Yes you can. Please be aware you have the situation of pulling more amps, in this case 5 amps, over the timmer before the fuse blows. which may damage the timer To avopid this appliances plugged into the timer should be rated at 15 amps or less. Thgere are different type circuit breaker immediate and time delay for where an appliance such as motors exceed the limit to start then drop down when running?

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.


Will a 220V 60Hz Air-conditioner run safely at 230V 50Hz?

Not really because motors are designed to run at either 50 or 60 Hz and the wrong frequency might cause them to malfunction or overheat.


How many receptacales on 20 amp circuit?

Answer for USA and Canada power supply service. Presuming a "15 amp circuit" is meant as a 120 volt system with a 15 amp single pole breaker with #14 awg wire, then: Per the National Electric Code, a breaker can only be loaded to 80% of rating. Thus, a 15 amp breaker can only feed a 12 amp max load. If the loads that will be plugged into the receptacles are unknown, then 180 watts shall be used for each duplex receptacle. Maximum load allowed on the breaker is 120 x 12 = 1440 watts. Maximum receptacles allowed on circuit is 1440 / 180 = 8. Still, read the NEC or other required codes depending on the installation location and connected equipment. In Canada, there shall be not more that 12 outlets on any 2 wire branch circuit. Such outlets shall be considered to be rated at not more that 1 amp per outlet. Where the connected load is known, the number of outlets may exceed 12 providing the load current does not exceed 80 % of the rating of the over current device protecting the circuit.


Can you plug a 115V fan into a 220V outlet?

No. the plug configuration is different, just for that reason so that the two voltages can not be crossed over.


How do you change 115v to 230v?

You need to use a 2:1 ratio transformer, with a capacity (in volt amperes) to match the load you have in mind.

Can you measure ohms from a live 115v AC outlet?

No, the circuit should not be energized when checking the resistance of a circuit.


Can you wire a 115v circ pump into a standard outlet?

Depends of the current draw of the pump and if there is any other load on the circuit.


Can you use a 115v in a 110v plug?

Yes, all wall receptacles are rated at 125 or 130 volts.


Can a 125 V replace a 115V GFI?

Yes.


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.


What voltage should you set your computer in the us?

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


How can you fix a receptacle that is not working if it has 115V on a volt meter but when you plug in a light it does not light and the volt meter drops to 0V and what is the problem?

To start I would check the connections on the receptacle. Next change the receptacle. It sounds to me there is a corrosion problem here...pkazsr

What is the maximum number of 60-W light bulbs you can connect in parallel in a 120-V home circuit without tripping the 30-A circuit 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.

Does 15amp outdoor circuit need gfi?

ALL outdoor circuits and all 115v circuits in a bathroom, kitchen or garage should be protected by a GFIC. If you have any doubt, contact your local building inspector.GFIC outlets are relatively inexpensive and can be wired into the first circuit of a string of outdoor outlets. The expense is reasonable and the protection is well worth the investment.


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)
