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.

How many 60 watt lamps can be driven by a 15 amp breaker?

If your not interested in safety or wiring codes use the formula. E x I = Va(Watts without knowing Power Factor.) E is your voltage at the source (Breaker) 110v, 115v, 117v. I is 15amp the breaker is rated for. X is your number of bulbs. example. 110 x 15 = 60X : 60x = 1650 : 1650/60 = X Please do not attempt doing this hookup. % If your not interested in safety or wiring codes use the formula.

Is there a 440 voltage rating?

There was a 440 Volt Rating. Voltage ratings of the past gave way to higher levels to allow larger power dissipation from the same wire size. In home use 110 Volts gave way to 115 Volts and that gave way to the 120 Volts of current use. Higher voltages also increased in turn as 110V associated with 220 and 440 Volts, became 115V associated with 230 and 460 Volts, and today we have 120V associated with 240 and 480 Volts.


Can a television bought in Hong Kong with a DMB-TH integrated digital tuner be used in the USA which uses a ATSC digital broadcast system?

The tuners are not compatible but other inputs to the television are likely to be compatible. You will need to check that the television can operate on 115V. Hong Kong uses 230V. The information panel on the rear of the television will say what voltages it requires.Also, check that the television is capable of handling NTSC / 60Hz signals. Hong Kong is a PAL / 50Hz region so you will need to confirm that the television will accept North American content.If the voltage ad video capabilities are compatible, the television will work with satellite or cable receivers and terrestrial digital tuners as well as DVD and BluRay players.

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.


Can you run a 115v electric motor on a 110v home outlet?

Yes, no problem with a small change of voltage.


How do you wire a 3 wire 115v 15 a pump motor?

Black to black, white to white and ground to green terminal on the pump.


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.


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 many amps does a 1 hp motor pull running on 115 v power?

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.


Will a 115V 60Hz work in a 120V 60Hz power supply?

Yes, 115V 60Hz will work in a 120V 60Hz power supply.


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)


Will a 220v 50hz work in a 115v 60hz?

No.
