About 6 amps is average for a 1/3 hp motor operating at 120 volt. Its a good idea to have it on a dedicated circuit or a circuit thats ” known” not to have alot of load on it. 4 of 4 found this helpful.
How much electricity does a 1/3 HP sump pump use?
Small pumps like 1/4 HP and 1/3 HP tend to cost about $10 to $20 per month to operate. Larger pump with 1 HP motors or larger can cost $30 to $40 per month to operate. Keep in mind the cost will spike during the wet spring months and during months where snow is melting due to an increase in ground water.
How many amps does a 1/2 horse sump pump use?
When running, a half horsepower motor pulls about 5 A. It can pull 15 A to start for a few seconds. A 15 Amp breaker usually works but I go 20 Amps and 12 AWG wire for new install. But many sumps run just fine on old 14 AWG wire and a 15 amp slow blow breaker.
How much current does sump pump draw?
If the motor is like 80% efficent, then your continuous could be 373/0.8 = 466 watts. But they say the startup draw can be 1.5x-2x the continuous draw.. so you might consume up to 900+ watts. That’s roughly 7.8 Amps.
Can a sump pump be on a 15 amp circuit?
Re: Sump Pump Wiring ??? It need not have 20 amp receptacles, however. If it’s a 15 amp circuit, either #12 or #14 could be used, as a lower amp circuit can always safely use wire rated for a higher amp circuit.
How many amps does a 1/3 HP sump pump draw?
About 6 amps is average for a 1/3 hp motor operating at 120 volt. Its a good idea to have it on a dedicated circuit or a circuit thats ” known” not to have alot of load on it.
How many watts does a 1/3 HP sump pump draw?
1/3 hp sump pump The starting wattage for that size is 1,300 watts which fits nicely between the ¼ and ½ sizes. The average running watts is 800, again inbetween the two sizes, so you’ll need a generator that provides that degree of power.
Should a sump pump be on a 20 amp breaker?
Electrical Wiring for a Sump Pump Circuit The wire size that should be used for the 20 amp septic sump pump circuit should be #12 gauge. The sump pump should be protected by either a GFCI outlet or a GFCI circuit breaker.
How many amps does a 3/4 hp motor draw?
AMP DRAW BASED ON HORSEPOWER HP 1 Phase Amps 115 volt 230 volt 1/2 9.8 4.9 3/4 13.8 6.9 1 16 8.
What size breaker should I use for a sump pump?
Use the Proper Size Breaker If your pump has a motor surge output of 10 amps, use a 15-amp circuit breaker in the breaker panel to allow it enough power to start up but not enough power to burn up if something goes wrong.
Should a sump pump be on its own breaker?
The power supply to a sump pump should not only have a dedicated outlet, but should also be a Ground Fault Circuit Interrupter. The sump pump needs its own circuit breaker to prevent tripping of the breaker and the Ground Fault Circuit Interrupter is essential in preventing electrical shock.
How many amps does a well pump use?
A 240 volt, 1 horsepower well pump draws 10 amps of current. When the pump starts, it can draw up to 35 amps, but only for 5–10 seconds.
How long will a 12v battery run a sump pump?
As a general rule of thumb, during a power outage most new fully-charged batteries will last roughly 5-7 hours of continuous pumping and roughly 1-3 days of non-continuous pumping depending on the frequency. The longer the pump runs, the less power it has.
Is a GFCI outlet required for a sump pump?
There is no NEC requirement for GFCI protection for a sump pump. The 2008 NEC removed the exception for 120 volt non-GFCI receptacles in dedicated spaces in garages and unfinished basements.
Can a UPS power a sump pump?
Although inverter/chargers and UPS systems work in very similar ways and perform similar functions, the battery in a UPS is not large enough to run a sump pump for any significant length of time.

What watt generator do I need to run a sump pump?
Mid-sized generators (3,000-5,000 watts) can be used to simultaneously power a sump pump, refrigerator and other key appliances. A 5-kilowatt portable generator can power a heating system and a few other essentials. Large generators (6,000-9,000 watts) will power key appliances and energize several rooms in a house.
Will a power inverter run a sump pump?
You can get a power inverter to run a sump pump and get all the cables from the same source as the power inverter. Make sure you have a full tank of gas and will be awake to monitor the sump pump.
