To attach a 120V light fixture to a 277V system, you will need a step-down transformer with a 277V primary and 120V secondary. This will allow you to safely power the light fixture at the correct voltage. You do not need a ballast in this case, as ballasts are typically used with fluorescent lights and not for altering voltage levels.
No, SJ type wire is not rated for 277V application. This wire is typically designed for lower voltage applications such as 120V or 240V. It is important to use wire with the appropriate voltage rating to ensure safety and compliance with electrical codes and standards.
No, a 1H75 ballast is designed for 120V input voltage. You would need a ballast specifically rated for 277V to operate fixtures at that voltage safely and effectively. It is important to match the input voltage of the ballast with the fixtureβs voltage requirements to avoid damage or safety hazards.
A tri-tap ballast is a type of fluorescent light ballast that is designed to accommodate three different input voltages (120V, 277V, and 347V). This flexibility allows the ballast to be compatible with various power sources, making it useful in different settings where voltage requirements may vary.
No, a 277V ballast is designed to work with a 277V power supply, while a 120V ballast is designed to work with a 120V power supply. Using a 277V ballast with a 120V power supply can damage the ballast and may cause safety issues. It is important to match the voltage of the ballast with the voltage of the power supply.

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.

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.
In the supply industry it refers to circuits of below 1000 volts. Common voltages used are 120v, 208v, 230v, 240v, 277v, 400v, 415v, 480v.

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