In the best-case scenario, a well pump’s label will show you the amps it uses. If it doesn’t, you can use the horsepower.
A 3/4 HP well pump uses approximately 6.09 amps on a 120-volt system and 6.64 amps connected to a 110-volt circuit. If you go for the higher voltage, 240 volts, the number of amps won’t be as high. In this case, it will only be 3.05 amps.
