The impedence of the ballast is system voltage dependent to allow required current to pass through the light fixture. If system voltage changes, the current passing through the light fixture changes, therefore to get designed output from the fixture, the ballast has to be changed.
What else can I help you with?
Can a 1H75 be used with 277V?
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 fixture’s voltage requirements to avoid damage or safety hazards.
How can you attach a 120 v Light Fixture to a 277 v system do I need a ballast so what kinda of ballast?
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.
What is a tri tap ballast?
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.
Wiring diagram for 277 v ballast?
A wiring diagram for a 277V ballast typically involves connecting the incoming 277V power supply to the ballast, and then connecting the ballast to the light fixture. Make sure to follow the specific wiring instructions provided by the manufacturer of the ballast to ensure proper installation and to maintain safety standards. If unsure, it's recommended to consult a professional electrician.
If 227v connected to 120v ballast what happens?
If a 227V power source is connected to a 120V ballast, the ballast may get damaged due to the excessive voltage. It is important to always ensure that the voltage input matches the rated voltage of the ballast to prevent such issues.

What is a reverse connected 120V ballast?
A reverse connected 120V ballast is a type of ballast that can operate a fluorescent lamp with reversed polarity. This means that it allows the lamp to be connected to the power source in reverse compared to a standard ballast, providing flexibility in certain lighting applications.
How do you get a 120 - 480 Volt ballast to work from a normal outlet?
Most often this ballast is actually 120/277. It could be 120-480 though. Look at the diagram on the ballast itself. Many times there will either be a black/white/green, black/red/white/green, or black/orange/white/green set of primary leads. If the ballast has only black/white/green, but it shows more than one voltage, chances are it is automatically adjusted for the line voltage. In this case, just connect the black/white/green to a typical lighting box, and the ballast will light your lamps. If the ballast has more than one color other than white or green, it is a multi-tapped ballast. Normally the black lead is for 120v line voltage and the red or orange is 277v. Don't assume though, refer to the diagram sticker located on the ballast for this information. Hook up the 120v, neutral, and ground to your lighting box, but be sure to cap the unused 277v lead with a wire nut. ----If you do not understand the work well enough to accomplish it yourself properly and safely, don't try it. Consult a professional electrician, as they are proficient enough to do it properly and safely. When working on electrical circuits and equipment, make sure to de-energize the circuit you will be working on. Then test the circuit with a definitive means to make sure it is off (multimeter with metal tipped leads, voltage tester with metal tipped leads, etc., not a non-contact tester, which is non-definitive.)
Is there a way to install a 120V light on a 277V circuit?
No, it is not safe or recommended to install a 120V light on a 277V circuit. The voltage difference could damage the light fixture and pose a fire hazard. It is best to use a light fixture rated for the appropriate voltage.
How many amps does a 1000 watt 120v ballast use?
A 1000 watt ballast operating at 120V would draw approximately 8.33 amps of current. This can be calculated by dividing the power (in watts) by the voltage (in volts).
Can SJ 300V rated wire be used for 277v light?
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.
Does a 277 volt fluorescent fixture cost less to operate than a 120 volt fixture?
Not necessarily. It's the wattage of the lamps that determine how much power is used. 277V lighting merely allows for more lights to be on a circuit than if they were on a 120V. The current that is printed on the ballast, times the voltage the ballast is connected to, is what determines the cost to operate the fixture. This is the true wattage of the fixture. The wattage of the lamps are independent as new electronic ballasts can power a numerous amount of tubes of various wattages.
Holophane ballast re400mh48hrw how do i wire them and are they 120 or 220?
On your model number the figures after 400MH are the voltages for that ballast. A 40 represents 240 volts, 12 represents 120 volts and yours 48 represents 480 volts. Looks like this is a industrial fixture and not meant for residential use.
