Appliance Voltage and Travel Issues

Yes. With SOME, you may need a motor-generator set, or an inverter, to convert the single-phase power to three-phase power....

Some more modern 3-phase welders will operate directly on single-phase, because they're inverter-type units already.

Many 'classic' transformer-based industrial welders can be made to operate easily off single phase power, at full output using the "Haas-Kamp Conversion". Do a web-search for Haas-Kamp and your welder's brand and model- if it's a popular welder, someone has probably already done it.

To calculate amperage, use the formula: Amperage = Wattage / Voltage. For a household appliance with a wattage of 720 and a standard voltage of 120 volts, the amperage would be 6 amps. (720 watts / 120 volts = 6 amps).

NO! The National Electric Code requires a partitioned box when high and low voltages share the same box. Always avoid installing different voltages in the same box, it's a bad idea.

A 277 volt switch has a different screw to box configuration that a 120 volt switch. This is also true for 347 volt switches. The switch is configured this way so that 120 volt switches can not be used on the wrong voltage inadvertently

According to the 2008 NEC 300.3 C 1 says yes as long as all the conductors in the wiring enclosure have at least an equal insulation rating as that of the maximum circuit voltage applied.

This is a highly unlikely scenario due to the fact that 120 volt and 240 volt receptacles have different pin configurations. The TV 120 volt plug end (cap) would have to be cut off and then a 240 volt cap put in its place. The money spent just to ruin a TV seem a little out of place.

When a light bulb receives more than 120 volts, it will likely generate more heat than it is designed to handle, causing it to burn out or potentially shatter. This can be a safety hazard as the excess voltage can lead to overheating and fire risk. It is important to always use the correct voltage for light bulbs to ensure proper functioning and safety.

To convert 12 volt trailer lights to 24 volts, you would need to install a voltage step-up converter or a voltage doubler circuit in your trailer's electrical system. This will effectively double the voltage to the lights, but make sure you choose a converter that can handle the power requirements of the lights and wire it correctly to ensure proper functionality and safety. It is recommended to consult a professional electrician or mechanic for assistance with this modification.

it depends on where the neutral is lost

if its loose on the street side of the meter or grounding electrode conductor one leg will have a higher voltage than the other but the grounding electrode conductor may be large enough to act as the neutral and remove all the phase imbalance

this will show current in the ground

on the load side everything will look normal

if you have 4 identical lights

2 on each leg you will not detect any difference

if you turn off one lamp

the lamp on that leg will supply the current to the two on the other

letting the single lamp see 160 v 50% brighter

and the 2 in parallel on the other leg 80v 50% dimmer

triplex wire the bare wire is the neutral and the messenger

so if a furniture van pulls to the door an snags the cable.

the neutral will break leaving about 6' of slack in the hots.( drip loops at the weather head) and they stay connected

the grounding electrode conductor is likely connected to the water line and every house on the street is too so the voltage across the break will be less than 1v unless your phase loads are all on on leg which will mean on the order of 1V

delta V= i^2*r (#2Al neutral)- i^2*r (#4cu grounding electrode conductor)

Because it causes a lot of money to be spent. Water is a good conductor and causes the high voltage to be applied to your body. This causes the body to convulse, twitch, and eventually die. A ambulance ride to the hospital costs money. The coroner charges a fee to pronounce you dead. Then there is the expense of the funeral home. All in all, an expensive situation you don't need.

No, you should not plug a device that requires 125 volts into a 220-volt outlet as it may cause damage to the device or create a safety hazard. It is important to always use the correct voltage outlet for your devices to prevent damage and ensure safety.

No, 240 volt appliances from New Zealand cannot run on 240 volts in the US. The electrical systems in these countries are different. Appliances intended for use in New Zealand are designed to operate on 230-240 volts at 50 hertz, while in the US, the standard voltage is 120 volts at 60 hertz. Using a 240-volt appliance from New Zealand in the US without a voltage converter or transformer could damage the appliance or pose a safety hazard.

If you want mood lighting just connect it as is, the brightness of the bulbs will be half. If you want full brightness change the bulbs to 120 volt with bulbs of the same wattage as the 220 volt bulbs.

The four largest countries in the world by land area are Russia, Canada, United States, and China.

If the appliance is turned on, then it will most likely be destroyed. 120 V appliances simply are not rated for 240 V.

Check the applicance's voltage rating. For example, a certain U.S.-made name-brand portable dryer for apartments uses 110 volts, but its voltage rating is 240 volts. Often, if you don't have the specs or the container any more, a quick test is price: If the price was high/normal, it may have the higher voltage rating and is worth researching. If the price was low, it may be damaged. So, you get what you pay for. Here is a follow-up question: Does anyone have views about adapters sold on Amazon's site? Do they work and do they work both directions (step up and step down)?

