If you do the electrical conversion it comes out to approximately 746watts. Another person posted this unit is approximately 700watts. Either way, a 15amp residential circuit breaker will be more than adequate. If you are in a commercial setting, a commercial circuit breaker at 20amps is also more than adequate. Here is how to convert so you will know for anything electrical in the future. 746watts / 120volts = 6.22 amps 700 watts / 120volts = 5.83amps Max circuit breaker load as follows 15amps x 80% = 12amps max on a 15amp circuit. 20amps x 80% = 16amps max load on a 20amp circuit. You can never exceed 80% of the circuit breaker. So either way, 15amp residential circuit breaker is fine for this, especially if you are going to dedicate this circuit for the pump. If you are sharing the circuit with other loads, it is recommended you turn off whatever else you have plugged into the 15amp circuit. Remember, your maximum load can’t exceed the total of 12amps on that circuit. Same goes for the 20amp circuit breaker. Also, please take note that a 15amp residential circuit will typically have #14 AWG size wire (THHN insulation) used for that circuit wiring. A 20amp circuit will typically use #12 AWG size wire. Depending on the length of the circuit, the wire could be larger, but these are typically what us used. Anyway, it’s a lot of information, but this will help you sizing other circuits and appropriate size wire too. I try to pass along helpful information when I can **Q: With Adapter down to 3/4. No hose works fine, blows a ton of water..Put the 3/4 hose on and no pressure?** A: If you using the pump to remove water I would recommend getting a pool drank hose and use a hose clamp to secure it.
