How do you know if you have a 240 power supply or 120 power supply?

Some countries (Europe, Japan) use 120 volt systems. Australia uses 240 volt. One way of find out what voltage is used is to have a look at the pins on the appliances in the same area. 120 volt has round pins on the plug socket. 240 volt systems have 3 flat blades with rounded ends set at 30 degrees to each other around the centre of the socket
If you are in the US and have a residential 120/240 volt system and want to know if you should use 120 to ground or 240 volts phase to phase. You should check the voltage rating of the equipment you are wanting to use. Never exceed the voltage rating.

∙ 12y agocheck the power supply, it should say on the label of the PSU. Be careful though, power supplies can actually range from being ~50W to ~2000W.

How many amps does 320 watts equal?
On a 120 v supply 320 watts is 320/120 amps, or 2.667 amps. On a 240 v supply the current is 320/240 amps, or 1.333 amps.
What is my 240 v supply at home ac or dc?
The household supply in the UK is 240 V and is AC (alternate current).
Can you use 240 volts with a 120 volt supply?
Only if the cable going to your well pump is a three wire. The third wire could carry the neutral and you will have 120 volts from either 240 leg to the neutral.
How many amps does ti take to run 60 watt lightbulbs?
On a 120 v supply it takes half an amp, because 120 x ½ is 60. On a 240 v supply it would be a different bulb, designed to work on 240 v, and it would take ¼ amp.
Where you can buy an auto transformer 0 120 240 volt?
Try at a electrical wholesale outlet. Don't know why you would want a auto transformer. A standard 240 to 120 transformer usually does the job and it can be run backwards or forwards. 240 primary 120 output on secondary or 120 primary 240 output on secondary. Either way you will have to know the amperage of the load to get the correct size of transformer.
Can you use a 120 volt power bar with 240 volts power supply?
No, but check the specification on the power bar to see what its maximum voltage rating is. There will be a bit of cord end cutting to get the right configuration for 240 volt equipment.
How many amps does 320 watts equal?
On a 120 v supply 320 watts is 320/120 amps, or 2.667 amps. On a 240 v supply the current is 320/240 amps, or 1.333 amps.
What is my 240 v supply at home ac or dc?
The household supply in the UK is 240 V and is AC (alternate current).
Can you use a european light in US?
European lamps work on 230 v (240 v in the UK). In the USA the supply is 120/240 v with low-power appliances like lights running on 120 v. But 240 v is usually available in a US house so see an electrician.
Can you use 240 volts with a 120 volt supply?
Only if the cable going to your well pump is a three wire. The third wire could carry the neutral and you will have 120 volts from either 240 leg to the neutral.
How many twos are in 240?
There are 240/2 = 120 of them
What does 100 to 240 V mean for use in the UK?
If "100 to 240 V" is stated on the rating plate of a small electrical appliance, such as an electric razor or a plug-in power supply for something else, that means it is designed to operate on any voltage between 100 Volts and 240 volts. * So the appliance will work if it is plugged into a 120 Volt household AC power supply in the US, Canada or elsewhere in the world which uses a similar supply and * it will also work on a 230 Volt household AC power supply in the UK or any other country in Europe or elsewhere in the world which uses a similar supply.
Can a computer built in England on 240v work in a country that uses 110v?
Its all in the power supply. If there is a switch that lets you change the input voltage from 240 to 120 then you are fine. Most computers have this switch on the power supply, its located on the back of the computer up by the top. All you will have to do is change the plug on the cord to fit that country's 120 volt receptacle.
How many amps does ti take to run 60 watt lightbulbs?
On a 120 v supply it takes half an amp, because 120 x ½ is 60. On a 240 v supply it would be a different bulb, designed to work on 240 v, and it would take ¼ amp.
Why would a generator put out 240 volt single phase?
For a home generator, to supply voltage for devices that require 220 V or 240 V. An electric oven or clothes dryer are examples of such devices. The generator at the power plant actually generates electricity at a much higher voltage, for easier transmission (and those are 3-phase generators). Also most homes run on 240 single phase. Power is split at the breaker box. To supply 120 loads and 240 loads. 240 single phase is a common voltage.
Can you wire usa 4 wire 240 volt to UK 3 wire 240volt American boat in UK waters?
A four wire plug suggests to me that it is for split voltages. 120/240, hot - neutral - hot - ground will be the four blade connections for shore power in the US. With UK shore power three wire there will be no neutral as you know it. 120 volt equipment will not work. If there is a special berth for 120/240 shore power that is what you will need to tie up to.
Will a 240V 60hz cooktop Summit Appliance Three Burner CR3240 work in with 220V 50hz power?
The resistive elements will work. On 240 volt 60 Hz North American ranges there are clock and timer controls. These are operated on 120 volts. That is why these ranges are fed with a three wire cable. Two hots (240 volts) and a neutral (120 volts to either "hot" leg). A 220 volt 50 Hz power supply will not have a split winding to supply the range with its 120 volt source.
