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.


Can you plug a 250V appliance in a 220V outlet?

Shouldn't be a problem. The 250V is likely a maximum rating and it is designed for 220-240 V service. Just make sure the current draw is less than the circuit breaker rating.Another AnswerIf you are referring to a European residential service, then you should be aware that the nominal voltage is 230 V, not 220 V, and there are no such things as 250-V appliances. An appliance's rated voltage will always match the nominal voltage of the supply they are designed to operate from.But you should be aware that 230 V is a 'nominal', or 'named', value -the actual value is allowed to increase by 10% -in other words, it can be up to 23 V higher than its nominal value. This means that you can expect a 230-V supply to vary up to 253 V.


Are 277V lights wired the same as 120V?

The connection diagram is the same, one hot-leg and one neutral. But if you do not have 277 volts as your source voltage, connecting a 277 volt light (usually a ballast) to 120 volt will not work. Conversely, if you hook up a 120 volt light or appliance to 277 volts, it will quickly become toast.

Why use 277v light fixtures instead of 110v light fixtures?

277v light fixtures are more efficient to operate and less expensive to install than a 110v fixture of identical wattage. 277v light fixtures are typically installed when 480V 3 Phase primary electric service supplies a commercial or industrial facility. 277v lighting circuits are single phase circuits using one of the 480v primary phases (A,B & C) to Neutral. The higher voltage allows more fixtures per circuit using smaller conductors and longer runs typically required in warehouse lighting applications. ( Amps = Watts/Volts: 400W/277V Fixture = 1.4 Amps, 400W/110V fixture = 3.6 Amps) With 480V 3 Phase primary service, 110V Single Phase power is created using a Step-down transformer. The voltage transformation process consumes power (kWh) and the 277V fixture will consume less kWh than a 110V fixture if identical wattage, especially in fixtures with ballasts such as fluorescent or High Intensity Discharge (HID), like Sodium, Metal Halide or Mercury Vapor.


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.


What safety features are required for a 277 volt light circuit?

Don't let anyone touch the live electrical parts. This voltage is significantly more dangerous than 120V. If you touch it it's likely to grab you and not let go. All components must be rated for the voltage in question. Switches must be rated for 277V, as well as lights, all boxes, junctions, and all electrical wiring must have insulation rated for 277V or above. The circuit breakers must be rated for this voltage, and they must be rated for the available fault current which could pass through the wiring of the circuit, based upon this new voltage. Because this circuit is more than 150V to ground, there are more strict rules on who may perform the work. Review the rules for your locality before cracking any covers. It's likely you should be a licensed electrician before tinkering with this stuff.


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.


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 the voltage rating of a motor on a 3 phase 4 wire 277V lighting circuit?

If the motor is a three phase the most likely voltage the motor operates on will be 480 volts.


What is the difference in amps used by lighting wired 277v vs 208v?

Answer for USA, Canada and countries running a 60 Hz supply service.Assuming you are using the same fixture, and assuming the fixture can operate on either voltage, you will get fewer amps with 208v than with 277v. However, a fixture designed for 208v will probably burn up on 277v, and a fixture designed for 277v will probably not produce any light on 208v.The two fixtures in reality are quite different. The 277v fixture is using one leg and neutral of a 277/480v 3 phase 4 wire system and the 208v fixture is using 2 legs of a 120/208v 3 phase 4 wire system.In commercial and industrial installations the 277v fixture is most common.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.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-energized.IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.


Can you lower 277v to 240v?

With a transformer.


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.


Does a 277 volt fluorescent fixture cost less to operate than a 120 volt fixture?

Not necessarily. It's the wattage of the lamps that determine how much power is used. 277V lighting merely allows for more lights to be on a circuit than if they were on a 120V. The current that is printed on the ballast, times the voltage the ballast is connected to, is what determines the cost to operate the fixture. This is the true wattage of the fixture. The wattage of the lamps are independent as new electronic ballasts can power a numerous amount of tubes of various wattages.
