Why 220v is better than 110v

I run on everything I can. I do see a real improvement over Tablesaw is vitrually instant to max rpm. Staff member. Corporate Member. I agree with Skymaster. All of my tools on perform better. Bas Recovering tool addict Bas. Rjgooden said:. Click to expand Higher voltage will mean lower amperage for the same HP 34 amps needed to run a 3 hp motor so 10 or 8 wire needed to feed the motor on v vs 17amp on 12 wire only needed.

Also as others pointed out it start is way better. Final thing will be cheaper if the motor is starting and stopping all the time highly unlikely but that would be the only time it would show any savings in power use albeit small. Brian Patterson New User Bstrom. So the Europeans had the right idea all along with being a de facto voltage? How did the US get saddled with a V standard anyway? Was it a safety issue? Europeans lagged the US in electrification.

Edison's original light bulb worked on V DC. Europe electrified when bulbs that worked on higher voltage were available. A lot of this is pretty arbitrary.

Europe also is 50hz where our power is 60hz. That means a typical European turbine spins at rpm while ours spin at nuclears are half with four poles. What will kill you is enough current across your chest. At twice the voltage enough current is easier to get. I don't think that what Europe does is generally better and it isn't in electricity. However, you should still use caution especially when you wire v.

While most consumer goods, including portable electronics and most appliances, run on v power, some require v. Appliances, such as dryers, certain oven ranges, heavy-duty power tools, and compressors explicitly require v power. A typical v wiring schematic requires three different wires: hot, neutral, and ground.

With v wiring, both three and four-wire setups are possible. The red and black wires in v setups each carry v, and the green wire is the ground. With four-wire setups, there is a white wire which is called the neutral or common wire. When the wiring is complete, the respective outlets for v and v power are different as well. Standard v outlets are made for three-pronged plugs, the middle of which is the ground.

The other two are made in different sizes so there can only be one way to insert the plug. With v outlets, there are either three or four holes per outlet. When wiring for v power in your home, you have to link the current in amps with the voltage of the particular wire to create the wattage necessary to power dryers, power tools, and so forth. Do not be confused by this; think of them as one and the same.

The 2 most common variations are 15 Amp and 20 Amp. Some areas will also charge for a permit to do this work. Visit your local hardware, home improvement or small electrics retailer and ask for a stepdown converter that will convert your V dryer to a V dryer. In general, bury metal conduits at least 6 inches below the soil surface. Yovani Pylev Teacher. Why is v more efficient than v? ELI5:Why are power supply's more efficient at v than v?

A V power supply takes in half as much current as a V power supply, this means power lost to a fixed voltage drop like in diodes is cut in half and power lost to resistive heating in resistors is cut to a quarter.

Hafssa Batalau Supporter. Why are building sites volts? This lower voltage and current is much safer to use, and is far less likely to cause serious harm if a wire were cut, stepped on or otherwise damaged. Ilenia Wockenpennig Supporter. Can a dryer run on ? Turn off the breaker to the dryer and turn it back on to restore full power. The dryer requires a 30 amp dual breaker or two 30 amp fuses.

Lael Leroy Beginner. Will a v motor run on v? Electric appliances can function with either a full or half-sine wave, whereas electronic devices must have a full sine wave. If you are using a V- V appliance at V , you will need a transformer.

Didimo Lauhoff Beginner. Can I install a volt outlet? Installing a volt outlet isn't all that hard at all. Following the instructions in my video and you'll be fine.

Judiht Schmidmuller Beginner. Does using a transformer use more electricity? It turns out that these transformers consume power whenever they are plugged into the wall, whether they are connected to a device or not.

They also waste power when powering a device.
