Can I install a 10 amp Wayne 3/4 HP sump pump on an existing dedicated 15 amp circuit with 14 ga wiring? I just installed a Wayne 1/2 hp (replacing a failed 1/3 HP) and think I might need more as my discharge run is 125 feet even though the lift is only 2 ft... all underground This question has been moved to the discuss question page, leave it up for a week.
The size of the circuit breaker for a pool pump should be determined by the pump's current draw. The breaker should be sized to accommodate the pump's full load amperage with a 125% safety margin. Most pool pumps typically require a 15 or 20 amp circuit breaker.
A breaker is based on the amperage that is drawn by the pump motor load. Find the full load amperage of the motor. The wire fed from the breaker has to be rated at 125% of the motors full load amperage. The breaker for motors have to be over sized, usually 250% of the motors full load amps.
Yes, a 20 amp breaker requires AWG # 12 copper wire. A 15 amp breaker requires AWG # 14 copper wire.
When installing a circuit breaker, you size the breaker based on the wire size. The breaker should be matched to the ampacity of the wire to ensure proper protection against overloads and short circuits. The device being controlled by the breaker is not a determining factor in sizing the breaker.
you will need wiring that is at least 10 amp rated wire or higher. If you really needed to ask you might want to call an electrician Electrician here, be the pump 120 volts or 240 volts a #14 wire will handle the situation. Longer runs of 75 feet you should go to a #12 wire to compensate for voltage drop. The pump should be on its own separate circuit with a 15 amp breaker. A two pole 15 amp breaker if the pump is 240 volts.
Normally AWG #10 wire on a 30 amp breaker but it really depends on the size of the pump. The pump manufacture will specify the size wire and size breaker needed.
My heat pump was professionally wired when built in 2004. Wire is No. 4 AWG with 80 amp breaker

Ground wire connects to the ground bar, white wire connects to the neutral bar, and black wire connects to the breaker. Be sure and turn off main breaker before installing the wire or the breaker.
A circuit breaker does not have a wire fuse in it.
I think you mean 2 HP pump. I am assuming a 220 To 240 volt supply and that should equate to about a 12 amp current. All my pumps use only a 30 amp breaker and 10 AWG wire.
Yes, a 20 amp breaker requires AWG # 12 copper wire. A 15 amp breaker requires AWG # 14 copper wire.

You can't wire 2 beedrooms on one breaker.
