for USA, Canada and countries running a 60 Hz power supply service.It is important that you should read see the answer to the Related Question shown below: "Can a European 230 Volt 50 Hz appliance be plugged into a 240 Volt 60 Hz wall outlet in USA or Canada?"

<><><>

Asking this type of question usually means you aren't ready to do this yourself.

If you get any detailed "how to do it" answer here, you might attempt to do something you shouldn't be doing, and that may cost someone a shock, a home fire, or their life.

<><><>

As I don't know what you are trying to power, be sure to check the frequency requirements (50/60hz) before you start. Most appliances won't mind, but better safe than sorry.

As another poster pointed out

  • Green/Yellow is ground. Bare wire in the US
  • Brown is hot. Black is hot in the US
  • Blue is Neutral. Connect this to the Red hot wire as we can't use the US neutral. (It is a Neutral for a 120V hot.)
  • If you encounter a White wire in your supply cable, cap it with a wire nut. That is the neutral for 120V we are not using in this appliance.

Also, as you are only 3A away from the limit on the circuit you may want to consider running a 40A line to this appliance. Make sure all the wiring can handle it, though, including the wiring in the device.

As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed

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 electrician's test meter having metal-tipped probes

(not a simple proximity voltage indicator)

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

IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOB

SAFELY AND COMPETENTLY

REFER THIS WORK TO QUALIFIED PROFESSIONALS.

Need to know what the wattage or the amperage is of the appliance. The load amperage is what governs the wire size and the breaker to protect the circuit.

User Avatar

A small appliance circuit will be protected by a circuit breaker rated at 15 amps if the circuit wires are #14. If the circuit wires are #12 then a 20 amp circuit breaker could be used.

User Avatar

The number that is on a breaker is the amount of amperage that the breaker can deliver before it trips. This is the same regardless of how many poles the breaker is.

User Avatar

I assume you want to know what size breaker to use? You need to find out the KW rating of the appliance. This will be stamped on the appliance data badge ( usually on the underside ) divide this by 230v For instance oven is 6.3kw so 6300/230 = 27.39 This figure is the amount of amps the appliance will consume so take the next highest breaker above this figure. So 30AMP breaker/fuse. Hope this helps!

The appliance works perfectly. If you did it the other way around (50amps on a 30amp breaker, you would be tripping the breaker. Think of it as a mercury thermometer. The circuit breaker is the maximum temperature and the load on that breaker is the mercury. If the load is lower than the max, everything works beautifully. If the load becomes greater than the maximum rating, then things starting popping.

If the appliance is just to be plugged into a circuit with multiple outlets then you just need to make sure that the sum of currents for all devices on the circuit are less than the rated current. A rule of thumb is total current should be no greater than 80% of the rated current. So you might have a 20 A breaker and several 2.5 A appliances on this circuit. If you have a dedicated circuit for the appliance you would only need to size the breaker for the maximum current being drawn by the appliance. If the appliance contained a motor then there might be a start-up current that might be as high as 15 amps so you would likely go to a 20 amp breaker for a safety margin. As a practical matter a dedicated circuit for an appliance in the 2.5 amp range should have a 15 amp breaker. I always install a 20 amp breaker just for added margin and possible future applications.

No the breaker will trip beause the circuits maximum current allowed by the breaker is 15 amps.

A vacuum breaker is usually installed at the top of a vertically-mounted drain pipe leading to a drain. The water drainage hose from an appliance such as a dishwasher or washing machine should never be plumbed directly into a drain stand pipe without a vacuum breaker. The vacuum breaker prevents contaminated water from the drain being sucked back into the appliance if it has a fault.

User Avatar

breakers are rated by wire size, not voltage. the appliance manufacturer will probably specify amperage.

