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.

∙ 11y agoNo the 277v would be a little less then120v . The 277v pulls less amps
AnswerIf you are referring to a 100 W that is rated at 120 V and a 100-W lamp that is rated at 277 V, then the answer is that each would cost exactly the same, as each draws energy at the same rate -i.e. 100 W.
If, on the other hand, you are talking about running a 100-W/120-V lamp at 277 V then, assuming it doesn't simply burn out (!), then, at 277 V, your lamp would be operating at a significantly higher power than just 100 W, so it would cost more to run.
Don't forget, you pay for energy not current -so the amount of current drawn is irrelevant to this question. The power rating indicates how much energy you are using per unit time.

How do you convert 277v to 120v for an outlet?
i think you just have to change the breaker from a 277 to a 120. 277 breakers are usually a 2 pole breaker and 120 is a single pole breaker. NO. 277v is not two poles, it is one pole, one single pole breaker in a 480 volt 3 phase system (typically). If you want 120 volts from a 277 volt source you need a step down transformer 277 volt to 120 volt , or 480/277 to 120/208 .
Can you use a 600v fuse in a 120v circut?
Yes, as long as the amp rating is the same. Examples, 600v 100amp fuse can be used in a 120v 100 amp's location.
Can you use a 120v cord that will fit a 240v socket the appliance is 240 and the cord is thick?
120v and 240v cords usually have different end configurations and will not plug into the different recepticles. However, if you changed the plug end, and the cord has the proper size rating, then yes, you could use the same cord. But, it also depends on the cord too. Most 120v cords only have three wires in them. One "hot one "neutral" and one "ground" wire. A 240v cord would have FOUR wires, two "hot" wires, one neutral wire, and one ground wire. Therefore, if you changed the voltage from 120v to 240 using a 3 wire cord, you'd not have a ground wire and that could be VERY dangerous. Note that occasionally a 240v device (e.g. some motors) will only need three wires (red,black,green, no neutral) and can be wired with a 120v cord if the cord is rated for 240v.
Is it ok to use a 120v light switch in place of a 125v light switch?
yes, as long as the wattage are almost the same which is similar to the same current
Why would a high watt lamp draw more current than a low watt lamp?
Power is measured in Watts, power (Watts) = E (volts) x I (current - amps) current is determined by the internal resistance (R) of the lightbulb, the lower the resistance the more current will flow. 120v x 0.5a = 60W 120V x 0.83a = 100W the 100W lightbulb will draw more current We also have Ohm's law: E(volts) = I (amps) x R (ohms) Household voltage stays the same at 120v we have for a 100w lamp: 120v = I x R R = 120v/0.83 amps R = 144.6 ohms for a 60w lamp: 120v = I x R R = 120v/0.5 amps R = 240 ohms The higher watt lamp has lower resistance.
Why are tree lights wired in series?
when lights are wired in series same amount of current flows through each light through out wire so the intensity of lights dont decrease and all lights glow with same intensity
Can a 120V chandelier be hard-wired to a 240V power source in Europe using 240V bulbs and will the wires handle the load?
as long as the total WATTAGE of the bulbs is the same, you should get the same light and the wires will handle the load just fine.
What wattage of heaters would you use if 2 are wired in series with 120 vac to equal same as 2 heaters of 210 wattage each wired in parallel?
-- Two loads ... each of which dissipates 210 watts on a 120V supply ...when wired in parallel, dissipate 420 watts.-- Two others in series also want to dissipate 420 watts, so each of thosedissipates 210 watts on a 60V supply.Power dissipated is proportional to the square of the voltage, so on a 120V supply,each of these would dissipate 840 watts .
Why are buildings wired using parallel circuits rather than series circuits?
So you don't have to turn on all the lights at the same time.
Why would plugging in an AC unit in a wall receptacle cause the fuse to blow or breaker to trip?
Is the receptacle a 110 or a 220 outlet? If it's a 110, it needs to be a 220. Are there other appliances, lights, etc. wired on the same outlet? If so, you may have to re-wire so that no other appliances, lights, etc. are wired into the same breaker. Usually the larger appliances such as air conditioners, central heat systems are wired to a separate breaker or fuse.
Are 120V and 208V the same?
no 208v is bigger
Why won't your dashboard lights work after installing a new stereo?
you prob touched a bare earth. there is usually separate fuse for dash lights check them all should be a 10 amp fuse I had the same problem what was wrong with me is when it was wired up the person had a wire wired up wrong and everytime i would turn my light on it blew a fuse, check and make sure the wires are wired up right.
You have no tail lights or lights on your instrument panel on a 1995 Chevy Lumina but have headlights and blinkers?
Man vehicles have the dash lights and tail lights wired through the same fuse. Check your fuse box for the dash or tail light fuse. Something has most likely caused it to blow.
How do I get the button on the automatic gearshift of my car to push in because it is stuck and will not get out of park?
Did you check operation of stop lights? They are wired into same circuit--if fuse blown neither will work
Are the backup lights and license plate lights on a 2002 Buick Century wired in series?
No because the licence plate light would only light up when you put the car in reverse. it is a seprate system. On the 2003 they are on the same fuse.
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.
Tail lights and dashboard are out when headlights are on on a Nissan Pathfinder?
if your installed a new radio double check your wiring most likely the ground of the radio isn't wired right Or: The dashboard is wired to the tail light circuit and both are controlled by the same fuse. The 10amp fuse is in under the hood fusebox passenger-side next to the battery and is labeled TAIL, but includes the dashboard running lights.
