How do you attach an existing 240v 60hz 40 outlet box which has come out of the wall?

== == Turn off the power. Take the box apart. Attach the box to the wall either using the studs inside the wall (if there are no holes in the box to let you do this, you need to drill them into the metal box...if this is beyond your skill level call an electrician) Or else, attach the box surface-mount style if there is enough room behind the appliance. (If there are holes in the back of the outlet box, attach the box that way using screws to the nearest wall stud.)

IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOB

SAFELY AND COMPETENTLY

REFER THIS WORK TO QUALIFIED PROFESSIONALS.

If you do this work yourself, always turn off the power

at the breaker box/fuse panel BEFORE you attempt to do any work

AND

always use an electricians test meter having metal-tipped probes

(not a simple proximity voltage indicator)

to insure the circuit is, in fact, de-energized.

Most appliciances that are built for use with 220V would normally be fine with 240V. In most cases, they are also labeled 220-240V. Depending on how critical the application is, you should probably check with the manufacturer.

Yes, there is no problem using a transformer specified for 230V-50Hz with a voltage of 220V-60Hz. Transformers in this range of voltage are designed for 220 to 240V and 50 to 60Hz.

Could you please give us a name of a 240 V 60 Hz microwave? Thank you

In North America, the standard is 240V, 60Hz.

User Avatar

Treat the USA 2 Phases as 1, its called split phase, instead of Line and Neutral, you ahve two phases but they deliver 240v, this will not hurt a 230v machine as the chances are that you are NOT getting 240v supply at the delivery point anyway. As long as the machine si 60Hz and supply 60Hz, you will not have a problem

User Avatar

No India uses 240V at 50Hz the U.S. uses 110V at 60Hz.

User Avatar

It must state on the appliance, that it will work at 240v, 50hz. If it does not clearly state it on the name plate, damage to the appliance will occur.

User Avatar

It makes a great difference what the machine is as to whether is can work on a different frequency.

User Avatar

Yes, you can use a 60Hz variac in a 50 Hz outlet. However, since the frequency is less, the current and power dissipation will be greater, making the efficiency less. It will not carry its rated load.

No. The neon sign is fed by a step-up transformer. Primary side 120V, secondary side 7500V. If you applied 240 to the primary side you would get 15000 volts on the neon tube. A flash over and then nothing. If you can find a transformer from 120V to 240V or 240V to 120V then you are good to go. Connect 240V to 240V side and you will get 120V out the other, connect the 120V side to the neon sign and you should have light. Transformer should be at least 100va. This will give you an output of .83 amps at 120V

If it is a 120 240 v appliance you need to make sure it is connected for 240 v. Then if it has magnetic parts there might be a problem. In general equipment designed for 50 HZ is OK on 60 Hz but not the other way round.

User Avatar

no, i asked and search about this issue, doing this will damage the motor, wire, adaptor....etc with time

User Avatar

The frequency of the generated voltage depends on the speed of your engine. I assume it's a gasoline engine. It's probably spinning at about 3600 rpm. You need to get a mechanic to fiddle with the govenor and drop it down to 3000 rpm. 50HZ is 83 percent of 60Hz so you need 83 percent of whatever speed you are currently running. My question is, why bother?

User Avatar

The voltage isn't a problem, you can run 220 from your house and use that to run a European appliance, the problem is whether the appliance is dependant on line HZ. European is 50HZ and US is 60HZ. If the appliance specifies 220/50HZ, it will probably give you trouble here. If it says 220V/50 or 60HZ

User Avatar

You can but it would be wise not to. Most 60hz appliances will not work at 50 Hz. <<>> Yes, no problem at all. The frequency does not enter into the equation because the hot plate is a strictly resistive load.

User Avatar

If the kiln is strictly a resistance heating element, with no motor, then yes, it should work fine. Warning: the opposite, that is running a 240V 50hz (European) appliance from US 240V 60hz mains is very dangerous and should not be attempted.

There is a difference. For one thing, Australia works at 50hz and America at 60hz, and in domestic supply, Australia works at 240v and America at 110v.

User Avatar

It depends on the appliance; some motors rely on the mains frequency of 50Hz to operate at the correct speed so changing to 60Hz might cause problems. It's probably best to check the manufacturer's website for the appliance's specifications; that should say the range of mains voltages/frequencies supported.

Newer electronic adapters accept a wide input of voltages and support 50 or 60hz. Try to get that information from the adapter, if it has written "90-240V, 50-60hz". If you are not sure, ask an electrician since otherwise it could fail and destroy your electronics.

User Avatar

A transformer would get you from 208V to 240V, if you find one in that range. But a transformer alone would not get you from 60Hz to 50Hz - if you really need to do that. That'd take some fairly complicated power electronics to achieve that change.

I have a Maytag, two door with ice maker, and it works perfectly. Have talked with other expatriates and no one has a problem.
