Re: 220v circuit ?
First of all, I am an electrician and I don't think it's gonna save electrics in my opinion if you look at this fomular: Watts=volts X amps , 220v equipments might have less amps but it takes twice the juice, so the wattage is always comes out the same. Please correct me if some one is an expert on this because I was wondering the same thing.

raskal and kona are correct. if you can find 220v equipment and have the circuit to support it, do it.
remember that our energy bills are measured in kW-Hr. typically, 220v equipment uses less current (amps). As a result, if properly selected, motor, chiller, ballast, etc w/ less current draw will also have less power requirement (watts). Less watts means less money on your electricity bill.
of course, someone please do the financial analysis on the cost of 220v equipment vs 120v equipment, and how long it will take to receive a return on investment.

Loc is right, it draws les amps but yet the voltage is double so the wattage is the same. The big advantage is that with more voltage and less amps, the motor runs better at the higher voltage and produces less heat because of the lower amprage. But if you look at the actual specs, the amprage is halved when the voltage is doubled so your drawing the same amount of watts. IE Watts= Voltage times Amps.
Oh and I'm an electromechainal journeyman as well as a radar/missile tech.
That formula is taught in basic electricity courses.

I think we all are correct. The only thing small big diff is the 220V uses 60Hz whereas the 115V uses 50Hz. But one thing In concern is 220V can kill ppl but 115V just give us a shock.
Sorry F18 but your wrong. Thye both use 60 hz. That's the standard for the US. The UK uses 50hz. And besides that 50 or 60 hz makes no diference on how much power the equipment will use.
Also it dosen't matter if it's 115V or 220 V or even 440 V, it can all KILL. It's not the voltage that kills you but the amperage. It only takes about .1 amp to kill you so any of them are dangerious.

There seems to be a little confusion on electrical in our houses so I'll give you a quick breakdown.
All houses in teh US use 60 Hz. All houses, except in maybe some weird remote area, have 220 volt electrical lines going into their breaker pannel. Most newer house have 200 amp service which means the max carrying capacity of the lines going into their box is 200 amps continous.
As for the voltage, if you look up at the three lines coming into your house, two are insulated and one is bare metal. EACH of the inslated lines is a hot line carrying 115 volts. The bare metal line is the netural/ground line. The three lines together give you 220 volts. Inside of your breaker panel, the two 115 volt lines are split and each line usually supplies half of your houses 115 volt requirment. The normal layout of the breakers is that every other breaker is tied to the same 115 volt line. The in between ones are tied to the other 115 volt line. This is so that if you put in a 220 volt breaker, it takes 115 volts from each line as the breaker takes up 2 slots. Hope this helps you guys some.
Still no matter how you dice it up, the electrical formula is still the same, watts = voltage X amperage.

OK, why the heck the US don't use 220V then. Are we weird or are we dump, or we don't like to be the others?Most countries in the world use 220V.

BTW, Blown63chevy, since you are retired Navy, I am just wondering why most electrical devices on aircrafts use 400Hz such as 5VAC 400Hz, 26VAC 400Hz, 115VAC 400Hz?
??? Got me. AS you notice in my post, we also use 60 hz vice 50 hz. Most equipment will work off of either though.
I run my high power tools, ie compressor, tablesaw etc, off of 220 in my garage. They tend to work a little better.

400hz is used not only in aircraft but ships as well. it's used mainly as a refference voltage in equipment because its more accurate. I.E. 400 cycles a min vs 60 or 50 cycles a min. It's also a lot cleaner power for use in electronic equipment because it dosen't have a tendency to have nosie on it which can induce problems in electronic equipment.

I know that the power coming to the pannel is 220V, but why most of our equipments use 110V. Why do we have to convert 220V to 110V. Just leave the way it is and bulid equipments with 200V instead of 110V.

blown63chevy is correct. but how does this relate to the electric bill. I had always heard that you would save money using 220V over 110V. Is is this just a myth? Or does it have to do with the way the meter reads the usage?
If you were building a house and planing a large tank it would be easy to set it up for 220V, but in most other cases I doubt it would be worth it. Most of the equipment we use is not readily available in 220V versions in the USA. Large pumps being the only exception I know of.
