Steps In Calculating Usage Costs
1. Total amperes of all equipment to be used on UPS.
Rule of Thumb:
(MMX PC's average 2.8 Amps beginning 1997)
(PCs average 3.5 Amps prior to 1997)
The average pool pump will have a rating of 7 to 10 amps and run 24 hours a day when the pool is being used. To figure the energy used to run this pump, we will first determine the amount of kilowatt-hours required for a month.
Kilowatt-hours can be found in the following steps;
Amps x volts = WATTS
10 Amps x 120 volts = 1200 Watts,
1200 Watts x 24 hours = 28,800 Watts, for one day.
28,800 Watts, divided by 1,000 = 28.8 kWh (kilowatt-hours) for one day.
28.8 kWh x 30 days = 864 kilowatt hours in one month.
864 kilowatt hours x your electric rate (Warren RECC's rate is .07) = the dollar amount.
864 x .07 = $60.48
