So you could use a transformer (LINK)

or you could get a local power supply pack.

Read the label on back of power pack that attach's to wall socket and charger base, see what input it can handle, some gear can handle like 110v-230v, others cant ie will read 120v

Any adaptor that puts out the same output as the original would work ie 18v DC 2.5 amps is your specs i beleive so use a transformer or another suitable adaptor

Please check my quoted specs are the same as listed on power pack of your charge ie I am assuming you are using your 110v A.C. to 18v 2.5amp D.C power pack

I purchased remington shaver in US now it not working properly and not getting charged. where do i have repairing centre in hyderabad


Many Remington shavers sold in the US are only for use with 120V. Voltage in your country may be 220V-240V. If you attempted to use a 120V charger in your 220V electrical outlet without a voltage converter, you have probably damaged the charger.
Chargers can be purchased at shaveroutlet.com. You will need your shavers model number to select the correct cord. And, you may need to use a voltage converter if the replacement you get is for use with 120V

What to do if a 120v machine gets plugged in to a 240v outlet?


Just buy a new one. Every electrical component has been stressed to the point of destruction. Any fuse if there is one is there to blow in the event of a dead short, but you applied double voltage to every component.

I want to change 120v charger to run on 240v.What components have to be changed?


Can't be done.
Even if there was a safe way to put power to the neutral wire, the fact is you would still be running more than twice the power through it, and it would blow up. It would get much hotter.
Nor would the charger put out 7.2 to 18 volts any more.
It would put out over twice that.
The only way it could be done is if the unit was intended to also be run on 240 volts, and had a European selection setting switch.

Can you put a aussie 240 volt plug on an US battery charger


Look at the specs on the label, if it says that the charger is capable of taking a 240v input then you can change the plug and use it at 240v with no problem. If it says 120v then you won't be able to, you'll want to use a transformer or some other 240 to 120v supply.

How to wire a intermatic timer T104 240 v to a 120v?


T104 is 240volt timer.
Timer has terminals A 1 2 3 4
T-104 clock motor must receive 240Volts to operate.
Clock motor wires are white-colored and can be seen connected to terminals 1 and 3.
http://waterheatertimer.org/How-to-wire-T104-Intermatic-timer.html
http://waterheatertimer.org/images/Back-of-WH40-2b.jpg

There are two work-arounds for using T104 for 120V.

1) Diagram 1 showing how to change wiring:
http://waterheatertimer.org/images/T-104-control-120V-Load-500.jpg
Move 240V clock motor wires to terminal 1 and A.
Connect 240V Hot leads to terminals 1 and A. This will power the 240V clock motor
Hot wire going to 120V load connects to terminal 2. This wire will be turned on each time timer turns on, and 120Volts will power the 120V load.
To complete 120V circuit, neutral wire that comes from neutral busbar in breaker box connects to 120V load.

To control additional 120Volt circuit, run jumper wire from terminal 1 to terminal 3.
Connect Hot to second load to terminal 4.

2) Second method is to change T104 timer into T103 timer:
http://waterheatertimer.org/images/T-104-control-120V-Load-2-5.jpg
Replace T104 240V clock with identical 120V clock motor from Grainger
http://www.grainger.com/Grainger/INTERMATIC-Time-Clock-Motor-1PNK1?Pid=search
Neutral wires connect to terminal A.
Hot wire from Breaker connects to terminal 1
Hot going to Load connects to terminal 2

To control additional 120Volt circuit, run jumper wire from terminal 1 to terminal 3.
Connect Hot to second load to terminal 4.

Fixya answers questions about other people's products.

I specialize in timers.
Intermatic is changing their product line
I suggest you download the manual:
http://www.intermatic.com/~/media/files/intermatic/products/instructions/timers/et104c%20-%20english.ashx

The manual is generic across all the ET100 series products.
The manual does not describe individual models.
The instructions are on the timer door.
Look for the clock voltage.
The clock voltage tells the story of your timer model.

NOW lets say your clock voltage is 120V.
I believe you suspect the clock voltage is 120V.

To make this timer work with your 240V cable, there are 2 methods

Method 1) To meet code, run a white wire from nearby 120V receptacle.
This is a Neutral wire.
Connect the Neutral to terminal 1
Connect one leg from the 240V cable (1 of the 240V wires) to terminal 2 and that will complete the 120V circuit and the clock will run.
This is true because each leg of a 240V circuit is actually 120V, and only when the two legs are combined do they produce the 240V circuit

Method 2) Connect bare ground wire to terminal 1 and to grounding screw
The bare wire connects to the Neutral busbar in the main breaker box, so it will complete the 120V circuit just as described above.
This is not code, but your clock will operate.
Then connect one leg from the 240V cable to the terminal 2

IF your clock is 240 V, then connect both legs of the 240V cable to terminals 1 and 2