It could be a faulty transformer, a fault in insulation in the wiring, or improper grounding. If you read 80 volts between hot and 'ground', but 120 volts between hot and neutral, then it's most likely a grounding issue.

Generally, if the electrician did it right, the BLACK wire is HOT, and the WHITE wire is NEUTRAL. Meaning that the white wire is the center tap of the main transformer, and the black wire(s) are either leg of the 240 volt output. Since the hot to center tap only takes half of the 240, it ends up being 120 volts at your outlet.

The power rating on the converter won't be high enough. You cannot exceede the power capacity of the source, no matter how hard you try. In the US outlets are 15A at 120V. 15A * 120V = 1800W. No matter what you do, you cannot draw more power than that from the outlet. Also, you are limited by the weakest link in your chain. The next link is the converter itself. If you can get a converter with a power rating higher than your appliance, and the appliance draws under 1800W, then yes, you can power it with a converter. (Though, if it draws 1800W, or over 1500W to be practical, it will need a dedicated line.) So, for a small appliance bought overseas, yes this will work. For Ranges and Dryers, no it will not. There is a reason they are not designed to plug in to regular outlets. Range: 50A at 240V: 12,000 Watts max. 6.7x the amount of power a 120V outlet can supply. Dryer: 30A at 240V: 7,200 Watts max. 4 times the amount of power a 120V outlet can supply. The previous answer is not correct. Of course you can. There's absolutely no reason why it would not work. The outlet and the power source it is connected to has no limit as to the amount of power that can be drawn, for all intents and purposes. The current is artificially limited by the circuit's fuse/circuit breaker for safety reasons. Given sufficiently thick wire, the circuit can draw 50, 100, 200A with no problem. The reason the circuits are current-limited is due to the relatively thin wires between the power source and the outlet. Thinner wires heat up faster as the current passing through them increases. At a certain current level, the wire can heat up enough to be a fire hazard. A step-up transformer is simply wire wrapped around two iron cores. One side is connected to the 120V source (the outlet). The other side is connected to the appliance. The changing voltage on one side (AC) induces voltage changes on the other side proportional to the ratio of the number of turns of wire. This is basically the opposite of the step-down transformer connecting your house to the power grid. What would you use instead of a step-up transformer anyway?

Yes you can. The maximum charge current for LiPo batteries is '1C' where 'C' is the capacity of the battery in question, in your case C is 2000mAH. So you will be charging at 0.5C which is fine.

Yes, the 9 volt 800 milliamp adapter will work with the 9 volt 400 milliamp device. The device will only draw the amount of current it requires, so having a higher amperage rating on the adapter is fine. The voltage should match to ensure compatibility.

Domestic electric wiring is typically rated for a voltage of 120 to 240 volts and a current capacity ranging from 15 to 20 amps for standard residential applications. It is important to consult with a qualified electrician to ensure that the wiring meets the specific needs of your home and adheres to safety standards.

Look on the dryers nameplate for the actual wattage. Lets assume that it is 7200 watts. You pay for electricity by the killowatt/hour. So you are using 7200 of 7.2 Kw/Hr. Look on your power bill and it should tell you how much they are charging you per Kw/Hr. It could be .04 to .15 (who knows). Mine is .06 cents per Kw/Hr. Calculate .06 x 7.2 = .432 cents/hour

Except that the heater is only running for part of the time, so in reality this depends on what you set the temperature to. 50% duty cycle is probably a good estimate, in which case it will be about half of the above.

Not necessarily. Amperage (amps) and voltage (volts) measure different aspects of a power tool's performance. Amperage relates to the tool's power consumption, while voltage relates to its power output. It's important to consider both factors and how they affect the tool's overall performance for your specific needs.

To convert 7620 volts to 240 volts, you would need to use a transformer. The transformer would step-down the voltage from 7620 volts to 240 volts. The ratio of the turns on the transformer primary and secondary windings determines the voltage transformation.

To use UK appliances in Singapore, you will likely need a plug adapter to fit the UK plug into a Singapore power outlet. However, be sure to check the voltage requirements of your UK appliances as Singapore uses 230V while the UK uses 240V. Some appliances may be dual voltage or have adapters to adjust for voltage differences. If not, you may need a voltage converter to ensure compatibility.

To determine the correct size circuit breaker for a well pump, you should check the manufacturer's recommendations on the pump's label or in the manual. Typically, most well pumps require a 15-amp or 20-amp circuit breaker for residential use. Make sure the breaker is appropriately sized for the pump's power requirements to avoid damage or safety hazards.