User Avatar

that would really depend upon the stove (I assume that you mean an appliance with an electric cooktop and an electric oven) and the size of the wire present. Most of the time a stove will require a 50amp breaker. This will mean that you would need to have 6 gauge wiring. You can probably get by with a 40 amp breaker and 8 gauge wire if you absolutely had to. Always check the appliance specifications. they will recommend a breaker size.

User Avatar

In North America this size breaker could be used on a welding machine. A range in the home would use a 40 amp two pole breaker.

User Avatar

Is a load(appliance) that runs at max current for 3 hours or more at a time.

User Avatar

You may need to call in an electrician, or appliance repairman.See view discussion below.

User Avatar

If you plug it in you will trip the 15 Amp breaker protecting the outlet.

User Avatar

Usually it blows the circuit-breaker and it might also ruin the appliance.

User Avatar

You probably popped the breaker. The appliance is drawing too much current for that circuit (or is combined with too many other appliances on that circuit). Unplug it, turn the breaker back on. Try to find a different circuit to operate it on, or move other appliances to other circuits to reduce the load. If you own your residence you might be able to hire an electrician to completely rewire that circuit with larger capacity wire and breaker and changing the outlets also. This will get expensive though. I cannot use my microwave cooker and my stand mixer at the same time, together they will trip the breaker for the kitchen outlets, but one at a time is OK. It might also be an earth fault in the appliance - As stated turn off other appliances on the same circuit (that should cancel out any over load) and test again . If the breaker drops then the appliance is the issue

In North America the smallest breaker to be used in the home electrical system is a 15 amp breaker. These breakers are used to protect the lighting and receptacle circuits. The capacity of a 15 amp breaker is enough to power most small appliances for the home. Larger appliances will need larger size breakers and usually are dedicated to the one appliance.

User Avatar

First you need to read the manufactures mane plate to find out the amperage of the appliance. Then you need to runs run a wire size to that amperage to a breaker that matches the manufactures specifications. Finally you will need a plug and outlet that that has a NEMA number that corresponds with the amperage and voltage of your appliance.

Turn every appliance and device on in the house. If the main breaker trips, turn a few devices off until the breaker does not trip. Prepare for a bill in the hundreds of dollars.

User Avatar

No, but that is beside the point since it is also very dangerous. I have no idea how it could be hooked into the power system without a breaker. It would have to be a real Jerry-rig.Another perspectiveAs the above response indicates, it's very dangerous to connect any appliance without the protection of a breaker. You ALSO need the ability to shut off power to an appliance. You should immediately contact a qualified electrician and have the condition corrected.

Check the MFG for the amps it uses, if it is suppose to be on a regular 20amp line, then replace the breaker with a 20amp breaker. With the 30amp breaker,it will work, but if there is a surge, you could send too much power to the appliance and fry it. Most refrigerators, are just on a regular 120v household outlet. Besides a 30amp breaker must have 10ga wire, if the wire is 12ga,it can not be attached to a 30amp breaker.

User Avatar

First, determine the current necessary to operate the appliance. Read the installation manual to find out the manufacturers recommendations. If the existing outlet does not supply sufficient current to operate the appliance, you'll need to run a new wire and install a larger breaker in your main breaker panel.

A three-prong plug on an ordinary appliance contains a third conductor connecting the metal parts of the appliance to a safety grounding wire in the receptacle. In the event the line voltage wires become disconnected inside and touch the metal parts, the safety grounding wire will provide a short-circuit for the hot (blowing the breaker) and provide an alternative path to ground (for the open neutral), avoiding instant electrocution of a person touching the defective unit.

A circuit breaker is an automatically operated electrical switch.Its protect an electrical circuit from damage over load and short circuit. A circuit breaker can be reset to resume normal operation.AnswerIt depends on the circuit breaker. A miniature circuit breaker, for example, contains a bimetallic temperature sensor (overload current protection) and a magnetic trip (short-circuit current protection). On the other hand a high-voltage circuit breaker contains no sensors but relies, instead, on external protective relays which, when activated, energise a trip coil within the circuit breaker, which trips the breaker.
