.
What is the amperage of a 40 va 240 volt by 24 volt control transformer?
The formula for amps is I = W/E. Amps = 40/240 = .17 primary amperage. For the secondary amperage I = W/E. Amps = 40/24 = 1.7 amps.
Which outlets will need 240 voltage lines?
A stove, dryer, water heater, furnace, heat pump.
Can you wire up a 240 volt single phase water heater to 277 volt single phase?
no
What will happen if 120 volt appliance is plugged into 220 volt outlet explain with electrical equation?
If V is the rated voltage of the equipment, and Vs is voltage of the supply, we have this approximate equation: Vs = 2 V. That is enough to wreck the equipment and/or blow the fuse.120 volt appliance on 240 voltsThis senerio will use an electric baseboard heater but the results will be the same for any electrical appliance.The heater will operate over its given specified wattage.

What size of wire and breaker do you need for a 20kw electric furnace?
In order to properly size the wire per National Electric Code (NEC) standards you will need to know the amperage and the distance of the device (heater) from the source (circuit breaker panel). In order to know the amperage one would need to know the voltage since amperage changes inversely with voltage.
What is the amp draw of an open hot water heater element?
Check the appliance's specifications on the strip, tag or plate that is usually fixed either on the back or somewhere on the frame. On there you will find its required operating voltage and wattage that it draws.If your home has 240 volt line voltage just divide the watts by the volts for the answer.Example: a 2400 watt water heater for a 240 volt line using the formula watts / volts = amps would give you 10 amps. For a 120 volt appliance it would be 20 amps.
Can you run a 2 kw convector heater through a 25 amp trip switch at 240 volts?
Yes, the total amperage load of a 2000 watt heater at 240 volts is 8.3 amps. Keep in mind that the wire feeding the heater must be a #10 because the breaker is rated at 25 amps. A wire's ampacity rating can be larger that the breaker amperage rating but never smaller. Example, a #14 rated at 15 amps or a #12 rated at 20 amps can not be connected to a 25 amp breaker. The 25 amp breaker does not trip until it reaches 25 amps well over the allowable amperage of the #14 amd #12 wire. This is why a #10 wire must be used as its rating is 30 amps.
