25 amps and it should be run through a contactor and motor over load set,you should set the over load to 5% above the motors full load current.And not your breaker should be a d curve type with 6ka rating.

What size breaker is needed for a 115V 60HZ motor?

Its been a while since ive brushed up on my electricity knowledge, but im fairly certain that breaker capacities are based on amps. I think you would have to know the amperage of the motor before you were able to conclude what size you need.


Do i need to switch circuit breaker since i went from 115V well pump to 230V well pump it is also a higher HP pump but pressure is lower than before?

The 230v breaker is 2-pole, The 115v is only single-pole so YES you need a new breaker. DON'T use 2 single-pole breakers instead. The well pump will run to the pressure setting of the pressure switch controlling it, regardless of HP. The difference might be in the size of the pump in flow rating, I.E. a 1/2 HP pump rated at 10gpm @ 70 psi won't perform the same as a 3/4 HP pump rated at 20 gpm @ 50 psi. Check the pump curve and pressure switch setting. The pressure switch for the new pump will need both power leads connected to the switch (1 lead per contact set), not 1 wire as the 115v motor was.


Is your new swimming pool miswired if the pump motor is installed but don't know if the wiring to pump is 110v or 240v and you set pump up for 110v and wired it but only hums and trips breaker?

Yes. Get a volt meter and check the power at the timer. It sounds like you have a switchless motor with a bad run capacitor and a week breaker. That's about a $20 fix.Check power on line 1 line 2 with the meter set at around 500 volts a/c- you should get 230 or so, most pumps are 230 volt. Another thing- if it has a skinny breaker, 115v if it's a wide breaker, 230v.Step 2 Take the motor to a qualified repairman, as they will usually test it for free.If you are uncomfortable with your lack of electrical experience, make step 2 your step 1.


How do you calculate amp draw for 115v 1 phase and the breaker size?

To calculate the amp draw of a device you need to use one of the following three formula. I = W/E, I = E/R, I =√W/R. Once the amperage of the circuit is found then the size of the breaker can be established.


You have an old Gould 2hp elect motor that you want to switch from 230v to 110v The existing connections do not match directions in earlier question and suggested 110v connections differ from mtr diag?

2 HP, A-C Single phase, 115/230 volt motor. And you wish to operate it on 115V. First the circuit size would need to be a min. of 30amp/ #10wire.... Being a Gould is this a pump/motor? I ask because single phase pump motor are not reversible, so they have less leads to connect..Is the motor thermaly protected (check name plate) Again less leads to connect if not therm-protected. How many lead motor is it, and what are the leads #. If it is 4 leads and # t1,t2,t3,t4 connect line1 to t1 and t3 connect line2 to t2 and t4. Let me know what the # are and how many leads their are.. I would not operate a motor that large on 115V, (1HP is about max on 115V)


How many amps does a 1 hp electric motor pull under a load?

T430.247 of the NEC shows that a 1 hp motor operating at full load on 115v will draw 16 amps, called Full Load Current (FLC). Conductors supplying this motor are required to be 125% of FLC which is 20 amps. Motor circuits are complicated things and do not follow the rules of other circuits. This motor, while drawing a maximum of 16 amps at full load and supplied with #12 AWG copper conductors can be protected by a breaker of 40 amps.


Why will your outside compressor for your central air unit come on but the fan motor will not come on and there is a gurgling sound coming from the furnace?

If I understand your question correctly, your indoor fan motor is the one not running. If that is the case, the gurgling sound you are hearing is the refrigerant being pumped into the indoor coil. You need a new motor. If this is a gas furnace, you need a 115V motor; if it is a heatpump, you need a 230V motor.


You have an Emerson motor for an Arctic Circle swamp cooler model k55hxjbr8989 1 8 hp 115v 60hz 1 phase rpm 1075800 where can you find a replacement motor in the riverside San Bernardino ca area?

I'm looking for a replacement motor for Emerson k55hxjbr-8989 1/8


What is the maximum number of watts and amps of a 115v AC?

there is no limit look at your circuit breaker it will say example my single pole breakers are 20 amps which according to OHM's law says that is equal to a maximum of 2300 watts (Voltage X Current = Power)


Can a 125 V replace a 115V GFI?

Yes.


What voltage should you set your computer in the us?

In the U.S. you should be using 110-115V.


Can you use a fusible link wire with 115V AC current?

no
