Are 277V lights wired the same as 120V?

Answer 1

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.

Answer 2

Yes, lights operating at 277V are typically wired in a similar manner to 120V lights, with the main difference being the voltage of the power supply. It is important to use the appropriate electrical wiring and components rated for 277V to ensure safe operation.

Answer 3

No the 277v would be a little less then120v . The 277v pulls less amps

Answer

If 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.

Answer 4

You might be able to use the bulbs if they fit into a 120 volt lamp holder. The light output though, of the 277 volt lamps, will be less using a lower voltage of 120 volts. The voltage of 277 volts is the wye voltage of a three phase four wire 480 volt system.

Answer 5

No, they are designed to be used on supplies of different voltages.
