Can LED lights be run on 208v?

Do 208v lights need a neutral?

Nothing needs a neutral to work, it just needs current to flow. In this case you are using two hots just like anything else that uses 208-240v.

What is the difference between 208 and 277?

Just like 120/208 means that between hot and neutral you have 120 volts, and between two hots you have 240 – in a 277/480 service the voltage between hot and neutral is 277 and the voltage between two phase (hot) conductors is 480 volts. … For example 480 / 1.732 = 277 volts, and 120 x 1.732 = 208 volts.

Will a 277V LED light work on 120V?

If the driver is marked 120V-277V, then the answer is yes. The unit will self-adjust to the voltage of the power being supplied as long as it falls within the range shown on the driver.

Is 240 and 277 the same?

Voltage is voltage, no matter how it’s derived. 240 is pretty close to 277, so that’s why it works.

Is 208V two hots?

When you run 120/208V single phase power into an isolation transformer, the two individual hot conductors of 120V are combined into one 208V waveform. … When one 120V conductor is created, the remaining voltage is only 88V, which cannot be used by any equipment.

Does 3 phase 208V need a neutral?

If your system only requires three phase operation or single phase 208, a neutral is not required. IF you did need a neutral then you would DERIVE it at your secondary of your service transformer.

Does 240V work on 208?

208V is *not* the same as 240V. 208V is the voltage between phases of a 3-phase “Y” circuit that is 120V from neutral to any hot.

Will 208V work with 277v?

In this case, the answer is yes. LED drivers and fluorescent ballasts marked with a dash between the voltage will function in that range. …

What is 277V?

277 Volts is the input power of choice for most industrial and commercial applications. … Most industrial facilities get their power in a 480/277 volt 3 phase 4 wire system, because 277 is the phase-to-neutral voltage for 480’s phase-to-phase.
