Frequently asked questions
1. How does the electric company bill you?
Answer: They bill you monthly for each kilowatt hour (kWh) used.
2. What is a KW?
Answer: This is a metric term “kilowatt” or 1000 Watts of load or power of electricity.
3. How can we measure KW’s?
Answer: Voltage multiplied by the current or amps of electricity. This is the physical law of electricity called
“Ohm’s Law”.
4. How much does a kWh cost?
Answer: It varies from area and house to house. The average is 0.11 to 0.15 cents per kWh in the US, over .25
cents per kWh in the Caribbean depending on which island and to over a $1.00 per kWh other areas. Also,
electric costs increase on a yearly average of 8%. When viewing your electric bill, take the total cost of your
bill and divide by that month’s kWh consumption, this will provide your actual cost per kWh
How Much Electricity is Your 230volt Pool Pump Using?
A basic electrical calculation using “Ohm’s Law” requires obtaining the voltage and amperage of a device.
Ohm’s law states that if you know the volts and amps of a device, you can then calculate the Watts. Located
on the pool motor is the rating plate. Note that there will be two units of information required: 1) the voltage
and 2) the amperage.
Often times the motor will state two voltages and likewise two amperages. In regards to the calculation
sheet prepared for the Homeowner, this will have no effect on the outcome of the calculation. However, the
voltage will typically be stated as 115/230 and the amps will likewise state two amperages. The amperages
can be 18.6/9.3. When the motor is wired for 115 volts the higher or first number is used, and when wired
for 230 volts, the lower amperage will be used. Most pool systems are wired to run on 230 volts. Below is an
example of a 1.5 horsepower motor specification and the calculation to show how to determine the kilowatt-
hour consumption.
