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.

Can 120v and 277v be in the same conduit?

No this is a very bad idea.


How are lights wired in the house?

A single light, in a single circuit, is wired in series in the circuit. Any additional lights on the same circuit are wired in parallel with the first light.


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


How do you convert 120V to 277V?

277 Volts is derived from one phase of a 480 volt, 3 phase Wye wired transformer to the Neutral or grounded leg of the same transformer. Typically, 480 volt, 3 phase power is for commercial and Industrial use. If you have 120 volt power, you could, by means of boost transformers, increase the voltage to 277 or something close. However, I not sure that you will achieve the same result as with the afore mentioned 480 volt, 3 phase.


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.


Why are buildings are 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


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 .

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 you wire five lights between 3 way switches?

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.


How you can quickly determine whether a string of lights is wired in series or parallel?

on applying same power the one which glows brighter is the one connected in parallel connection.


What is 270 volts?

I believe you mean 277v, but 270 would be considered the same thing. 277v is the voltage to ground of one phase of a 3 phase 480v system. If you are not an electrician, don't worry that 3 x 277 is more than 480. Just trust me. In commercial and industrial installations, 277v is commonly used for lighting and 480v is used for machinery.


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.

1988 prelude no tail lights or dash?

The dash lights and tail lights on a 1988 Honda Prelude are wired into the same circuit. Open, frayed, or burnt wires in any of the systems can the lights to ceased functioning. Check the number 13 10A fuse in the cabin fuse box, if blown take a spark testers and look for any shorts in the wiring.


Why do blinkers reverse light and hazards not work on 95 accent?

Blinkers, Reverses lights and Hazards are all wired into the same fuse. When a short occurs in one of the components all of the lights will cease to function. The fuse should be checked to see if they are in working condition.


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.


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.
