What is use of step up transformer?
A step-up transformer increases (or "steps up") the voltage of an alternating electrical current. For example, a step-up transformer could be used to increase 120V AC to 277V AC to provide power to 277V electrical equipment in a building that does not already have a 277V electrical system.Other examples where a step-up transformer might be used include these:Using 240V AC equipment with a 120V AC mains supply.Generating high voltage for use with tubes, such as a CRT.Generating high voltage for use in electric energy distribution.
Which part of a curcuit provides electrical energy?
The Battery! :L hahahaha or a 240v mains socket which ever you choose. but don't fingers in it
What is opposite the word hoist?
lower
Does green have a higher or lower freqenuency?
higher or lower than what?
Will temperature be higher or lower in a mountain?
it is lower temperature when you to mountain,because its cold there
What's wrong with a 240V outlet that tests at 277V?
What's the reading at the service panel? What do regular 115V outlets read at? What kind of meter are you using? Chances are you have 480/277V 3 phase power to this building. Whoever wired the outlet used a 277V feed, possibly because 240V was not avaliable. You should call an electrician, repair of this problem may involve instalation of a transformer.
Will a bulb rated at 277V work in a fixture that is 240V?
Yes, it will just not be quite as bright as it would be on the higher voltage circuit. You will see very little difference in the luminance.
What is low voltage transmission?
In the supply industry it refers to circuits of below 1000 volts. Common voltages used are 120v, 208v, 230v, 240v, 277v, 400v, 415v, 480v.

Where does 277v power used in America?
It is used in Industrial lighting.
How do I connect a single pole 220v switch to a 3 wire 220v motor using 2 hot wires plus 1 ground?
Is it a single pole switch, or a (220)240v switch? A 240v switch is a double pole switch. It has 4 screws and disconnects both hot sources simultaneously.If it's a single pole 120v/277v switch, that just means you can use it on 120v or 277v circuits. If it's not a double pole switch with 4 screws, it's not the right one. Get a 240v double pole switch for this. You can usually find these at home improvement stores.When you state that the motor is a "three wire" make sure that the phasing is correct and you are not trying to connect up a three phase motor.Before you do any work yourself,on electrical circuits, equipment or appliances,always use a test meter to ensure the circuit is, in fact, de-energizedIF YOU ARE NOT REALLY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.
How many 100amp hour batteries do you need to connect to a 240v inverter to produce the same output as a 5?
what do you mean by 5? an inverter just steps a voltage up from a lower voltage( i assume you are talking about a 12v to 240v inverter) 1:20 ratio. so with 100Ah at 12v you should get 240v at 5amps for 1 hour more batteries in parallel will increase this figure.
Wiring diagram for 277 v ballast?

IS there an adapter for a 240V heater that will allow you to plug it into two 110V outlets?
No. Sounds like a fairly hazardous thing to try as well. If it's to use a heater in the US, then buy a US heater at a lower cost than any adaptor that might do the job for you. If it's to use on a UK building site that has 110V but doesn't have 240V, it breaks all the rules because you end up with 240V where you shouldn't.
How do you convert a 4 prong 240V outlet to a 3 prong 240V outlet?
Disregard the neutral
Does a 31watt 240v motor draw 0.13 amps?
yes, 31watt divide 240v equals to 0.13amps.
277 volt heater runs on 240 volts?
Yes and No. A 277 volt heater uses 1 "hot" wire and a neutral, And 240 volt uses TWO hots (120 volts each) and NO neutral unless it has a 120V blower unit just to get that out there. Theoretically you could use 240 volts. Because 240 volts is a Lower (and there are also heaters 120v Hot to Neutral btw) voltage you would Decrease the wattage output of the heater itself which would violate the UL rating of the heater. Here's the Math. Rated Voltage x Rated Amperes = Rated Wattage Output. So if you have a 1500W unit @ 277V it draws 5.41A. Now that you know that you take Ohms Law to find the total Resistance of the Unit which would be 277A / 5.41 = 51.1 Ohms/Resistance. If you take Ohms Law again but for Amperes and factor in 240V instead the math would be 240 / 51.1 Ohms =4.69A. Now take 240V x 4.69A = 1125Watts. You can see that the output is way lower then the maximum rating of the heater. This is for purely resistance heaters like baseboard and and Ceiling Tile heaters. None the less if you installed this on 240V and it is not UL or CE listed for it you violated the rating and the National Electric Code. If you want a better idea look at 240V heaters most are Dual rated for 240V and 208V and you will see the same difference in output wattage listed on the unit.
