1/2 HP 120 volt pump

How do most people provide current to a water pump used to pump from a 1000 gallon poly cistern ? Is it OK to run a dedicated 20 amp, 120 volt circuit (with 12/2 cable) to a switch box in the joists above the pump, then from the switch, run the 12/2 to the terminal connections on the pump control box (a distance of about 3 feet down from floor joists) ? Does the cable need any physical protection between switch and pump ? Manufacturer just says to run 115 volts to connections. Pump is in an unfinished basement. Thanks.

I guess you would run the cable to a switch and then to the control box.
The wiring to the control box on the motor must be protected. You would need to use flexible metal conduit or sealtite from the switch to the motor.

You really should have a dedicated 20A circuit.
